Abstract:
A method for controlling a plurality of server chassis cooling fans, comprising:transmitting first and second requests to first and second server processing cards, respectively, to read first and second operating temperatures, respectively, measured at first and second temperature sensors, respectively; the first and second temperature sensors being coupled with the first and second server processing cards, respectively; receiving the first and second operating temperatures at a central processing unit; comparing the first and second operating temperatures with first and second predetermined maximum operating temperatures, respectively; transmitting a third request to a plurality of server chassis cooling fans to increase the speed of the server chassis cooling fans if the first operating temperature is greater than or equal to the first predetermined maximum operating temperature or the second operating temperature is greater than or equal to the second predetermined maximum operating temperature; and wherein the first and second server processing cards and the plurality of server chassis cooling fans are disposed at least partially within a server chassis.
