Abstract
After a temperature point of the cooling fan is set according to a plurality of temperatures corresponding to a plurality of first consecutive time intervals, control a duty cycle of the cooling fan according to the temperature point, acquire temperature variation data of the cooling fan during a plurality of second consecutive time intervals, generate a gain factor and a frequency factor of the cooling fan according to the temperature variation data, and generate a proportional gain factor, an integral time factor and a derivative time factor of a proportional-integral-derivative controller of the cooling fan according to the gain factor and the frequency factor of the cooling fan. The plurality of first consecutive time intervals are followed by the plurality of second consecutive time intervals.
