Power supply to provide operation power for cooling fans
A power supply to provide operation power for cooling fans includes a non-stop power system to provide DC power in normal conditions to a remote switch control circuit to set a computer in an ON or OFF condition. The non-stop power system also outputs the DC power to a fan actuation control circuit to drive a rear end cooling fan. The fan actuation control circuit and the remote switch control circuit are bridged by a cooling delay unit. The cooling delay unit receives a computer ON/OFF signal from the remote switch control circuit and outputs another signal to enable the cooling fan to operate for a period of time before stopping.
