Abstract
Disclosed herein are systems and methods that may be implemented in real time to determine the total volumetric rate of airflow through a chassis enclosure of an information handling system platform directly from real time measured cooling fan power consumption in combination with standalone or system-level cooling fan power characteristics (e.g., expressed as cooling fan power curves) that relate cooling fan volumetric airflow rate to cooling fan power consumption at the current fan rotation speed. This determined value of total real time volumetric airflow rate may then be used, for example, by individual system level thermal control algorithms and/or data center level thermal control algorithms.
