How to install the fans in the computer case


Each processor, especially the modern one, needs active cooling. Now the most popular and reliable solution is to install a processor cooler on the motherboard. They come in different sizes and, accordingly, different capacities, consuming a certain amount of energy. In this article we will not go into details, but consider mounting and removing the processor cooler from the system board.

How to install a cooler on a processor

During the assembly of your system, there is a need to install a processor cooler, and if you need to perform a CPU replacement, then cooling must be removed. There is nothing complicated in these tasks, you just need to follow the instructions and do everything carefully so as not to damage the components. Let's take a closer look at installing and removing coolers.

AMD cooler installation

AMD coolers are equipped with a kind of mount, respectively, the mounting process is also slightly different from others. It is easy to implement, it takes only a few simple steps:

    First you need to install the processor. There is nothing complicated about it, just consider the location of the keys and do everything carefully. In addition, pay attention to other accessories, such as connectors for RAM or a video card. It is important that after installing the cooling all these parts can be easily installed in the slots. If the cooler interferes with this, then it is better to install the parts in advance, and then already start mounting the cooling.

The processor, purchased in the boxed version, already has a proprietary cooler in the kit. Carefully remove it from the box without touching the bottom, because thermal grease has already been applied there. Install the cooling on the motherboard in the appropriate holes.

  • Cooling requires power for operation, so you need to connect the wires. On the motherboard, find the connector with the signature "CPU_FAN" and connect. Before this, position the wire conveniently so that the blades do not catch it during operation.
  • Installing a cooler from Intel

    The boxed version of the Intel processor comes with proprietary cooling. The mounting method is slightly different from the one discussed above, but there is no cardinal difference. These coolers are mounted on latches in special grooves on the motherboard. Simply select the appropriate location and insert the pins into the connectors one by one until you hear a click.

    It remains to connect the power, as described above. Please note that Intel coolers also have thermal grease, so unpack carefully.

    Installation of a tower cooler

    If the standard cooling capacity is not enough to ensure the normal operation of the CPU, you will need to install a tower cooler. Usually they are more powerful due to large fans and the presence of several heat pipes. Installation of such a part is required only for the sake of a powerful and expensive processor. Let's take a closer look at the steps for mounting a tower processor cooler:

    1. Unpack the box with refrigeration, and follow the attached instructions to collect the base, if necessary. Carefully read the characteristics and dimensions of the part before buying it, so that it not only fits on the motherboard, but also fits in the case.
    2. Fasten the back wall to the underside of the motherboard by installing it in the corresponding mounting holes.

    Install the processor and drip a little thermal paste on it. Smearing it is not necessary, as it is evenly distributed under the weight of the cooler.

    Attach the base to the motherboard. Each model can be attached in different ways, so it is better to turn to the instructions for help if something does not work out.

  • It remains to attach the fan and connect the power. Pay attention to the applied markers - they show the direction of air flow. It should be directed towards the back of the enclosure.
  • This completes the process of mounting a tower cooler. Once again, we recommend that you study the design of the motherboard and install all the parts in such a way that they do not interfere when trying to mount other components.

    How to remove a CPU cooler

    If you need to repair, replace the processor or apply a new thermal grease, you must always remove the installed cooling first. This task is very simple - the user must unscrew the screws or loosen the pins. Before that, it is necessary to disconnect the system unit from the power supply and pull out the CPU_FAN cord. Read more about dismantling the processor cooler in our article.

    Today we examined in detail the topic of mounting and removing the processor cooler on latches or screws from the motherboard. Following the above instructions, you can easily perform all the actions yourself, it is important only to do everything carefully and accurately.

    Typical air cooling for a computer

    The most common and cheapest cooling system used in computers is air, which works with the help of special fans. To better heat dissipation and increase the heat sink surface, metal radiators are placed on the most important parts. They remove a lot of heat, but their area is limited, so fans are additionally used. For example, it is on the main processor, in addition to the heatsink, since this is one of the most important and hottest microcircuits. For the best effect, at least one additional cooler should be installed in the system unit, which will create a constant air circulation and bring hot out. In most computers, especially in the minimal configuration - the so-called office version, no additional cooling is installed. However, in such models there is still one cooler - in the power supply, which is located at the top of the computer. Warm air, rising up from the motherboard and additional devices, is blown out with its help. But this design has disadvantages:

    • All warm air goes through the power supply, which itself is not slightly heated, which is why its parts overheat even faster. Therefore, it crashes most often.
    • A reduced pressure is created in the computer case, and to equalize it, air enters inside from anywhere - through all the cracks. Therefore, a lot of dust accumulates quickly inside, further deteriorating heat dissipation.
    • The created stream is not particularly stable, again, due to its influx from all possible openings. Unnecessary and harmful twists are created that greatly reduce the efficiency of the entire system.
    • The air flow is not very strong, for low-lying devices, such as a video card, is clearly insufficient.

    Therefore, the installation of additional coolers in the system unit is required. They are inexpensive and you can put them on your own.

    How to install fans in a computer case

    Installation of coolers in the system unit is carried out according to different schemes. Before you begin, you should definitely familiarize yourself with them, since the incorrect location of these nodes can do even more harm than their absence. Typically, the motherboard has a pair of connectors for cooling. They can be used both or only one. The fan installation diagrams in the computer case will then be as follows:

    1. On the back wall above, opposite the processor.
    2. On the front wall.
    3. The use of two fans - front and rear.

    You can choose any of these options, but the most preferred is the latter. Note that using only one cooler somehow upsets the air balance in a closed system. Therefore, we consider each option individually.

    Rear Location

    The fan installed at the rear should work by blowing, that is, remove warm air to the outside. In this case, the warm air flow no longer goes through the power supply and does not cause it to overheat. In addition, improved cooling of the processor. This option has a drawback - sparseness is created in the housing, and the air flow through various openings in the housing brings a lot of dust. However, the use of such a scheme still significantly improves the situation.

    Location on the front wall

    This fan should be located in the lower part, preferably opposite the hard drive, and work on blowing. It not only cools the hard drive directly, but also helps to equalize the pressure inside the case. The flow naturally goes from bottom to top, flowing around all the important nodes and blowing hot from the top out.

    Double option

    Installing a pair of fans in a computer case is the best option. One of them should stand under the power supply on the back wall and work on blowing. The second is frontal, mounted on the front wall, and works by blowing. This is the most correct arrangement of coolers in the system unit, as it creates a good air flow past all nodes. A big plus - the balance of internal pressure does not allow dust to accumulate inside the case. But everything will work fine only if a couple of rules are followed:

    • It is better to choose the maximum fan size for the installation site - if you can install a 140-mm model there, then put it, otherwise stop at the 120-mm version.
    • It is necessary to control where the fan should blow in the computer case. Front - blowing, rear - blowing. Otherwise, internal pressure and air circulation will be disturbed, and as a result there will be more harm than good.

    Main errors when installing the cooling

    It is important to know how to properly install coolers in the system unit. A malfunctioning cooling system may be ineffective, or, conversely, create conditions for rapid overheating. The most important thing here is which way the case cooler is blowing.

    • Only the rear blower is installed. At the same time, the warm air leaving the power supply unit immediately flows inward again and moves outward in the same circle. In the lower part of the casing, no circulation is created at all, and everything heats up there.
    • Only the front fan is installed, which operates on "blowing". So in the case low pressure will be created, and a lot of dust will quickly accumulate. Heat removal will not occur, so everything will overheat, and the computer will constantly keep coolers at maximum speed, so there will also be much more noise.
    • The rear cooler blows air, and the front cooler blows. This is not normal, if only because the warm air rises and its flow cannot be directed down. Therefore, the effect will be the same as in the previous paragraph.
    • Both coolers are blown in. Overpressure is created in the case, the fans work for wear, but, of course, there is no benefit.
    • Both coolers are blowing. This is the most dangerous situation, since a reduced pressure is created in the case, air circulation is disturbed, and all computer components overheat very quickly.

    As you can see, it is very important which side the cooler is installed on. Once he is turned over, he will begin to blow in the wrong direction. Therefore, this should always be checked. The correct installation of fans in the PC case - the upper back should blow air, and the lower front should blow. Then its circulation will be natural and correct, and the cooling system will work as efficiently as possible. Now you know how to install cooling coolers in the system unit. If you installed them yourself, check their work. If you are just going to do it, do it right right away.
