Abstract
A method of controlling fan speed is provided. The method includes: setting a target speed of the fan; providing an actual control speed signal and using the actual control speed signal to drive the fan so as to obtain an actual speed of the fan; determining whether the actual speed of the fan is equal to the set target speed; and when the actual speed of the fan is equal to the set target speed, continuously using the provided actual control speed signal to drive the fan, otherwise, gradually compensating the intensity of the provided actual control speed signal until the actual speed of the fan is equal to the set target speed after the fan is driven by the gradually compensated actual control speed signal.
