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 9):
The method of  claim 1 , further comprising:\n in response to determining that the first fan is not a fan of the first fan type:\n comparing, by a second comparison, the frequency of the tachometer signal output by the first fan while the PWM control signal has the first PWM duty cycle to an expected tachometer frequency for fans of a second fan type when receiving a PWM control signal of the first PWM duty cycle; and \n in response to determining, based on the second comparison, that the first fan is a fan of the second fan type, providing an indication that the first fan is a fan of the second fan type to the fan controller.
