Abstract: A heat dissipation apparatus with energy-saving effect is coupled to an operation unit, and the heat dissipation apparatus includes a control unit and a drive circuit. The control unit determines whether the operation unit enters an energy-saving mode according to a first signal provided by the operation unit. The control unit shields a plurality of second signals provided to the drive circuit according to the energy-saving mode. The drive circuit does not drive the heat dissipation unit and the heat dissipation unit enters an inertia deceleration.
