Fan module and control device thereof. The fan module comprises a plurality of fans and the control device. The control device comprises a temperature sensing circuit, and a driving circuit. The temperature sensing circuit detects an ambient temperature of the fans and generates a sensing signal accordingly. The driving circuit is coupled between the fans and temperature sensing circuit, and comprises a fully powered operating mode and a power-saving operating mode, wherein the driving circuit selects different operating modes in accordance with the sensing signal, and generates a fan driving signal controlling the speed of the fans.
