Abstract: An apparatus and a method for controlling a fan are disclosed. The apparatus comprises a subtractor, a decision unit, and an adjustment unit. The subtractor calculates a rotational speed difference between a current rotational speed and a target rotational speed. The decision unit decides an adjust factor according to the rotational speed difference. The adjustment unit changes a rotational speed control signal from a first control signal to a second control signal according to the adjust factor.
