Abstract
A system of controlling fan speed includes a controlling device and a fan, which connects to the controlling device. The controlling device defines a plurality of fan speed ranges corresponding to different temperatures. A fan speed controlling method based on the system includes steps as follows: the controlling device detecting temperature and outputting a PWM signal to the fan; the fan outputting a fan speed signal to the controlling device; when the fan speed is within a predetermined fan speed range, the PWM signal keeping unchanged; when the fan speed isn't, the controlling device modulating the PWM signal until the fan speed is within the predetermined range.
