Abstract
A method for controlling an angular speed of a fan of a computer system includes obtaining an error value; obtaining an adjusted error value by adjusting the error value using an adjustment constant when an absolute value of the error value is not larger than a predetermined value; obtaining a total output value according to at least the adjusted error value; and controlling the angular speed of the fan according to the total output value. The total output value is positively related to a pulse width modulation value, and the angular speed of the fan increases when the pulse width modulation value increases.
