Abstract
A fan control method is to be implemented by a control circuit for controlling a fan coupled thereto. The fan control method includes configuring the control circuit to output a driving signal to the fan such that the fan rotates according to the driving signal, to detect a rotational speed of the fan and to generate a feedback signal corresponding to the rotational speed thus detected, to identify a model of the fan according to the feedback signal thus generated, and to control rotation of the fan according to the model thus identified.
