Abstract:
Systems and methods for fan typing and anomaly detection may provide a pulse width modulation (PWM) control signal with a predetermined threshold duty cycle to a fan, receive a tachometer signal from the fan while the PWM control signal has the threshold duty cycle, and compare the frequency of the tachometer signal (expressed in revolutions per minute) to an expected tachometer frequency for fans of a first fan type with the PWM control signal having the threshold duty cycle, according to an RPM vs. PWM curve specified for fans of the first fan type. The systems and methods may determine, based on the comparison, that the fan is of the first fan type and provide an indication that the fan is of the first fan type to a fan controller. Deviations from expected tachometer responses may indicate an anomaly, such as an actual fan failure or a predicted fan failure.

Claim (Index 5):
The information handling system of  claim 1 , wherein:\n the information handling system further comprises a plurality of fan slots, each fan slot being configured for installation of a respective fan into the fan slot; the given fan is installed in a first one of the plurality of fan slots; and wherein when executed by the at least one processor, the program instructions further cause the information handling system to:\n compare the frequency of the tachometer signal output by the given fan while the PWM control signal has the first PWM duty cycle to a minimum tachometer frequency for fans of multiple fan types; and \n responsive to determining that the frequency of the tachometer signal output by the given fan while the PWM control signal is less than the minimum tachometer frequency for fans of multiple fan types, provide an indication of a potential failure or performance degradation of the given fan to the fan controller.
