Description

technical field [0001] The present application relates to the field of artificial intelligence, and in particular, to a fan control method and system. Background technique [0002] The fan rotates at a certain speed to effectively dissipate heat to the server and other machine systems. In the prior art, when using a fan for heat dissipation, the fan is usually connected to a power supply with a controllable voltage, and then the power supply voltage is manually adjusted to correspondingly adjust the fan speed to increase or decrease. Subjective analysis is carried out based on historical adjustment experience, and the voltage adjustment range is determined and manually set, resulting in inaccurate and inaccurate voltage adjustment, which further leads to the problem of low fan speed control accuracy and inability to quantify fan speed control. In the fan development stage, the air volume, noise and heat dissipation effect under a specific fan speed condition are determined ...
