Abstract
A system for compensating the characteristics of a fan, applied to a heat-dissipating fan of an electronic device. This system comprises of an analyzing module for analyzing the relation between the duty ratio of pulse width modulation (PWM) and the rotational speed of the fan to generate analyzing data, and a compensating module for generating compensating data basing on the analyzing data and a specific proportion relation between the temperature and the duty ratio of PWM.
