Systems and methods to determine and control temperature threshold for air-cooled expansion card devices

Disclosed herein are systems and methods of determining a maximum allowable air temperature limit for closed loop (CL) control of the inlet boundary or threshold temperature of a given computer expansion slot that contains a particular mating expansion card. The maximum allowable air temperature lim...

description Disclosed herein are systems and methods of determining a maximum allowable air temperature limit for closed loop (CL) control of the inlet boundary or threshold temperature of a given computer expansion slot that contains a particular mating expansion card. The maximum allowable air temperature limit may be determined for closed loop control of the expansion slot inlet boundary temperature by using reverse correlation of an open loop (OL) cooling tier curve that has been designated for open loop control of cooling air velocity provided to the particular expansion card of the given expansion slot. The reverse correlation may be performed in further view of the particular expansion slot airflow characteristics (e.g., maximum expansion slot airflow velocity capacity or limit) corresponding to a expansion card received in a given expansion slot.
