Abstract

A system may include a plurality of temperature sensors configured to sense temperatures at a plurality of locations associated with an information handling system, a cooling subsystem comprising at least one cooling fan configured to generate a cooling airflow in the information handling system, and a thermal manager communicatively coupled to the plurality of temperature sensors and the cooling subsystem. The thermal manager may be configured to, based on at least a power provided to a subsystem of the information handling system, estimate a thermal condition proximate to the subsystem, correlate each of a plurality of components of the subsystem and a linear airflow velocity requirement of the component to a respective speed of the at least one cooling fan required to provide such airflow requirement, and set a speed of the at least one cooling fan based on the respective speeds.

A system comprising:

a plurality of temperature sensors configured to sense temperatures at a plurality of locations associated with an information handling system;
a cooling subsystem comprising at least one cooling fan configured to generate a cooling airflow in the information handling system;
and
a thermal manager communicatively coupled to the plurality of temperature sensors and the cooling subsystem and configured to:
based on at least a power provided to a subsystem of the information handling system, estimate a thermal condition proximate to the subsystem;
correlate each of a plurality of components of the subsystem and a linear airflow velocity requirement of the component to a respective speed of the at least one cooling fan required to provide said linear airflow velocity requirement;
