Abstract
In a method for adjusting a fan of an electronic device, a sensor of the electronic device detects an instant work environment temperature of an electronic component of the electronic device. The detected temperature is obtained from the sensor. The speed of the fan under the detected temperature and a speed of the fan to which it may be adjusted is computed using a predefined algorithm based on prestored values, obtained from experimentation. The fan is adjusted to achieve a heat dissipation mode and an energy-saving mode of the electronic device accordingly.
