Abstract
An approach is provided in which a cooling manager retrieves pre-characterization data corresponding to a fan that electronic components included in a computer system. The pre-characterization data includes operational zones based upon fan power measurements and fan speed settings. The cooling manager sets the fan to a first speed setting within a first operational zone, and detects that one of the components generates a temperature change value that exceeds a specified temperature change value corresponding to the component. In turn, the cooling manager selects a second operational zone and sets the fan to a second speed setting within the second operational zone.
