Heat dissipation system for computers
First Claim
1. A heat dissipation system within a housing of a computer, said heat dissipation system comprising:
- a heat dissipating fan;
a temperature sensor;
a rotation speed setting portion configured to change a rotation speed of said heat dissipating fan in a stepwise manner based on a threshold temperature and a measurement temperature measured by said temperature sensor; and
a performance control portion configured to temporarily reduce the processing capability of a processor within said computer in response to a determination that said measurement temperature has exceeded said threshold temperature during a predetermined period of time, wherein said performance control portion includes;
a temperature prediction portion configured to determine a prediction time required for said measurement temperature to exceed said threshold temperature when current processing capability is maintained, based on said measurement temperature, an increase rate of said measurement temperature, and said threshold temperature; and
a processing capability setting portion configured to change said processing capability of said processor based on said prediction time.

Abstract
A heat dissipation system within a housing of a computer is disclosed. The heat dissipation system includes a heat dissipating fan, a temperature sensor, a rotation speed setting portion, and a performance control portion. The rotation speed setting portion is configured to change a rotation speed of the heat dissipating fan in a stepwise manner based on a threshold temperature and a measurement temperature measured by the temperature sensor. The performance control portion is configured to temporarily reduce the processing capability of a processor within the computer in response to a determination that the measurement temperature has exceeded the threshold temperature during a predetermined period of time.
