Heat dissipation system for computers

A heat dissipation method for a computer comprising:

• obtaining a measurement temperature of a computer by a temperature sensor;
• changing a rotation speed of a heat dissipating fan in a stepwise manner by one step based on a threshold temperature and a measurement temperature measured by said temperature sensor;
• determining whether or not said measurement temperature has exceeded said threshold temperature in a predetermined period of time, wherein said determining further includes determining a prediction temperature and a prediction time required for said measurement temperature to exceed said threshold temperature when current processing capability of a processor is maintained, based on said measurement temperature, an increase rate of said measurement temperature, and said threshold temperature;
• and
• in response to a determination that said measurement temperature has exceeded said threshold temperature, temporarily reducing the processing capability of a processor within said computer based on said prediction time changing said prediction temperature to a new prediction temperature based on an updated utilization rate of said processor.
