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.

Abstract: A fan failure backup apparatus includes a first fan module and a second fan module. When a second control unit of the second fan module realizes that the first fan module is failed through a first control unit of the first fan module, and the second control unit realizes that the second fan module is not failed, the second control unit controls the second fan module to additionally enhance a pressure-flow characteristic of a second fan unit of the second fan module.
