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

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

This cooler in combination with the 2nd fan upgrade kit dropped my CPU temps from almost 80 degrees to 55 at most under high stress. They have been absolutely amazing and rarely even need to go above half of their potential RPM making my system as a whole way quieter than it was before. Not to mention the price for what youre getting if you do take the bundle, definitely worth the price, no more stutters no more hot CPU wonderful product

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

Solid upgrade for the single fan. Second time ordering the product but glad this one came in.

Perfecto para el procesador 5600x y 5800x. La marca ofrece mucha información para seleccionar de forma correcta el sistema de refrigeración adeacudo para el eso que se le va a dar al procesador.

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!

Great product. Thats pretty much it.

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.

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.

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