CPU fan, a key component in many PC systems, needs to be designed and optimised with consideration to cooling effect, noise control and energy saving.

First of all, CPU fans undoubtedly play an important role in protecting the stable operation of the CPU, prolonging the life of the hardware and improving system performance. With the development of science and technology, the design of CPU fan will be more efficient and intelligent, which can better adapt to the growing demand for heat dissipation and ensure the stable operation of the system for a long time.CPU fan will keep the CPU temperature within the safe range by generating wind power through the rotation of the blades, and the heat sink will take away the heat, which will further improve the performance of the system.

At the same time, system performance is also affected by the speed of the CPU fan. High-end CPU fans are usually equipped with an intelligent control system that can sense the CPU temperature through a temperature sensor and automatically adjust the fan speed according to the temperature to maximise the cooling effect. Some low-end CPU fans may not have such an intelligent control system, and therefore may not dissipate enough heat during operation, thus affecting system performance.

In addition, the noise of the CPU fan will also have an impact on system performance. Some high-end CPU fans have a four-wire design with closed-loop control of temperature and speed, which improves cooling efficiency, reduces power consumption of the host, and also reduces the noise when the fan is rotating. On the other hand, some low-end CPU fans may adopt a two-wire or three-wire design, which is noisier and may have an impact on the user experience, thus affecting system performance.

Therefore, the selection and use of CPU fan is very important for system performance. When purchasing a CPU fan, attention should be paid to brand reputation and after-sales service to ensure the quality and stability of the fan. At the same time, the correct use and regular maintenance of CPU fans can protect the normal operation of the computer and extend the service life of the hardware.
