Noctua NF-P14s redux-1200 PWM, Quiet Fan, 4-Pin, 1200 RPM (140mm, Grey)

Specifically using NZXT cases with Kraken AIOs. Stock top of case fan is 120mm and not the quietest. Replaced top of case fans with this 140mm unit. Asus fan speed control helps quiet everything down and the Noctua does its part with its efficient airflow at lower speeds. No rattle or vibration EVER. Would definitely buy again and this grey colored series is much less the eyesore that the old orangy-beige fans were.

Fine quality fan that runs extremely quietly and still manages to move a modest amount of air. The usual excellent Noctua build quality, backed by an excellent customer service/warranty.

I installed 2 fans on the top panels of my case. Quite or barely silent. Working good.

Theyre built like what you would aspect of noctua.

Got two for back of the media cabinet. They are connected to the media center with wires existing the media center case ... so essentially they are moving air for all the electronics inside the cabinet. Set them to run at 100% all the time, very nice so far. Good airflow and very very quiet.

Just as expected, the fan moves a nice flow of air, quietly. It feels strong and durable, state of art packaging and good locking product

Really quiet fans !

Work very well for getting some good airflow fairly quietly when looks arent the top priority. Unlike some other Noctua fans it comes installed with a longer heavily sleeved pwm wire, not a short wire with a included extension.

Noctua Redux fans are the best fans you will find in their price range, and mostly any other price range for computer related fans. The color they come it, which is nice (two tones grey), is nice, but it would be nice to have them also in in all black and all white too. However, if you are looking for quality, air flow, and low noise, plus a 6 year warranty, get these. Other fans are no where near the build quality of these fans.

I purchased 2 of these fans. Their housings are thick enough where my son could not fit the fan anywhere except the front of his case with a B550 Mortar board. After a few months, 1 fan died. I contacted Noctua support and waiting resolution.
