发明名称 Method and device for controlling a heat-dissipating fan for an electronic component
摘要 A method for controlling a heat-dissipating fan for an electronic component includes the steps of: detecting a temperature of the electronic component, and outputting a first control signal corresponding to the temperature thus detected; receiving a load current of the electronic component, and converting the load current into a second control signal; and controlling a rotating speed of the heat-dissipating fan with reference to the first control signal and the second control signal. A device employing the method includes a current detecting module adapted for detecting a load current, a temperature control circuit adapted for detecting a temperature, and a logic circuit unit coupled to the current detecting module and the temperature control circuit and controlling a rotating speed of a heat-dissipating fan.
