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

Used to add 2nd fan to an NH-D15 where the included 2nd 140mm wouldnt fit due to case width issues. This 120mm fit fine. Using the supplied 2 fan splitter I now have about a 4-5c lowering in temps across idle all the way to full throttle.

It’s like the first fan, the silicone brackets for the sides of the fan are a bit larger, so the clips have a harder time of going on but once you get it on its good. It comes with a Y-plot 4 pin connector and 2 extension cables for it as well. Great buy, worth it. Dropped temps well.

Great add-on. Temp dropped by about 8C under load.

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

Dropped my temperatures a further 4 degrees Celsius compared to my single fan unit. Highly recommend

This fan drops my Temps about 3 C with the Redux cooler but the package was damaged luckily the fan and accessories had taken no damage.

This is a great fan that runs silent and keeps my PC cool. I actually ordered it to replace another brands fan on my heatsink and was able to rig it to fit on that heatsink. Im very satisfied with this fan.

Mounts the same way as the CPU fan that comes with the cooler. One thing to note for those that are concerned with aesthetics, the rubber pads on this fan are slightly thicker than the ones one the ones that come with the cooler. Theres a slightly larger gap, but either thats intentional or I just happened to get some slightly thicker rubber pads. Otherwise, doesnt bother me too much.
