SYSTEMS AND METHODS FOR THERMAL MANAGEMENT OF AN INFORMATION HANDLING SYSTEM USING ESTIMATES OF LINEAR AIRFLOW VELOCITY BASED ON CUBIC FLOW RATE AND AIRFLOW AREA

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 and set a speed of the at least one cooling fan based on the estimated thermal condition and a required cubic airflow rate associated with the subsystem, wherein the required cubic airflow rate is determined based on a required linear airflow velocity associated with the subsystem and a net cross-sectional area through which the cooling airflow travels.
