Abstract
The present invention relates to a method for auto-regulating the fan speed. The method includes detecting the temperature of a thermal source. When the temperature of the thermal source exceeds a target value, the fan speed of the fan is regulated according to a relation between the temperature of the thermal source and the fan speed of the fan. Thereafter, the voltage applied to the fan is micro-adjusted through a feedback control mechanism so that the fan speed of the fan reaches a specified speed in steps.
