Abstract: A system for maintaining the operation of a cooling fan for a server if that function of a baseboard management controller (BMC) of the server should fail includes the BMC and a control module. The control module is electrically connected to the BMC and the fan, and the control module receives a first signal outputted by the BMC in a cycle and determines the state of the BMC depending on whether the first signal includes a change in level or fails to include a change in level. When an abnormal state of the BMC is determined, the control module outputs a preset pulse width modulation (PWM) signal to the fan to maintain operation of the fan.
