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

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.

Works as expected.

I bought this to slap on the front of my NH-D15 so I could move the other two fans back a slot and have three fans, because Im stupid, and was curious to see if there would be much of a difference in temps. Well, there was. About 9c, so Im going to leave it on there.

best quality. Works greats. No issues.

This kit is suppose to be a secondary fan to the NH-U12S Redux Cooler. First, let me say that this is my second Noctua purchase. Their fans and accessories are top notch. They are the ROLEX of the PC Fan industry and dont skimp on quality of their products. The fan upgrade however is not what I expected, the fan blades are entirely different than the one that comes on the Redux cooler. Although, the same size, different blades and the rubber grey sound dampeners are even twice as thick as the fan that comes with the Redux. Not sure if this was a mistake or if Noctua intentionally allowed this variance in product types, but the sound dampener on the upgrade fan makes it very difficult to install and the noise from the second fan is more pronounced which I can tell between the original and upgrade fan.

This fan dropped my NH-U12S coolers capability on my 5800x CPU by 3-4c consistently. To me thats well worth the price. My 5800x turned out to be a good cpu and I am able to boost to 4.7 consistently using the U12S and this added fan. Very happy with it.

EXCELENTE

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.

I had to try this with a new Noctua cooler as the 4 heat pipe with 2 120 mm fans allowed my 5900x to hit 93c under heavy loads, which would cause it to throttle down. This gave me an 8-10c drop, keeping me under 90, I wont do water as I dont like the drawbacks to water cooling.
