Abstract
A fan module, especially a fan module which may reduce a rotating speed of a fan automatically when an object with static electricity gets into the fan is provided. The fan module includes a frame, a fan, an electrostatic induction unit and a controller. The fan is disposed in the frame, and the electrostatic induction unit is disposed on the frame and adjacent to the fan. The controller is electrically coupled to the electrostatic induction unit. When an object with static electricity gets into the electrostatic induction unit, the electrostatic induction unit outputs a sensing value to the controller. The controller determines whether to reduce the rotating speed of the fan according to the sensing value.
