Abstract
A method for controlling a fan speed is disclosed. The fan cools a CPU in a computer. The method includes defining a CPU-max-temp value of a CPU, such that the first fan speed is linearly enhanced with the increase of a real temperature value of the CPU, when the real temperature value of the CPU is lower than the CPU-max-temp value, and changing the CPU-max-temp value to a higher CPU-max-temp value in a basic input output system. A second fan speed is linearly enhanced with an increase of the real temperature value, when the real temperature value is lower than the higher CPU-max-temp value. The second fan speed is less than the first fan speed at the real temperature value.
