Abstract

A fan control device, which receives an exterior starting signal, includes a rotation speed controlling module and a driving module. The rotation speed controlling module receives the starting signal and produces an initial rotation speed controlling signal according to the starting signal. After a particular period, the rotation speed controlling module produces a rotation speed controlling signal. The driving module receives the initial rotation speed controlling signal and controls the fan to reach an initial rotation speed according to the initial rotation speed controlling signal. Then, the driving module receives the rotation speed controlling signal and controls the fan to reach a rotation speed according to the rotation speed controlling signal. In addition, a fan control method, which is applied to the fan control device, is also provided.
