Noctua NF-S12A FLX, Premium Quiet Fan, 3-Pin (120mm, Brown)

If you are looking for a quiet computer fan, this is it. I now hear the other fans that I never heard before.

Aside from the anatomical medical color, lack of LED bling, these Austrian designed and Taiwan built fans are wonderfully designed and very quiet. The S12A FLX model ships with two cable variants that step down the power to reduce the RPMs (and noise) from a stock 1200 to 900 and 700. I use mine with power throttles and even at their full 1200 speed they are quiet when compared to my previous brushless fans. The dark brown rubber anti-vibration pads are soft and removable. Instead of screws, these fans come with stubby metal screws and soft silicon anti-vibration pegs that can serve to mount these to the outer case. I have used pairs of these to replace the push-pull stock fans that came with the Corsair Hydro coolers on both of my home computers and am very happy with the reduced noise levels. These fans come with a six year warranty

ok

Really nice case fan. I used three of these in an HTPC and I literally cannot hear ANY fan noise coming from the unit. They are pricey, thats for sure, but I do not regret my purchase. I will definitely buy from Noctua again in the future.

This fan is very quiet. I used it in my media center which I want to stay cool and quiet.

Silent. Silent. Silent. Got to have silence when it comes to case fans. Replaced my exhaust fan with one of these and its great. Hate the color scheme but oh well. Bought this before I knew about gentle typhoons, Both work just as good. Giving 3 stars just because its ugly as hell.

These are quiet and move quite a bit of air. Well worth the price paid thus far.

These fans suck. Or blow. Either way, they do well moving air. Not too noisy about it either. I use the system board bios to control the speed. At 100%, they do make some noise, but all fans do. These seem to move more air per decibel (unofficial) than the Corsair fans I also have at the same size. Not sure if the RPM is apples to apples, but set at xxx%, this moves more air, and is quieter by comparison.

Dont plan on buying if your planning on doing any overclocking, otherwise, Noctua fans are about the best you can get for silence/airflow.

Works great, low noise.
