Disclosed are a device for controlling a heat dissipation fan and an electric equipment, to solve the problem that the reliability of speed-regulation control for a fan in the device for controlling a heat dissipation fan is relatively poor. The device includes a control system and a protection module, wherein the protection module includes a control signal output end for outputting a fan speed-regulation control signal to the fan, wherein, when a control system normal operation indication signal is normal, the control signal output end of the protection module outputs the fan speed-regulation control signal provided by the control system, otherwise the protection module outputs a fan speed-regulation control signal preset by itself so as to make the fan operate stably. Since the protection module outputs the fan speed-regulation control signal preset in the protection module to make the fan operate stably when the control system operates abnormally, the reliability of speed-regulation control for the fan is enhanced and the reliability and stability of the heat dissipation fan system are improved. |
