Noctua NF-F12 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (120mm, Black)

Ordered two of these fans, both of which made quiet but annoying bearing grinding noises even at low RPM. The NF-F12 (non iPPC) I have makes no such noise.

These fans run well and quietly. Im not a fan of the brown corners, wish they were black or came in options. Im not going to pay extra just for replacements in whatever color.

Load temp went down about 6C at about 250 RPM lower than the noisy stock fans that came with the Corisair H105, and I noticed almost no increase in sound between idle and load. Cant recommend this fan enough for radiators.

The fans work well, but they are a bit too loud for my taste. I prefer the noise level of the stock F12

I have used these since their release on all my builds to replace Corsairs loud and on their AIO coolers. These cool better, are much quieter and their reliability is outstanding. If run at 100% they can be heard but even on Intel 8 core overclocked builds they never need to ramp over 50%. Fantastic fan for high static pressure with low noise. The quality is worth the cost.

The brown rubber in the sides still makes this an ugly fan and honestly its pretty dang loud. It doesnt go down to a very low rpm so its fairly loud compared to my Fractal Design Venturi HP Fans. Those are still my favorite.

I bought this to replace the obnoxiously loud fan on my Lepa AIO cooler. The Noctua isnt silent, nor does it claim to be, but it is much quieter than the fan it replaced. The stock fan on the Lepa was like a shrieking harpy in comparison.

You cant beat Noctua fans. I was skeptical, but they move more air with less noise than any other fan Ive ever used.

Bought these fans to replace the stock corsair fans on an h80I AIO. Temps dropped 8 degrees C full load and they are marginally more quiet.

Great fans and very quiet, they move a lot of air with no issues. I have them mounted on my corsair h100i and they keep my cpu very cool with very little noise. I would highly recommend these for anyone!
