Claim 2:
3. The information handling system of claim 1, where the information handling system comprises multiple cooling fans that are each configured to operate at multiple rotational speeds to draw cooling air into the enclosed interior of the chassis enclosure through the cooling air inlets from an atmosphere surrounding an outside of the external walls of the chassis enclosure and to circulate the cooling air from the cooling air inlets to the cooling air outlets to provide different flow rates of the cooling air through the enclosed interior of the chassis enclosure to cool the one or more heat-producing components within the enclosed interior of the chassis enclosure; where the at least one programmable integrated circuit is coupled to each of the multiple cooling fans; and where the programmable integrated circuit is programmed to perform the following when all of the multiple cooling fans are simultaneously operating together at the same common current real time rotational speed:
determine the common current real time rotational speed at which all of the multiple cooling fans is operating and a current real time total value of electric power consumed together by all of the multiple cooling fans;
determine a total 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 all of the multiple cooling fans operating together as a function of the determined current real time total value of electric power consumed together by all of the multiple cooling fans and the determined common current rotational speed of all of the multiple cooling fans.
