Title
(EN) A fan control method, a fan control device, and an electronic device
(ZH) 风扇的控制方法、风扇控制装置及电子设备
Abstract
(EN)
A fan control method, a control device, and an electronic device are provided. The fan control method is applied to a system including a fan and multiple heat source modules, and includes: obtaining the temperature corresponding to multiple heat source modules (201); determining the control temperature based on the temperatures corresponding to multiple heat source modules (202); determining a control signal for the fan according to the control temperature so as to control the fan to run at a certain speed (203). By collecting the temperature of multiple heat sources, the fan speed can be accurately controlled to meet the heat dissipation requirements of multiple heat source modules.
