Noctua NF-F12 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (120mm, Black)

So far so good.

Noctua fans are the absolute best PC Case fans available. Quiet and powerful!

These are great fans and almost worth the money: cool and quiet, quality that you would expect from Noctua.

Nothing can beat Noctua. I needed some fans that pushed air better in the Mini ITX build I was working on. They looked great in my NZXT 200i case. Their rpms and build quality are nothing less than the best on the market. The performance gained from these fans outweighed the pros of owning the corsair LL fans. If you swear by rgb get Phanteks rgb fan covers or use some light strips. Your expensive equipment deserves to be babied! Keep those temps low with these fans! :)

This fan, along with all Noctua fans, is a great performer at lower (sub 50%) RPM. Anything above that, the fan is obnoxiously loud. They sound like a jet engine inside a hangar at anything over that rate. The airflow is great as an unfiltered exhaust or a static pressure fan on a radiator. I personally wouldnt use these as intakes because they require too high an RPM to consistently pull air into the case.

Does the job well, very quite

Nothing negative about these fans. They come packaged nicely great performance and most importantly very quiet. No difference in noise level compared to their normal counterparts. I like the black color would recommend for anyone looking for quiet fans and that looks great.

Bought two fans, one to replace the stock rear fan (120mm) and the second to use as top exhaust inside Fractal Design 7 compact case.

Arguably the best pc case fans ever.

Worked well in my Xbox One, quieted down the noisy stock fan and still kept everything cool.
