Abstract
An information handling system includes a hardware processor and an embedded controller (EC), an installed cooling fan with an identification hardware gasket of a plurality of hardware gaskets where the embedded controller executes computer readable program code of a hardware fan configuration detection system to detect a type of the installed cooling fan within the information handling system via a hardware fan detection circuit. The hardware fan detection circuit includes a resistor network operatively coupled to the EC and a plurality of PCB contact pads operatively coupled along the resistor network, where placement of the identification hardware gasket of the installed cooling fan on a first PCB contact pad of the plurality of PCB contact pads identifies the installed cooling fan by generating a fan contact signal for selection of a fan operation table to operate the installed cooling fan.
