Which side of the fan should go on the processor

Cooling your computer’s CPU and graphics cards

To understand how a cooling system works, let’s remember physics. There is no such thing as “cold”, it is relative and cannot be changed. There’s the concept of heat. any part of a computer that consumes energy gives off heat. Everything around us has a certain heat charge that is constantly being transferred from more to less.

This is a very simplified explanation. But now we know that the air that passes through a radiator doesn’t cool it, it just takes heat on itself. There’s also the thermal conductivity and the heat capacity of materials. Heat sinks are made from the most thermally conductive materials with the least heat capacity. The point is that they can quickly absorb heat and quickly give it away without accumulating this energy.

The same principle applies to graphics card cooling. But because of the large number of manufacturers and the special shape of this component, the radiators are all different and are made to fit a specific video card model, while CPU radiators are standardized.

Some heavily loaded motherboard elements such as power supply circuit or chipset are equipped with fanless heatsinks. If your system involves overclocking, using a powerful graphics card and CPU, then you need good airflow through the case. Then a flow of fresh air will cool all elements with a passive cooling system.

Which way the fan on the graphics card heatsink should blow

The cooler (fan) on the CPU or graphics card is for local cooling of a specific item. So the general air circulation in your case is not taken into account here. The fan on the cooler must blow air through the heatsink, thereby cooling it. That is, the fan on the cooler on the processor must blow toward the processor (blow through the heat sink!).

On some models of coolers, the fan is mounted on a separate heatsink. In this case, it is better to place it so that the air flow is directed towards the back of the case or upwards towards the power supply.

On simple graphics cards the cooler blows air from the top to the inside of the graphics card heatsink. Most high-performance graphics cards have a cooler that consists of a heatsink and impeller and blows it in a circular pattern. In this case air is sucked in through one half of the radiator and blown out through the other half.

On some models of coolers, the fan is mounted on a separate heatsink. In this case, it is better to place it so that the air flow is directed to the side of the rear wall of the case or up toward the power supply.

On simple graphics cards the cooler blows air from the top to the inside of the graphics card radiator. On most powerful graphics cards, the cooler is a radiator and impeller and blows it in a circle. In this case, one half of the cooler draws air in and the other half blows air out.

This is how you should mount your CPU cooler! I think??

How to determine which side to put the cooler on the CPU?

The fan on the cooler should blow air through the heatsink, thereby cooling it. That is, the fan on the CPU cooler should blow toward the CPU.

To cool the entire room, it is better to install ceiling fans, they increase air circulation and it becomes easier to live. Floor fan is usually quite large and can also refresh the whole room. It’s best to put it in the middle of the room or near an open window so the hot air can cool right off.

How many fans should be in an enclosure?

To answer the question posed in the title of this text, it is safe to say that in the case of gaming computers you should have at least four fans. two mounted on the front and two on the back. On the other hand if you have a case with a peorized top it is worth adding one or two fans on top.

The fan at the back should be blowing, which means that the warm air is blowing outward. This prevents warm air from blowing through the PSU and causing it to overheat. Also the processor cooling is improved.

Which way the case fans should spin?

Ideally, cool air should be drawn in from the bottom to the front of the case. This part quickly becomes clogged with dust and needs to be cleaned with a vacuum cleaner.

Hot air blowing out the top and back and through the power supply. Take air direction into consideration when installing fans. Otherwise, you might make it worse for cooling.

Correct airflow direction

Hard drives are usually placed at the bottom. The fan in front must blow air in.

Some cases have a fan on the side cover. Then it must spin in such a way that it draws air in and additionally cools the CPU and motherboard.

The manufacturer always puts arrows on the case of the cooler indicating the direction of airflow. Follow them when installing.

How many fans you can install on one connector?

4-pin Molex connector ATX12V (also called P4 power connector), which is also a plug and socket, allows you to connect in parallel an unlimited number of devices. The power of such devices is small. So if you want you can install all the case fans on one socket.

Also there are splitters on sale. For example, from a 4-pin Molex to 4 fans with a 3-pin connector. Pay attention to the color: white. 12V, black. 5V.

The 3-pin and 4-pin jacks have restrictions. If you do not do homemade, and use the factory connectors, one connector on the motherboard allows you to connect a single fan. With the splitter you can increase the number, but I would not put more than two fans in one slot.

How to install the fans in a computer case

Installation of coolers in the system unit is made according to different schemes. Be sure to familiarize yourself with them before you start, because the wrong location of these nodes can cause even more damage than their absence. Usually on the motherboard there are a couple of connectors for cooling. You can use both of them or just one. Schemes of installation of fans in the computer case then will be as follows:

You can choose any of these options, but the last one is the most preferable. Note that using only one cooler somehow disturbs the air balance in a closed system. So let’s consider each option separately.

How to remove the CPU cooler

If you need to make repairs, replace the processor or apply a new thermopaste, it is always first necessary to remove the installed cooling. This task is very simple. the user must remove the screws or unfasten the pins. Before this, you must disconnect the system unit from the power supply and pull the CPU_FAN cord. Read more about removing the CPU cooler in our article.

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