Everyone who has used fan products knows that after using them for a period of time, they will produce noise. In order to solve this problem well, we need to consider and analyze it from its origin.

Reason 1: Temperature rise

After the temperature rises, the temperature difference decreases, and the heat dissipation effect is also reduced.

Reason two: the influence of fan speed and size

The fan's speed is happy to dissipate heat, the larger the size, the greater the air volume, and the better the heat dissipation effect. However, the larger the fan's speed, the greater the noise, and the larger the size, the greater the noise.

Reason three: the impedance of the system

Air flow resistance will also cause flow noise in the air.

Reason four: flocculation of airflow

Due to the poor design of the flow channel, the flocculation of the air will produce higher noise. If the flow channel cannot be improved, it is difficult to effectively improve it.

The main reasons for the noise caused by turning off the fan are the above reasons. In order to avoid this situation, you can solve the above reasons.
