Noctua NA-FK1 Redux, Second Fan Upgrade Kit for NH-U12S Redux Cooler

Great product. Thats pretty much it.

best quality. Works greats. No issues.

I bought this fan in addition to the NH-U12S cooler, with the single fan the cooler comes with my temps were around 38-45 at idle and around 60-65c under load. With this fan installed in a push-pull configuration, it dropped to around 35-40 at idle and around 50-60 under load. So for $16, it did help to drop my temps a few degrees, which i think is well worth it.

I was wary because they are suspiciously low priced, but the noctua quality is there. Would recommend.

Was missing the Y-splitter and the low noise adapters. I wasnt planning on using them, but I did pay for them..

Had to modify my original fans clips to work with this fan but it fits tight, runs quiet, and keeps my processor cooler than original cooler master when it was new

The fan is quite silent under 1500rpm and is a really good fan for keeping your processor cool. The brackets only fit on nocrua coolers, so if you have any other cooler youll meed their specific brackets in order for this to work.

Lo conseguí para un cooler alseye, al tener menos longitud el cable hizo más fácil la instalación, además del splitter en Y se le nota de muy buena calidad

This was really easy to install and mounted on to my Noctua D15s fan easily! Helped reduce temperatures of my cpu about 1-3 degrees which was nice. Highly recommend this one!

I bought this fan adding additional to my CPU cooler fans. Now I have 3 fans total on my cooler fans and my temperature (max when gaming dropped from 70 to 60 ) dropped 10 degrees. I would buy again when needed.
