US 12,641,757 B2 · Controlling electric fans in cabinet assemblies

Abstract

An example method for providing cooling capacity and reducing power consumption of a server assembly is disclosed. The method includes receiving temperature information corresponding to a CPU of an electrical component in the server assembly, which further includes an equipment room, and a cabinet fan module positioned adjacent to a side of the equipment room. The cabinet fan module includes electric fans therein, and the electrical component is implemented in the equipment room. The method includes determining a current power level of the CPU, and determining, using the temperature information and the current power level, a first operating speed for the electric fans. Furthermore, the method includes combining the first operating speed with a second operating speed received from a proportional-integral-derivative controller to determine a combined operating speed. The method still further includes instructing the electric fans to operate at the combined operating speed.
