Abstract
A fan control circuit for controlling a fan includes a processing module, a driving module and a speed compensation module. The driving module is electrically connected to the processing module, and generates at least one driving signal to drive the fan. The speed compensation module is electrically connected to the processing module, and receives a first voltage. The first voltage is variable. The speed compensation module generates and transmits a speed-compensation parameter to the processing module according to the first voltage and a first waveform, and the processing module adjusts the driving signal according to the speed-compensation parameter.
