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.
