Liquid Cooling Buying

Water Cooling CPU while rarely used in computers and questions as to mount the water cooling system and how effective it is (in percent and degrees Celsius) air system, have not lost their relevance. To answer these questions were collected two system unit, differing only in that one of them had full-time, boxed air cooling system and another water system. In appearance system blocks do not differ from each other, i.e. any recommendations made outside the housing elements of water-cooling system has not. Water cooling is a cooling technique with water as in automobiles. The water quality has in fact much higher thermal conduction to the air (20 times), allowing it to remove the heat generated by your CPU more efficiently than air. Water cooling is very efficient and allows for superior cooling the aircooling. Overclockers adopt this technique for their processors overclocked frequency and voltage.

The advantages this system offers over air cooling are several, better performance with less noise at equal temperature, under normal operating temperatures, greater stability when overclock and a special aesthetic. The disadvantages could talk about all the money and the possibility of a ruling that could disrupt our team (somewhat remote possibility.

Two types of systems exist: LDPC and HDPC. In CPG, the focus is on high throughput and rapid flow, whereas in HDPC it focuses more on a slow passage, the water is heated and cooled for longer, thus improving trade. Both offer good solutions and are equivalent.

• LDPC systems require high flow pumps (1200 l / h), large diameter pipes (12 mm), plenty of fluids, so a large tank and adapted waterblock.
• HDPC systems are smaller and require less liquid, pipes of smaller diameter (8 to 10 mm maximum) and low-flow pumps (300 to 600 l / h maximum) and waterblock with microstructure.

In recent years, computer components become hot, to cool them have to use more efficient cooling system. Despite the reliability, simplicity, low cost of traditional air cooling systems, air has low thermal conductivity, and hence is not the best solution for cooling, not to mention the noise that is created when a large flow of air. Recent cooler publish just a hefty roar, and the efficiency is acceptable, but not always sufficient. In recent years become increasingly popular water-cooling system. Those who ironically looks at this venture, I say that not in vain in the automotive industry uses it this way, remember the infamous Cossack with air cooling, which, despite its weak engine and could not cope with cooling. Water is a much better heat dissipation than air, which is why water system is considerably more efficient aircraft.

Components:

There are many components, and we do not always know what to take, especially when one is beginner to this. Water is supplied through a hose pump waterblock passing through the waterblock, water picks up heat and then fed into the radiator, cooled by the fan assembly. Thus, the heat forced displayed outside the housing. Expansion tank prevents the presence of air in the system increases the volume of fluid (water) in the system, thereby increasing the inertia of the system, besides the water in the tank cools the pump. Inertia of the system in our case - just a big plus, because the processor is usually not continuously at full load. While he was working system gradually heated, and during idle time to cool water. Note that this rule does not always work, I have, for example, the 3200-m processor 1.5 hours of video encoded for 7 hours while the CPU is loaded at 100%.

CPU Fan :

Intended to cool the radiator. Looking for a block of four fans from the people immediately the question arises on account of silence. The fact that all fans are through resistors or you can turn them not to 12V, and at 5V (some may be bad to start) or 7B. At minimum speed they are generally not audible. In the second version I put the 3-position switch, the first position of +12 V (full speed), the second through the resistor 20Om 2W, and the third on two successive 25Om 2W (4W). This made it possible to include large fan speed for long loads, a computer summer heat. Immediately make a reservation, each mode increase / CPU temperature by 1 degree, the water is 2 degrees. The difference is tiny, but the noise at maximum capacity sufficient, but when very hot, it can go on.

The heat exchanger between the water and the environment, helped by fans. The other important element is the radiator. To cool a little CPU, a small radiator 120mm will suffice. But if the CPU heats or you want to add a waterblock GPU (for example), the passage has a 240 is highly desirable. This is the size of the radiator more widespread. There are radiators are optimized for low airflow, ideal for those seeking silence and others more oriented performance. The choice is yours.

Pump:

It is responsible for circulating the water through the circuit and blocks, the data that interests us most about it are the pressure and flow that are capable of providing, indicating that the larger higher performance. Moles may be connected by a plug or normal. There submersible pumps, which are especially convenient because they have a big space savings compared to a pump and tank. They also have a reputation for being quieter, which is not always justified. In any case, know that the current pumps are pretty quiet, it is far from the pumps that shook the boxes.

The heart of the entire cooling system is a water pump, which pumps the water. The reliability of the water cooling system is just depends on her. The most commonly used submersible aquarium pump average performance, they are cheap and the most common. Their disadvantages are: powered by 220, most of the vibration and limiting water temperature to 35 o C.

Blocks:

They are responsible for heat exchange between the devices and for cooling water and there are micro, graphics, chipset and to a lesser extent, hard drives. Ensure that their entries (wrongly called connectors) match on the circuit. Perhaps the most difficult in the manufacture of parts in the system. Typically made from the most heat-conducting material, in order to most quickly transfers heat from the chip coolant (water). The cheapest of the best thermal conductivity material is copper. Slightly better than him - a silver, two times worse - aluminum. Find copper ingots of this size for many is quite a difficult task. I agonized too long in search of material, by the way, it took the longest time. But then I found a place where you can find in abundance all the components of the system - is, as we call it, "Field of Dreams" or the flea markets where people sell, what they had lying around from old times.

The most important water block in the system. Processor, the device is the most hot and requires better cooling. I chose to implement the construction of "spiral", the cold water enters the central portion of the block, when struck in the ground there are turbulent flows, which increase the heat removal from the metal. Design requires a factory made me do it on a machine with the CPU, but some craftsmen manage to do things on his knee with the drill. I have to say, do not like the design on the "snot", so I'm not a supporter of such a fabrication.

Expansion tank :

First you need to modify the cover - and build fill port hole for the cord. Filling hole I made from the top of a plastic bottle of vitamins, and the cord - a rubber stopper of a bottle of medicine. It would be nice also drain hole. Further, done a hole under the fittings in the housing capacity, it is better to do this heating tool to heat. Fittings are attached with nuts on the inside and on both sides sealant. Few of the sealant. Plumbing transparent silicone sealant was not the best option, it is better to use automotive sealant, white, opaque, it has a much better sticking properties, more flexible and strong. Pump to protect from the walls of a thick layer of foam rubber or suspend, or vibration from the pump.

The liquid in the tank. Usually shipped with distilled water, if you pour the usual - it quickly blossoms, all the components in the system no longer work effectively because of the plaque covered them, and generally pump failure. For reliability in distilled water can be added to vodka, alcohol, or automobile coolant (best option). The fact that antifreeze is neutral to aluminum and copper, with such a fluid can combine these two metal in the system, but with plain water.

Coolant:

This transports heat and must have a percentage of anti-algae to avoid unwanted life into the circuit and deionized water in an approximately 10-90 ratio. For the work of anti-algae and to prevent corrosion when aluminum and copper together is often used antifreeze.

Storage:

Allows for a more comfortable filling and emptying of the circuit and to purge it in a more effective, is entirely optional and may be replaced by other forms of filling.

How it works

I will choose Case ThermalTake VE2430SWAE has a 430 W power supply for example which is connected with the main power connector (20 +4) pin and support (CPU) connector 4 pin. This same body, but without the power supply is designated VE2000SWA. From the collected system blocks of primary interest to us is the system unit with a water cooling system, and consider it in detail. For the installation of a water system used a standard kit, which is part of the body ThermalTake VE2430SWAE.

The order of assembly cooling followed. To set the processor to the motherboard through the universal set of fixed waterblock. Instructions for installing water block is described in detail in the description of the case. This phase of work requires special care. Waterblock tightened to a processor with four nuts through a metal pad. C on the one hand, it is necessary to ensure adequate contact with the CPU waterblock, on the other hand, it is important not to pull the nuts, but we can and "stone" to split the cost of several hundred American rubles. After installing the waterblock motherboard is placed in the housing and connected to it all interface cables. After that, the bottom of the hull assembly is installed from the storage tank and water pump. The assembly is attached to the bottom with screws through existing holes in the bottom. In front of the case has already been installed at the factory radiator blown by two 120mm fans.

Blocks of the cooling system are connected through polyethylene tubing. The tubes must be connected in a certain order: from the pump to the waterblock, water block on to the radiator from the radiator to the reserve tank. When connecting the tubes to make sure that they are not formed excesses obstruct the current fluid. To ensure the tightness of joints connecting pipes with blocks of the cooling system uses a simple but very effective and technically elegant solution. On the blocks are connecting fittings with thread, with some fitting is made in the form of a cone, which is put on the tube. Then screwed into the socket pre-worn to the tube nut, which is the reciprocal cone. When tightening the nut tapered surface of the nut and fitting converge and grip the pipe. Even a simple tightening the nut by hand provides sufficient tightness of the joint. You do not have any gaskets and clamps.

Precautions :

Apply a thin layer of thermal paste onto the cores or "cores" of those elements that go to cool, after which will place the blocks by their anchoring systems. When installing a hard disk cooling bay need to have a 5'25 "(the CD) free to ride there because these systems require to be installed. Once all the blocks mounted mount the computer normally and we can start with the circuit assembly with tubes that we have chosen for this work. Make sure you have all joints secure well before proceeding to fill the circuit. To this are recommended clamps on the fittings of the blocks to pull the tubes.

To complete the circuit we have two methods, the most recommended way is through the tank, allowing the water fills the circuit. The other is through a T-shaped adapter completing the circuit through it. After the initial filling should be allowed to run the circuit and refill if vacated, leaving the circuit operate eliminate air bubbles that may have. One of the greatest precautions to take is to ride the whole circuit out of the PC before mounting it. Here we see that the circuit is completely sealed, which lacks any type of leak as this could destroy our team. Another caution we have to choose materials, not just to save four dollars going to put our team in danger, no? If you have to pay anything more for a good material to do so without hesitation.

The Aircooling is a victim of its own principle: the fans are the cause of most of the drawbacks of this system. They tend to be noisy home and throughout their fouling associated with dust they can quickly become unbearable because of their excess decibels. To avoid these nuisances, the coolers require a fairly regular maintenance to maintain good performance.

Clean fan blades and all the radiator fins to prevent the accumulation of dust which reduces the cooling power. Connect your fans potentiometers or order to control their speed and thus able to regulate noise pollution. In the optimization of the use of airflow, cable management is very important not to disturb these flows and fans: therefore prefer round cables in large sheets and attach them to prevent them from coming to caught in the blades of different fans.

Put your fans by sources of heat, taking care to always be able to extract the hot air blown above inside the tower. The system will suit you perfectly Aircooling under moderate use your computer without overclocking. It offers a wide choice of products, however, not to be mistaken in his choice to see the conclusion on the system for Fan Less choice of the radiator. For the fan is either already fixed on the radiator or sold separately. If you have enough space of course prefer a diameter of 12 cm, the standard norm is 8cm. Also make sure that the cooler is compatible with your socket. A Cooler socket 754 will of course not adaptable to a 775.
