ABSTRACT:
A computer system includes a first heat generating element in which a heat generation amount is changed, a second heat generating element, a fan configured to cool the first and second heat generating elements, a first temperature sensor configured to detect a temperature of the first heat generating element, a second temperature sensor configured to detect a temperature of the second heat generating element, and a controller configured to control a rotation speed of the cooling fan, based on the temperatures detected by the first and second temperature sensors.
