@Classified just a heads up, this is a 1.45A fan and Duet supports no more than 0.8A on the 12V rail. So you must use an external 12V power supply (or buck converter) on this.
As this is a 4 wire fan, you could connect just PWM control to the Duet board while running VIN and GND to a buck converter that is fed by your main PSU. Connecting the fan monitoring wire reporting RPM is optional..
