Review on Noctua NF S12A PWM Premium Quiet by Richard Koh

I have a new AirStream trailer and the Dometic fridge has some type of cooling duct with outside access. There's a lower vent door that lets cold air in and a higher vent door that lets hot air out with a fairly noisy fan that kicks on when the cooling fins heat up. On our first outing, the fan noise almost drove my wife and I insane. I added rubber isolation pads to the fan but that only reduced the noise by 40%. After searching some of the AirStream forums, I found that many RV owners are replacing their fans with this fan. I bought two of these, added a noise canceling resistor (included) and now I have better airflow with less current and no noticeable noise at all. See photos before and after. Caution: The connectors on the various wires can easily come loose, especially if you wrap them with tape to protect the wires from the elements. I discovered this the hard way, so I ruled out all the connectors when I plugged these fans in a second time. Oh, for all you campers out there, the yellow wire goes to 12v and the black wire goes to ground. Ignore the blue and green wires.
