Zusammenfassung:	A method for controlling operation of a fan in an information handling system using a single parameter includes measuring a temperature associated with the information handling system, determining an average power load of the information handling system, determining a ratio based on the average power load, a light power load and a heavy power load, calculating a single parameter based on the measured temperature and the ratio, determining an operating fan speed based on the single parameter and signaling a fan to operate at the operating fan speed. The ratio may be difference between the average power load and the light power load divided by a difference between a heavy power load minus the light power load. Determining an operating fan speed may include applying one or more constants to the ratio.
