Abstract:
1. An information handling system comprising: an enclosure having an inlet and an outlet; plural components disposed in the enclosure and operable to cooperate to process information; a cooling fan disposed in the enclosure and operable to generate a cooling airflow from the inlet to the outlet with a selected of plural available fan speeds; a power supply operable to power the plural components; an inlet temperature sensor operable to sense airflow temperature at the inlet; and a thermal manager interfaced with the cooling fan, power supply and inlet temperature sensor, the thermal manager operable to apply power dissipated by the power supply to one or more of the components and the inlet airflow temperature to set a speed of the cooling fan that maintains a predetermined thermal state in the enclosure proximate the one or more of the components, the thermal manager further operable to determine that the plural available fan speeds will not maintain the predetermined thermal state and, in response, to select one or more components of the one or more components to power down to allow available fan speeds to maintain the predetermined thermal state, the selected component having a predetermined thermal profile.
