Assignee: DELL PRODUCTS L.P.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 3:
4. The information handling system of claim 1, further comprising non-volatile memory (NVM) coupled to the at least one programmable integrated circuit, the NVM storing multiple relationships between values of electric power consumption of the at least one cooling fan and values of volumetric airflow rate provided by the at least one cooling fan, each of the multiple relationships being defined for a different rotational speed of the at least one cooling fan; and where the at least one programmable integrated circuit is programmed to:
retrieve one of the stored relationships from the NVM that corresponds to the determined current rotational speed of the at least one cooling fan; and
determine the current real time volumetric airflow rate of the cooling air circulated from the cooling air inlets to the cooling air outlets through the enclosed interior of the chassis enclosure by the at least one cooling fan to be a volumetric airflow rate value from the retrieved relationship that corresponds to the determined current real time value of electric power consumption of the at least one cooling fan.
