摘要： A heat dissipation device comprises a fan motor, a drive circuit, and a reset current reduction circuit. When the fan motor is locked, an input terminal of the reset current reduction circuit receives an alarm signal, and an output terminal thereof outputs a voltage signal, which is larger than a reference voltage generated as the fan motor is at a low rotation rate, so as to decrease a reset current of the fan motor.
