Abstract:
A rotational speed control system includes a fan controller and a fan controlling circuit. The fan controlling circuit is coupled to the fan controller. The fan controlling circuit can receive a rotational speed control signal and output a fan driving signal to the fan controller. The fan driving signal is a regulated high level voltage signal. The fan controller can adjust rotational speed of the fan according to the driving signal.
