How to choose the right fan for your PC?

The fan is an important element in a computer, it helps to avoid overheating of your components and to cool your PC. The processor and the graphic card are components that are particularly hot, so it is mandatory to equip them with fans or ventirads (for the processor). For more cooling, you can also equip your case with fans. Everything is explained.

Which fan to choose for my processor?

You want to cool your processor more efficiently or replace a fan that is not very efficient or too noisy? Here are the tracks to help you make the right choice. First of all, you need to know your current configuration and your computer's processor. Indeed, fans are designed to fit a socket. So remember to check the compatibility with your motherboard. The dimensions of the fan, especially its diameter is an important element. Be aware that the larger the model, the more interesting it will be in terms of cooling, it is also likely to make less noise. Another element to look at is the material used for the radiator part of the fan. Prefer copper because it conducts heat better than aluminium. On the other hand, it will also be more expensive... Knowing that the fans often weigh quite heavy and/or are equipped with a fixing system that can deform the motherboard, do not hesitate to check again that the motherboard can support it. Also pay attention to the space around the socket if you want to install a large heatsink or fan. For users looking for a quiet fan, it is preferable to choose a model running at 800 rpm. For those looking for cooling performance, such as gamers, choose a faster fan, above 800 rpm.

How do I choose a fan for my graphics card?

As always, be sure to check the compatibility and space around your graphics card slot. There are various models of graphics cards, equipped with several fans, the number varies as well as the size of each one. These are important criteria, because a model with two 6 cm fans will be much noisier and not necessarily more efficient than a model with a single 8 cm fan for example. We also find the same principle as for the processor. On the radiator side, always prefer copper for the same reasons mentioned above. If the model benefits from heat pipes, it is even better since it allows a better heat dissipation, especially if these are associated with an efficient ventilation. A very important point for the graphics card: the cooling device of the fans must be self-regulating. This means that the speed of the fans must automatically adapt to the heat emitted by the graphics card, depending on its temperature.

For optimal cooling, install fans on your case.

The most concerned by the reinforcement of the cooling system are graphic design enthusiasts and gamers who use power-hungry computers and therefore need optimal cooling! For them, it is therefore advisable to opt for a model offering a high airflow, at least 70 CFM, but don't expect silence. For those who, on the contrary, simply want an air device but silent, make sure that the fans chosen offer a noise level of less than 20 dB. Be aware that 12 cm fans are the most common models, but check the dimensions of the slots you have on your case. Indeed, this can vary and go up to 20 cm in diameter. Last tip: prefer the vertical position for your fans in your tower. Indeed, the horizontal position tends to sag and become noisier. You now have all the cards in hand to choose the right fans for your desktop.
