Patent ID: 8171314

Claim:
An information handling system comprising: a housing; a CPU disposed in the housing and operable to process information; memory disposed in the housing and interfaced with the CPU, the memory operable to store information; one or more thermal measurement devices disposed in the housing and operable to measure one or more thermal parameters; a management processor disposed in the housing and interfaced with the thermal measurement devices, the management processor operable to perform one or more management functions; one or more system cooling fans interfaced with the management processor and operable to generate a cooling airflow in the housing; a system thermal manager running on the management processor and operable to apply the thermal parameters to operate the system cooling fan at a selected speed; and a power supply disposed in the housing and operable to power at least the CPU, the power supply having a cooling fan and a thermal manager, the power supply thermal manager interfaced with the system thermal manager and operable to run the power supply cooling fan at a selected of a speed determined locally at the power supply or a speed determined distally at the system thermal manager; wherein the system thermal manager is further operable to load thermal management parameters to the power supply thermal manager that define the locally determined power supply fan speed.
