Abstract
A method for controlling fans arranged in different working areas comprises: presetting a plurality of fan operation frequencies, receiving a fan operation request and adjusting a frequency of a pulse width modulation (PWM) controller to a first objective frequency based on the fan operation request, and sending the first objective frequency to the fans arranged in different working areas, to drive a first fan arranged in a first objective working area to run. Each of the plurality of fan operation frequencies corresponds to different working areas, the first objective frequency is one of the plurality of fan operation frequencies, and the first objective working area is one of the plurality of working areas corresponding to the first objective frequency. A system for controlling fans and an electronic device are also disclosed.
