Abstract

The present invention relates to a complementary fan rotating speed control method and apparatus, which is used for monitoring the rotating speed of at least two fans simultaneously. A controller is applied to output a pulse width modulation (PWM) control power to operate a first fan and a second fan. Then, the rotating speed pulse signals of the first and second fans will be transmitted back to the controller. If the controller detects a reduction in the rotating speed of either the first fan or the second fan, the controller will increase the rotating speed of the other fan and transmit a warning signal to ensure the cooling effect and thus extend the service time of the apparatus.
