Abstract
A method of operating a fan of a computing system includes: measuring a temperature of a subcomponent of the computing system; and comparing the temperature to a temperature threshold. When the temperature is greater or equal to than the temperature threshold, the fan is controlled based on a predetermined table of fan level settings. When the temperature less than the temperature threshold, a fan speed of the fan is measured. When the fan speed is not equal to zero, the method returns to the measurement of the temperature. When the fan speed is equal to zero, the fan is controlled based on a first power determination. The first power determination includes: measuring a system power level; and comparing the system power level to a trigger threshold. When the system power level is greater than the trigger threshold, the fan is activated to a predetermined setting.
