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.
