Abstract:
An electronic device includes a fan and a control device for controlling the fan. The control device includes a control unit, a first signal generation unit and a second signal generation unit each connected to the fan. The control unit has a first signal output terminal and a second signal output terminal. In use, the control unit first enables the first signal output terminal to generate a speed adjusting signal to control the fan. The control unit further detects whether a speed measurement signal is received from the fan, and enables the second signal output terminal to generate the speed adjusting signal to control the fan, if no speed measurement signal is received.
