How to competently make the cooling of the PC housing. ¡- Gweet on water cooling systems (s)

And as far as it can be effective. The need for liquid cooling appeared due to the fact that it was decided to dispersed the processor, and the faster it works, the stronger heats up. That is, the standard cooler has not been enough, and the cooling system is quite expensive.

Materials and tools for homemade:
- heat exchanger or water supply;
- cooling radiator (from car);
- pump (centrifugal water pump with 600 liters per hour);
- expansion tank (in our case);
- four fans with a size of 120 mm;
- power supply for the fan;
- Various other consumables and tools.

Self-timer manufacturing process:

Step one. Production of water unit
The water-block is necessary in order to maximize it efficiently to divert heat from the processor. For such purposes, materials will be needed with good thermal conductivity, copper has been chosen by the author. As an option, aluminum can be used, but its thermal conductivity is half less than in copper, that is, aluminum is 230W / (M * K), and at the copper 395.4 W / (M * K).








It is also important to develop the structure of the water block for effective heat removal. The water-block must have several channels for which water will circulate. The coolant should not be stuffed and water should circulate through the entire water supply. It is also important to make the area of \u200b\u200bcontact with water as much as possible. To increase the area of \u200b\u200bcontact with coolant, frequent cuts can be applied on the walls of the water block, well, you can still install a small needle radiator.


The author decided to go along the path of the smallest resistance, therefore, the water capacity with two tubes for feeding and selecting was made as anterod. As the basis, a connector for pipes from brass was used. The base served as a plate of copper with a thickness of 2 mm. From above, the water-block is also closed by such a copper plate into which the tubes under the diameter of the hoses are installed. The whole design is soldered by tin lead soldier.

As a result, the drill turned out to be quite large sizes, which was reflected on his weight, in the assembled state on the motherboard there was a load of 300 grams. And this led to additional costs. To make it easier for the design, you need to come up with an additional system of fasteners for hoses.

Water exchange material: copper and brass
The diameter of the fittings is 10 mm
Build by soldering tin-lead soldier
The design is fastened with screws to the store cooler, the hoses are additionally fixed using clamps
The cost of homemade at this step in the area of \u200b\u200b100 rubles.

More about the assembly of the water block
As the assembly process occurred, you can see in the photo. That is, the necessary blanks were cut out of the copper sheet, the tubes are embedded, well, and then with the help of the soldering iron, everything was combined into the finished organ system.


























Step second. We understand with Pompey
Pumps can be divided into two types, it is immersed and external. External pump passes water through itself, and the immersible pushes. The author used a submersible type of pump for his self-herring, because there was failed to find outdoor anywhere. The capacity of such a purchase pump is ranging from 200 to 1400 liters per hour, and they are in the area of \u200b\u200b500-2000 rubles. As a power source, there is a regular outlet here, consumes the device from 4 to 20 W.

To reduce noise, the pump must be installed on a foam or other such material. The reservoir served as a pump in which the pump was placed. To connect silicone hoses, we needed metal clamps on the screws. So that in the future it is easy to wear and remove the hoses, you can use a smell lubricant.






As a result, the maximum pump performance was 650 liters per hour. The height on which the pump can raise water is 80 cm. The required voltage is 220V, consumes the device 6W. The cost is 580 rubles.

Step Three. A few words about the radiator
From how qualitatively the radiator will work, the success of the whole ventilation will be dependent. For a homemade, the author applied a car radiator from the Zhiguli stove of the ninth model, it was bought on the flea market for only 100 rubles. Due to the fact that the distance between the radiator plates turned out to be too small so that the coolers were able to drive through it through it, they had to push them.


Radiator characteristics:
- tubes are made of copper;
- radiator aluminum ribs;
- dimensions 35x20x5 cm;
- The diameter of the fittings is 14 mm.

Step fourth. By blowing radiators

To cool the radiator, two pairs of coolers 12 cm are used, two are installed on one side and two on the other. For fans, a separate 12V power supply was used. They are connected in parallel with the polarity. If you confuse polarity, the fan can be spoiled. Black is designated minus, red plus, and the speed values \u200b\u200bare transmitted.
The fan current is 0.15a, one costs 80 rubles.




Here, the author, the author considered the effectiveness and low cost of the device, so no effort was made to reduce noise. Cheap Chinese fans themselves are quite noisy, but they can be installed on silicone gaskets or make other fasteners to reduce vibrations. If you buy more expensive coolers worth 200-300 rubles, then they work more quietly, but at maximum turns still noise. But they have high power and consume 300-600 mA.

Pitch fifth. Power Supply

If there is no needed power supply under hand, then it can be collected with your own hands. It will take an inexpensive microcircuit for 100 rubles and several other available items. For four fans, you will need a current at 0.6 a, and of course you need to have a little in stock. The collected microcircuit produces about 1a at a voltage in the 9-15V region depending on the specific model. In general, any model is suitable, it is possible to change the voltage using an alternating resistor.






Tools and materials for power supply:
- soldering iron with a solder;
- microcircuit;
- radio components;
- Isolation and wires.
The issue price is 100 rubles.

Step six. The final stage. Installation and verification

Pipe computer:
- Intel Core i7 960 processor 3.2 GHz / 4.3 GHz;
- Thermal Cap of Al-Forces 3;
- OCZ ZX1250W power supply;
- Motherboard ASUS Rampage 3 Formula.

Used software: Windows 7 x64 SP1, REALTEMP 3.69, PRIME 95, CPU-Z 1.58.

It's no secret that when the computer is working, all its electronic components are heated. Some elements are warm very noticeable. The processor, video card, northern and southern Motherboard bridges are the worst elements of the system unit. Overheating is generally dangerous and leads to an emergency disconnection of the computer.

Therefore, the main problem of the entire electronic part of the computing equipment is the correct cooling and effective heat removal. The overwhelming majority of computers, both industrial and homely, for heat removal is appliedaerial cooling. She received his popularity at the expense of its simplicity and low cost. The principle of this type of cooling is as follows. All heat from heated elements is given to the surrounding air, and hot air in turn with the help of fans from the system block housing. To increase heat transfer and cooling efficiency, the most heated components are supplied with copper or aluminum radiators with fans installed on them.

But the fact that heat removal occurs due to the movement of the air, does not at all mean that the more fans are installed, the better the cooling in general. Several incorrectly installed fans can harm much more, and not solve the overheating problem, when one competently installed fan will solve this problem very effectively.

Selection of additional fans.


Before buying and installing additional fans carefully read your computer. Open the enclosure cover, count and find out the size of the installation places for additional cabinet coolers. Look carefully on the motherboard - which connectors for connecting additional fans are available on it.

Fans need to choose the largest size that will suit you. Standard enclosures are 80x80mm size. But quite often (especially lately) in the housing you can install fans with a size of 92x92 and 120x120 mm. With the same electrical characteristics, a large fan will work much quieter.

Try to buy fans with lots of blades - they are also quieter. Pay attention to the stickers - the noise level is specified. If the motherboard has 4 pin connectors for food coolers, then buy four-wire fans. They are very quiet, and the range of automatic revolutions is quite wide.

Between fans receiving power from the power supply throughmolex connector And working from the motherboard unequivocally choose the second option.

There are fans on sale on real ball bearings - this is the best option in terms of durability.

Installing additional fans.


Let's consider the main points of the correct installation of body fans for most system blocks. Here we give advice for standard buildings, since the non-standard location of the fans is so diverse that it does not make sense to describe them - everything is individually. Moreover, non-standard enclosures of fans can reach 30cm in diameter.

There are no additional fans in the housing.

This is a standard layout for almost all computers sold in stores. All hot air rises into the top of the computer and at the expense of the fan in the power supply, it turns out.


A large disadvantage of this type of cooling is that all the heated air passes through the power supply, heating at the same time it is even stronger. And therefore, it is the power supply that such computers breaks most often. Also, all cold air is absorbed not controlled, but from all the enclosures, which only reduces the effectiveness of heat exchange. Another disadvantage is the affixiness of air obtained with such a type of cooling, which leads to the accumulation of dust inside the case. But still, it is in any case better than the wrong installation of additional fans.

One fan on the back of the housing.

This method is applied more from hopelessness, as there is only one place in the case to install an additional cooler - on the rear wall under the power supply. In order to reduce the amount of hot air passing through the power supply, one fan is installed on the "blowing" from the housing.


Most of the heated air from the motherboard, processor, video cards, rigid disks go through an additional fan. And the power supply at the same time is heated significantly less. Also, the total flow of moving air increases. But the affliction increases, so the dust will accumulate even stronger.

Additional frontal fan in the case.

When the case has only one seat on the front of the case, or there is no possibility of incorporating two fans at once (it's nowhere to connect), then this is the most perfect option for you. It is necessary to put one fan on the front part of the housing on the "blowing".


The fan must be installed opposite the hard drives. And it will be more correct to write that the hard drives must be installed opposite the fan. So the cold incoming air will immediately blow them. This installation is much more effective than the previous one. A directional air flow is created. The vacuum is reduced inside the computer - the dust is not delayed. When feeding additional coolers from the motherboard, the overall noise is reduced, as the fan turns are reduced.

Installing two fans into the case.

The most efficient method of installing fans for additional cooling of the system unit. On the front wall of the case, a fan is installed on "blowing", and on the back wall - to "blow out":


A powerful permanent air and directional flow is created. The power supply works without overheating, as the heated air is outputting the fan installed below it. If the power supply is installed with adjustable fan rotation turnover, the general noise will noticeably decrease, and that more importantly, the pressure inside the housing is aligned. Dust will not settle.

Incorrect installation of fans.


Below, we give examples of the unacceptable installation of additional coolers in the PC housing.

One rear fan is installed on "blowing".

A closed air ring is created between the power supply and the additional fan. Part of the hot air from the power supply is immediately absorbed back inside. In this case, at the bottom of the system unit of the air, there is no air, and therefore the cooling is inefficient.



One front fan is set to "blowing out".

If you put only one front cooler, and it will work on blowing, then in the end you get a very discharged pressure inside the case, and ineffective cooling of the computer. Moreover, due to reduced pressure, the fans themselves will be overloaded, since they will have to overcome the opposite pressure of the air. Computer components will be heated, which leads to increased noise of operation, since the speed of rotation of the fans will increase.




Rear fan on "blowing", and frontal - to "blowing out".

Aerial short circuit between the power supply and the rear fan is created. Air in the area of \u200b\u200bthe central processor works in a circle.


The front fan is trying against the natural convection lift "omit" hot air, working under an increased load and creating a vacuum vacuum.


Two extra coolers stand on "blowing".

A thermal short circuit is created in the top of the case.


At the same time, the effect of incoming cold air is felt only for the hard drives, as it falls on the oncoming flow from the rear fan. Excessive pressure is created inside the housing, which complicates the operation of additional fans.

Two additional coolers work on "blowing out".

The hardest mode of operation of the cooling system.


Inside the housing, low air pressure, all body fans and inside the power supply are under refund pressure. There is no sufficient air movement inside the air, and, therefore, all components work overheating.

Here in principle, and all the highlights that will help you in organizing the right ventilation system of your personal computer. If there is a special plastic corrugation on the side cover of the case - use it to supply cold air to the central processor. All other installation issues are solved depending on the structure of the hull.

The project "Gnome" - the idea of \u200b\u200bcreating his without an expansion tank was due to the fact that this element is either roads in acquisition (if you still find on sale), or difficult to manufacture. Beautiful expansion tank requires diligence, accuracy and tools at hand. The budget option is also possible, but loses in appearance. In addition, the expansion tank is another additional element of its who can give a leak. So why not give up him at all?

Many water cooling enthusiasts, as well as the experienced users who themselves created their own, will find more than the absence of a tank, rather than advantages. Traditionally, its presence belongs to the simplicity of refueling system and removing air bubbles. Coney can not be noticed, since they can not really be in the case of an experienced user. But what to make an inexperienced person, before which the task of creating effective cooling of their PCs? In this case, there is always a choice - to purchase a Hi-end air cooler, but their price has long been approaching $ 60 or more, and should not be doubted that new models will be more and more expensive. Although the air cooler is relatively easy to purchase, this is the unconditional advantage of air cooling.

The future requirements for the project "Gnome" are gradually identified - relatively small, but definitely powerful. Small and powerful - true hero of fabulous stories:

1. The project should be easy to manufacture even for beginners.
2. It should not take a long time, actually the time can be installed on 1 day to purchase all components and assembly.
3. The cost should not be too high. We think the price of the Hi-end cooler at $ 60. It will be a good guideline.
4. The size of the entire system should not excessively increase. Who hunting to turn your PC into an absolutely non-transportable box? Although handling the system unit will still have caution, as in the case of use, for example, Cooler Master Hyper 6.
5. Safety. Everything happens, in the absence of experience, it is easy to miss anything important. Let's try minimize the danger of leakage, so you delete from your tank. However, it can always be added to the system, so at the end of the article will be the method of the most simple manufacturer of the expansion tank. Of course outside the project.

We decided with the requirements, now let's see what we need:

  • Waterblock is the most difficult part of the project. The cost of serial products begins from $ 22. In fact, the timing of the project is given by the deadlines for receiving the Waterblock on the hands, in free sale throughout the country can be found, but it is already a little more expensive.
  • Radiator - as a radiator, choose domestic products from the stove of the car A / m Gazelle. A rather good copper radiator, which is well blowing. One of the experiments can be read. Cost from $ 20.
  • Pomp - Pompe we take a submersible with an eye on the alteration into external. In this case, this is Heto QD-2800, the review and process of rework you can also look at. If you do not find Heto pump, then choose any similar constructive design. The QD-2800 model costs $ 13.
  • Hoses - 1-1.5 m hose with an internal diameter of 13 mm and 1 m with an inner diameter of 8 - 10 mm (depending on the fittings of the Vaterlember). 10 - 40 rubles per meter in the case of PVC and approximately twice as much as silicone hoses.
  • Plumbing is a special fittings that will allow us to abandon the expansion tank, passing the role of adapters from thick hoses to thin. Two crane "for washing machine" (100 rubles), 3 - 4 fittings of the desired diameter with the necessary thread (at 20 rubles). TOTAL about $ 10.
  • Fan - For high efficiency, it is necessary by blowing the radiator. From $ 3 for 120 mm fan.
  • Distilled water - from 1 l, less than $ 1 per liter.
  • AVTOGERMETAL "Kazan Silicone" - $ 1 for a small tube.

Sealant "Kazan Silicone" the best that came across in hand. Indispensable in the process of creating its. As you see all the items are easy enough to find. You need to go to aquarium store, auto parts store, plumbing and computer firm.

Assembly

In the process of assembly there is nothing complicated, the main thing is not to rush. All the joints are abundantly missed by sealant, the surplus is then easily removed by a piece of paper or if the sealant froze, then neatly cut off with a knife. For starters in external.

Then, instead of the suction fitting of the pump, screw the "crane for a washing machine" - in the stores it is called this way. Screw also through the sealant. Be careful if using the HETO QD-2800 pump, not its older brother, since the clamping ring (blue in the photo) is thin and the camera cover is easily scrolled. Do not allow this to happen, as tightness depends on it. For older Heto models, it is uncharacteristic, since the pressure ring is larger.


Collect the second crane. Thus, he still plays the role of an adapter with a 13 mm hose by 8-10 mm. You can do without a second crane, but with it the process of refueling in consideration is not more difficult than when using the expansion tank.

Almost everything is ready, it remains only to cut 13 mm hose and put on the radiator. The photo shows the new Waterblock from Promodz, the overview of which you can read in the near future.

It is necessary to connect the suction indoor polar floor fitting with the lower radiator fitting if the radiator remains in the finished system "on the side". If the radiator will be suspended behind the system unit - then to any stacker. In the case of a horizontal location, connect the suction hose with the fitting, which will be lower than the other. It is necessary that the remaining air in the system is caught by the radiator and not "walked", breaking silence. The amount of air will be very small, but sufficient to provide a place for the thermal expansion of water. Thus, the radiator in the project will serve us the similarity of the expansion tank, taking the compensatory function.

Water cooling systems have been used for many years as a highly efficient heat removal tool from the heating components of the computer.

The quality of cooling directly affects the stability of your computer. With excess heat, the computer begins to hang and the failure of overheated components is possible. High temperatures are harmful to the element base (capacitors, chip, etc.), and overheating hard disk can lead to data loss.

With increasing performance of computers, you have to use more efficient cooling systems. The traditional is considered an air cooling system, but the air has a low thermal conductivity and a strong noise is created with a large air flow. Powerful coolers make a rather strong roar, although it can provide acceptable efficiency.

In such conditions, water cooling systems are becoming increasingly popular. The superiority of water cooling over the air is explained by the heat capacity indicators (4,183 kJ · kg -1 · k -1 for water and 1,005 kJ · kg -1 · k -1 for air) and thermal conductivity (0.6 W / (m · k) for water and 0.024-0.031W / (M · K) for air). Therefore, with other things being equal, water cooling systems will always be more efficient than air.

On the Internet you can find many materials on ready-made water cooling systems from leading manufacturers and examples of homemade cooling systems (the latter are usually more efficient).

Water cooling system (its) is a cooling system in which water is used to transfer heat as a coolant. In contrast to air cooling, in which heat is transmitted directly, in the water cooling system, the heat is first transmitted to water.

The principle of work isa

Computer cooling is necessary to remove heat from the heated component (chipset, processor, ...) and dispersion. An ordinary air cooler is equipped with a monolithic radiator that performs both function data.

In his each part performs its function. The water unit carries out a heat unit, and the other part dispels thermal energy. An exemplary compound scheme of its components can be viewed in the diagram below.

Water blocks can be turned on in the circuit in parallel and sequentially. The first option is preferable in the presence of identical heat supply. You can combine these options and get a parallel-sequential connection, but the most correct will be the connection of the water blocks one by one.

Heat removal occurs according to such a scheme: the liquid from the tank is supplied to the pump, and then pumped further to the nodes that cooled the PC components.

The reason for this connection is a slight water heating after passing the first water block and the effective heat removal from the chipset, GPU, CPU. Harbor fluid enters the radiator and is cooled there. Then she gets into the tank again, and a new cycle begins.

According to constructive features, it can be divided into two types:

  1. The cooling fluid circulates due to the pump in the form of a separate mechanical node.
  2. Communication systems in which special refrigerants passing through a liquid and gaseous phase are used.

Cooling system with pump

The principle of its action efficiency and simple. The liquid (usually distilled water) passes through radiators of cooled devices.

All components of the design are connected by flexible tubes (diameter 6-12 mm). The fluid passing through the processor radiator and other devices, takes their heat, and then on the tubes falls into the heat exchanger radiator, where it is cooled. The system is closed, and the liquid in it is constantly circulating.

An example of such a compound can be shown on the example of CoolingFlow products. It is combined with a buffer tank for fluid. Arrows show the movement of cold and hot liquids.

Silent liquid cooling

There are liquid cooling systems that do not use the pump. They use the principle of the evaporator and the directional pressure is created that causes the coolant movement. Fluids with low boiling point are used as refrigerants. The physics of what is happening the process can be considered in the diagram below.

Initially, the radiator and highways are completely filled with liquid. When the temperature of the processor radiator becomes above a certain value, the liquid turns into steam. The process of converting fluid into steam absorbs thermal energy and increases cooling efficiency. The hot ferry creates pressure. Couples, through a special unilateral valve, can only go out in one direction - into the radiator of the heat exchanger-capacitor. There, steam displaces the cold liquid in the direction of the processor radiator, and, cooling, turns into a liquid again. So the liquid pairs circulates in the closed pipeline system, while the radiator temperature is high. Such a system is very compact.

Another version of this cooling system is possible. For example, for a video card.

A liquid evaporator is embedded in the graphic chip radiator. The heat exchanger is located next to the side wall of the video card. The design is made of copper alloy. The heat exchanger is cooled with a high-speed (7200 rpm.) A centrifugal fan.

Components free

In water cooling systems, a specific set of components, mandatory and optional are used.

Mandatory components:

  • radiator,
  • fitting,
  • waterblock,
  • water pump,
  • hoses
  • water.

Optional components are: thermal sensors, tank, drain cranes, pump controllers and fans, minor vaterblocks, indicators and meters (flow, temperature, pressure), water mixtures, filters, backpoints.

  • Consider compulsory components.

Waterblock (English Waterblock) is a heat exchanger that transmits heat from the heated element (processor, video chip, etc.) water. It consists of a copper base and a metal cover with a set of fasteners.

The main types of Waterblocks: Processor, for video cards, on a system chip (North Bridge). Waterblocks for video cards can be of two types: closing only graphic chip ("GPU only") and closing all heating elements - Fullcover (eng. Fullcover).

Waterblock Swiftech MCW60-R (GPU-Only):

Vaterblok EK Waterblocks EK-FC-5970 (Full):

To increase the heat transfer area, a microchannel and microfield structure is used. Waterblocks are made without a complex internal structure if the performance is not so critical.

Chipset Waterblock XSPC X2O Delta Chipset:

Radiator. In its radiator, they call the water-air heat exchanger, transmitting the air heat from the water in the Waterblock. There are two subtypes of radiators: passive (ignorant), active (blown by the fan).

Bentable can be found quite rarely (for example, in its Zalman Reserator) because this type of radiators has lower efficiency. Such radiators occupy a lot of space and it is difficult to place them even in a modified housing.

Passive radiator AlphaCool Cape Cora HF 642:

Active radiators are more common in water cooling systems due to better efficacy. If you use quiet or silent fans, you can achieve a quiet or silent job. These radiators can be the most different size, but they are mainly made by multiple to the size of 120 mm or 140mm fan.

Radiator Feser X-Changer Triple 120mm Xtreme

The radiator is for a computer case:

Pomp - electric pump, is responsible for circulation of water in the contour of its. Pumps can work from 220 volts or from 12 volts. When there were few specialized components for sale for its sale, then used aquarium pumps operating from 220 volts. This created some difficulties, due to the need to turn on the pump synchronously with the computer. To do this, the relay applied to the pump automatically when the computer starts. Now there are specialized pumps with compact sizes and good performance that run from 12 volts.

Compact pump Laing DDC-1T

There are a fairly high hydrophone coefficient of hydroxistance, therefore it is desirable to use specialized pumps, as aquarium will not allow its fulfillment to work for full performance.

Hoses or tubes are also mandatory components of any of its own, water flows from one component to another. Basically use PVC hoses, sometimes from silicone. The size of the hose does not greatly affect the performance as a whole, it is important not to take too thin (less than 8 mm) hoses.

Fluorescent Hose Feser Tube:

Fittings are called special connecting elements for connecting hoses to components of its (pump, radiator, waterblocks). Fittings must be screwed into the threaded hole located on the component. You need to screw them out not very strongly (whaners keys will not need). Tightness is achieved by a rubber sealing ring. The vast majority of the components are sold without fittings included. This is then done so that the user can choose the fittings itself, under the desired hose. The most common type of fittings is a compression (with a cape nut) and a Christmas tree (fittings are used). Fittings are straight and corner. Fittings still vary by thread type. In computer, the carving of G1 / 4, less commonly, G1 / 8 "or G3 / 8" is more often found.

Water also belongs to the required component of its. It is best to refuel distilled water (purified by impurities by distillation). Deonized water is used, but it does not have significant differences from distilled it, it is only done in another way. You can use special mixtures or water with different additives. But it is not recommended to use water from under the tap or bottled for drinking.

Optional components are components, without which it can stably work, and do not affect performance. They are doing it more comfortable.

The tank (expansion tank) is considered an optional component, although it is present in most water cooling systems. Systems with a tank are more convenient to refuel. The water volume of the reservoir is not fundamental, it does not affect the performance of its. The forms of reservoirs are most different and choose them on the criteria for the convenience of installation.

Tubular tank Magicool:

The tap is used for convenient drain of water from the contour. It is blocked in the usual state, and opens when it is necessary to drain the water from the system.

Drain Crane Koolance:

Sensors, indicators and meters. There are quite many different meters, controllers, sensors for its. Among them are electronic water temperature sensors, pressure and water flow sensors, controllers, matching the operation of the fans with the temperature, indicators of water movement, and so on. Pressure sensors and water flow are needed only in systems intended for testing components, since this information for a regular user is simply insignificant.

Electronic stream sensor from Aquacompute:

Filter. Some water cooling systems are equipped with a filter included in the contour. It is intended for filtering a variety of small particles in the system (dust, soldering remains, precipitate).

Additives to water and various mixtures. In addition to water, various additives can be used. Some of them are designed to protect against corrosion, others to prevent the development of bacteria in a system or tinting water. We also produce ready-made mixtures containing water, anti-corrosion additives and dye. There are ready-made mixtures that increase its performance, but the increase in productivity from them is possible only insignificant. You can find fluids for its, which are not based on water based, but using a special dielectric fluid. Such a liquid does not conduct an electric current and when leakage, the PC will not cause a short circuit. Distilled water also does not conduct a current, but if shedding, it will fall on the dusty areas of the PC, it can become electrically conductive. There is no need for dielectric fluid, because it does not proceed well and has sufficient reliability. It is also important to comply with the instructions for additives. No need to pour them over measures, it can lead to deposits.

Green Fluorescent Dye:

The backpoint is called a special mounting plate, which is needed to unload the textolite of the motherboard or the video card from the effort created by the fastenings, and reduce the bending of the textolite, reducing the risk of breakage. Beckplast is not a mandatory component, but very often found in his.

Corporate Biscaplate from WaterCool:

Secondary Waterblocks. Sometimes, they put additional waterlines on weakly heat components. Such components include: RAM, power supply circuit transistors, hard drives and southern bridge. The optional components for the water cooling system lies in the fact that they do not carry improvements in overclocking and no additional stability of the system or other notable results do not give. This is due to the small heat generation of such elements, and with the ineffectiveness of the use of Waterblocks for them. Only appearance can be called the positive side of the installation of such Waterblock, and the minus is to increase the hydrosistance in the circuit and, accordingly, an increase in the cost of the entire system.

Waterblock for power transistors on the motherboard from EK Waterblocks

In addition to the mandatory and optional components, there is another category of hybrid components. There are components that are two or more component in one device. Among such devices are known: Pump hybrids with processor Waterlebler, radiators for their combined with integrated pump and tank. Such components significantly reduce their place and more conveniently in the installation. But such components are little suitable for upgrading.

Selecting a system

There are three main types: external, internal and built-in. They differ in the location in relation to the computer's housing of their main components (radiator / heat exchanger, tank, pump).

External water cooling systems are performed as a separate module ("box"), which is connected to Waterleblocks using hoses, which are installed on components in the PC case itself. A radiator with fans, a tank, pump, and, and, sometimes, for pumps with sensors, a power supply unit is almost always taken into the body of the outer water cooling system. Among the external systems are well known to the Water Cooling Systems Zalman Reserator family. Such systems are installed as a separate module, and their convenience is that the user does not need to refine and redo the case of its computer. Their inconvenience consists only in dimensions and it becomes more difficult to move the computer even for short distances, for example, to another room.

External passive Zalman Reserator:

The built-in cooling system is mounted in the case and is sold complete with it. This option is the easiest in circulation, because everything is already mounted in the housing, and there are no bulky structures outside. The disadvantages of such a system include high cost and the fact that the old PC body will be useless.

Internal water cooling systems are completely inside the PC housing. Sometimes, some internal components (mainly radiator) are installed on the outer surface of the case. The advantage of domestic is the convenience of carrying. There is no need to drain fluid during transportation. Also, when installing internal, it does not suffer from the appearance of the case, and when modging it can perfectly decorate the case of your computer.

The disadvantages of the internal water cooling systems are the complexity of their installation and the need to modify the hull in many cases. Also internal adds to your body a few kilograms of weight.

Planning and installing your

Water cooling, in contrast to air, requires some planning before installing. After all, liquid cooling imposes some restrictions that need to be taken into account.

During installation, you should always remember convenience. It is necessary to leave free space so that further work with its and components did not cause difficulties. It is necessary that the tubes with water freely passed inside the housing and between the components.

In addition, the flow of fluid should not be limited to anything. When passing through each water unit, the coolant is heated. To reduce this problem, a scheme with parallel coolant paths is thought out. With this approach, the flow of water is less loaded, and water comes into the water supply of each component, which is not heated by other components.

Well known Koolance EXOS-2 set. It is designed to work with the connecting tubes of the 3/8 section.

When planning its location, it is recommended to first draw a simple scheme. Having draws a plan on paper, proceed to real assembly and installation. It is necessary to decompose on the table all the details of the system and to approximate the desired length of the tubes. It is advisable to leave the stock and do not cut too short.

When preparatory work is done, you can start the installation of waterlocks. On the back of the motherboard behind the processor, a metal bracket of fastening the KOOLANCE cooling head for the processor is installed. This fastening bracket is equipped with a plastic gasket, to prevent closure with the motherboard.

Then the radiator attached to the North Motherboard Bridge is removed. The example uses the Biostar 965PT motherboard, in which the chipset cooling occurs with the help of a passive radiator.

When the chipset radiator is removed, you need to install the elements of fastening the water block for the chipset. After installing these elements, the motherboard put again into the PC housing. Do not forget to remove from the processor and the chipset an old thermalist before applying a thin layer of new.

After that, water blocks on the processor are carefully installed. Do not press them with force. Applying force you can damage the components.

Then work with the video card is carried out. It is necessary to remove the radiator existing on it and replace it with a water unit. When the water blocks are installed, you can connect the tubes and insert the video card into the PCI Express slot.

When all water blocks are installed, all the remaining tubes should be connected. The latter is connected to the tube leading to the external block of its. Check that the direction of water movement is correct: the cooled fluid must first enter the processor's water supply.

After performing all these works, water is poured into the tank. To fill the tank only to the level specified in the instructions. Look carefully for all the fasteners and with the slightest signs of leakage, immediately eliminate the problem.

If everything is properly assembled and no leaks occurred, you need to pump the cooling fluid to remove air bubbles. For the Koolance Exos-2 system, you need to close the contacts on the ATX power supply, and supply the water pump, without feeding the motherboard.

Let the system work slightly in this mode, and you carefully tighten the computer to one, then on the other side to get rid of air bubbles. After the output of all bubbles, add coolant, if necessary. If the air bubbles are no longer visible, then you can run the system completely. Now you can test the effectiveness of its installed. Although water cooling for the PC is still rare for ordinary users, its advantages are indisputable.

The most energy-intensive in the computer is the processor and the discharge of the separable thermal energy is the urgent task, especially when the ambient temperature is high. Not only the stability and durability of its operation depends on the heat heating temperature, but the speed, as processor manufacturers usually silent.

In the overwhelming number of computers, the processor cooling system is performed with ignoring the elementary laws of physics. The system cooler works in a short circuit mode, as there is no screen that eliminates the possibility of suction with a cooler of hot air leaving the processor radiator. As a result, the efficiency of the cooling system of the processor does not exceed 50%. In addition, cooling is made by air, heated by other components and nodes placed in the system unit.

Sometimes an additional cooler is installed in the system unit on the rear wall, but this is not the best solution. Additional cooler works on the pushing of air from the system unit to the environment, like the cooler of the power supply. As a result, the effectiveness of both coolers is much lower if they worked separately - one suck the air into the system unit, and the other pushed. As a result, additional electricity is consumed and what is not pleasant, an additional acoustic noise appears.


The proposed design of the cooling system of the processor is released from the above deficiencies, easy to implement and ensures high cooling efficiency and as a result, other components of the motherboard. The idea is not new and simple, the air for cooling the processor radiator is taken from outside the system unit, that is, out of the room.

I decided to improve the cooling system of the processor of my computer, when the constructive system from the cooling system of the branded, morally obsolete system unit was caught.

It remains to consolidate this item in the system unit and connect with the processor cooler. Since the length of the nozzle was insufficient, it was necessary to increase it with a polyethylene tape, retinue into the tube. The diameter of the tube is selected taking into account the dense landing on the housing of the processor cooler. To the tape does not develop, it is fixed with a metal bracket with a stapler.

The system is fixed using independently made two-corners with screws to the rear wall of the system unit. Accurate positioning relative to the center of the cooler is achieved due to the lengths of the sides of the corners.

Such simple design allowed to practically eliminate the arrival of hot air from the system unit into the processor cooling system.

In the lid of my system unit there was already a finished hole, which simplified work. But it is not difficult to make an independently hole, you need to spread the center of the culper center on the side cover, the circulation to draw a circle, slightly less than the diameter of the tube. Drill a 2.5-3 mm diameter drill with a pitch of 3.5 mm along the entire length of the hole circle line. Drilling points must be pre-stated with core. Then drill drilled holes with a drill with a diameter of 4 mm. The edges of the obtained hole are treated with a circular file. It will only be necessary to install a decorative lattice, although it is not required.

As an air duct, you can successfully use a plastic bottle of drinks. If there is no suitable diameter, you can take more, cut along and sew threads. High tightness is not obligatory here. Fix the tube can be both low screws directly to the cooler case. The main thing is to ensure air supply to the cooling system from the outside.

Temperature measurements showed high efficiency of the Pentium 2.8 GHz processor cooling system. With a 10% processor load, at an ambient temperature of 20 ° C, the processor temperature did not exceed 30 ° C, the radiator was cold on the touch. In this case, the cooler effectively cooled the radiator in the lowest revolutions mode.
