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

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.

Kit de excelente calidad, me gustó muchísimo porque es super fácil su instalación. Viene con cables indispensables para alimentar de corriente los ventiladores. Aún así creo que a este kit le faltó para ser el mejor kit; una pasta térmica porque solamente podremos utilizar la que viene de fábrica con el Disipador. Por lo que tuve que comprar una pasta por separado para tenerla en casos como el que actualice mi placa madre y/o realice mantenciones periódicas al computador en general incluyendo el recambio de pasta térmica al procesador. Pero aún así todo es de calidad. Muchas gracias.

The reason why I ordered this kit was for the fan clips I needed an extra set for my fuma 2 and because scythe discontinued their fan mounting clips I thought I would try ordering this redo kit even though I do not need the fan to see if it would allow me to mount the 3rd fan I needed to mount on My

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

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

Great upgrade to an already great cooler. This keeps my Ryzen 9 5900x nice and cool.

The hardest thing to do is keep CPUs and GPUs cool in a confined box. Add to this many GPUs dont activate the fans in a misguided effort to save energy by risking GPU card overheating. Many GPUs prevent or make it difficult to defeat these stupid GPU fan disabling energy saving features. The only answer is to fill the box with fans that keep air cooler by keeping air moving.

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.

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