Patent abstract
An electronic device with redundant fan control function includes a first fan, a first control module, a first power supply, a first switch unit, a second fan, a second control module, a second power supply, and a second switch unit. When the first power supply stops working, the second power supply powers the first fan and the second fan, and the first power supply sends a control signal to turn on the first switch unit to allow a group of control information output by the second control module to control the first fan. Therefore, the first fan and the second fan can work normally to dissipate heat from the electronic device.
