Noctua NF-A14 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

They work and are silent, moves tons of air and has no issues with thick radiators and grills. They need to make these standard on the Corsair H110!

Noctua has always been my go to fan. Never disapointed

You pay a few extra bucks for Noctua fans, but they move a good amount of air and are very quiet. The six year warranty isnt too shabby either.

Best fans you can buy for your PC without a doubt. Extremely quiet and extremely effective. And extremely ugly.

The only thing that would make me happier, is they offered this in gray or black. Otherwise these are just what my Corsair H110i needed, and my case lets me tuck them out of view if I use a top mount push configuration!

This seems to be a great fan for moving air but not nearly as quiet as advertised or expected.

Excellent fans, very quiet.

These fans are fantastic in every way (ha ha,m get it fantastic ?). Everything from the retail package they come in to the accessories provided for mounting and cable extensions. The plastic quality is top notch and the plastic molding is perfect with no noticeable plastic blemishes or burrs. They blow lots of air even just above stall speed and are anyplace from silent to a nice hum in terms of noise. At the highest speed with full 12 volts, they are very noticeable but the noise they give off is nice and not high pitch or grindy. Just smooth nice white noise. I used 5 of these in my air 540 case to get temps and noise down along with a nzxt fan controller. The brown color is the only negative these have for me. After trying quite a few other brands including NZXT and Corsair and they had terrible fans with failures out of the box. The Noctua fans (5 of them) all worked flawlessly out of the box. The cost might be a little on the high side but given the warranty and build, it is very much worth it.

I dont know where to begin. I redid my case/cooling fan setup with 2 Noctua 140mm and 2 120mm fans. The difference is superb, both sonically and thermally.

too loud
