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

Noctua seal of quality

I am using the Noctua NH-U12S Redux on a Ryzen 5 5600 overclocked to 4.65ghz. Running Cinebench R23 at full load I was topping off at 81-82c before adding this second fan and now under full load running the same test, I max out at 76-77c. Thats a 5-degree drop for only $18.18 with tax.

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 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.

rubber pads not for this model

Using a second fan for a push/pull configuration. Not sure if it makes much difference, but worth a try

Did bring down my temps from the usual 70c on load in my hp omen case to 53c on my meshify c case that had 3 intake and 3 exhaust fans. Had in a push/pull config on the cpu..

it comes with everything including fan clips. man. thanks noctua. This is how they all should come though.

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

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.
