Abstract
A fan control system and a method thereof are applicable to a computer device. The system includes a fan, a board management unit, a power control module and a rotation speed switching module. The fan is driven by a control power and a rotation speed control signal. The board management unit provides a fan enabling signal, a rotation speed switching signal and a first fan rotation speed signal in a standby state. The power control module receives the fan enabling signal to determine whether to provide the control power to the fan, and switches between an auxiliary power or a main power served as the control power to the fan. The rotation speed switching module receives the rotation speed switching signal to accordingly switch between the first fan rotation speed signal or a second fan rotation speed signal served as the rotation speed control signal to the fan.
