A CPU fan, also known as a heatsink, is a key component in a computer's internal system and is typically mounted on the CPU cooler.The main purpose of a CPU fan is to carry away the heat generated by the CPU, preventing the CPU from becoming too hot and causing the system to malfunction or crash.

When choosing a CPU fan, several factors should be considered. Firstly, the CPU slot type and model number is a must know. Secondly, when choosing a CPU fan, you need to pay attention to its size and choose the appropriate size to meet the CPU cooling needs. Then, you need to pay attention to the noise control of the fan, generally the less noise the better. At the same time, when choosing a fan, you also need to consider its speed, the higher the speed, the better the cooling effect, but at the same time will produce more noise.

The power connector and fixing method of the CPU fan are also factors to consider. Generally speaking, the power connector of the CPU fan and the motherboard connector should match, and there should be a corresponding fixing method to ensure the stability of the CPU fan in the process of use.

Overall, choosing a suitable CPU fan requires comprehensive consideration of a number of factors, including CPU model, slot type, volume, noise control, speed, power connector and fixing method. Attention also needs to be paid to the cooling components and cooling method to ensure the cooling effect of the CPU and the stability of the system.
