Noctua NF-A14 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (140mm, Black)

I didnt care much for retail versions due to their color. I went bought some of these fans and used a fan controller to lower the RPM to near silent operation. Same quality as the retail but with more airflow and better color.

Used Noctua fans for `bout six years, these have better cfms and static pressure than my originals. Bought to replace the stock Corsair H115i radiator fans after investigating them.

Wanted to upgrade my Noctua NF-F12 x 3 to a pair of these, but going from 22 db to 31 db is noticeably loud. Luckily these are PWM, so I can at least tune the speeds when its not that hot otherwise Id have to axe these. At full speed, a pair of these cool a few degrees better than 3 of Noctua NF-F12. But I dont know if thats due to moving the Noctua NF-F12 to exhaust ports. But well find out next summer.

They performe well and are only loud at max load which it never runs because the temperatures are not that high.

No LEDs but the best fans I have used so far in my 25 years with building systems. I would recommend these to anyone who wants quality verses pretty lights.

High performance fans, fantastic quality as expected from Noctua backed by a 6 year warranty. I think I have found my new favorite fans.

Works wonder - a little noisy but well worth it for the performance! Will pick up a few again down the line!

Works as an intended great exhaust fan for my computer. Its a tad noisy at over 1500 RPM--which rarely occurs-- but it gives me peace of mind knowing my overclocked computer is getting the exhaust it needs.

Works great

These fans really SUCK! the air directly outta my case! I will nvr use any other fans in my builds ;)
