1. A fan module, comprising:
a fan having an air inlet;
a baffle disposed at the air inlet of the fan, adapted to expose or shield the air inlet;
an electromagnet electrically connected to the fan;
a ferromagnetic slider disposed between the electromagnet and the fan and capable of moving between the electromagnet and the fan; and
a first connector connected between the ferromagnetic slider and the baffle so that the ferromagnetic slider is linked to the baffle,
wherein when the fan is functioning, the electromagnet attracts the ferromagnetic slider to drive the baffle to move to an open position to expose the air inlet, and when the fan is powered off, the electromagnet does not attract the ferromagnetic slider, the first connector drives the ferromagnetic slider away from the electromagnet, and the baffle moves to a shielding position to shield the air inlet.
