Abstract
A control device of a fan system, which has at least one fan, receives a starting voltage. The control device includes a start controlling unit and a driving unit. The start controlling unit receives the starting voltage and outputs a start controlling signal according to the starting voltage. After a predetermined period, the start controlling unit stops sending the start controlling signal. The driving unit is electrically connected to the start controlling unit and the fan, respectively. The driving unit receives the start controlling signal for controlling the rotation speed of the fan.
