Abstract: Cooling devices, such as fans, installed in a computing device can be automatically identified by reading an encoded signal from the cooling device's tachometer signal line. A cooling device can temporarily output an encoded signal in response to a trigger event, such as a power on event (e.g., powering-on of the cooling device). A controller, such as a baseboard management controller (BMC), can receive the encoded signal and decode the signal to determine identification information about the cooling device, such as vendor information and/or model information. The identification information about the cooling device can be stored, logged, output, and/or used to customize the operation of the cooling device.
