Classification: CPC F  G  H  Y | IPC F

Claim 5:
6. A fan control method, comprising:
continuously sensing temperatures of a device during a time period to obtain a plurality of sampled temperatures;
selecting N1 latest sampled temperatures and N2 latest sampled temperatures from the sampled temperatures, and calculating a first average temperature according to the N1 sampled temperatures and a second average temperature according to the N2 sampled temperatures, wherein N1 and N2 are positive integers, the positive integer N1 is greater than 0, and the positive integer N2 is greater than the positive integer N1;
selecting one of the first average temperature and the second average temperature according to one of a plurality of determination modes to output as a compensation temperature, wherein the determination modes comprise:
(a) selecting the first average temperature;
(b) selecting the second average temperature;
(c) selecting a larger one of the first average temperature and the second average temperature; and
(d) selecting a smaller one of the first average temperature and the second average temperature; and
adjusting a rotational speed of a fan according to the compensation temperature.
