Temperature trend controlled cooling system
An information handling system (IHS) temperature control system includes a cooling system, a controller coupled to the cooling system, and an IHS coupled to the controller. The IHS includes a temperature status reporting engine that is configured to determine a first temperature of the IHS and determine a second temperature of the IHS subsequent to determining the first temperature. In response to the second temperature being above a first predetermined temperature range, the temperature status reporting engine provides a first signal to the controller to increase cooling provided by the cooling system if the first temperature and the second temperature indicate that a temperature trend of the IHS is not decreasing, and provides a second signal to the controller to maintain cooling provided by the cooling system if the first temperature and the second temperature indicate that the temperature trend of the IHS is decreasing.
