Noctua's latest coolers feature their classic U-series single tower CPU coolers which have received more than 400 awards and recommendations from the international press. The S-version's 45mm slim shape guarantees 100% compatibility with tall RAM modules and at the same time, its fine-tuned design and the class-leading fans with PWM support provide fully automatic speed control allowing it to further improve its predecessor's renowned quiet cooling performance. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system, Noctua's proven NT-H1 thermal compound and a six years manufacturer's warranty, these slim tower coolers are a complete premium quality solution that combines outstanding performance, quiet operation and excellent compatibility.

Q: Hi, I have just purchased this cooler. Does it come with a mounting bracket? Currently on the official Noctua website it says: NH-U12S (AM4 mounting included since 2019, only older coolers require upgrade kit) So do you ship the mounting kit as well for AM4 boards?
Answer by Website User on 2nd August 2019
Yes, this should come with it as our stock is not that old.

Q: Noctua now say that these are now compatible with AM4 boards - only the 2018 and before need the special kit. Can you confirm this and, if true, that you do not have 'old stock' which will require the add-on kits?
Answer by Website User on 1st April 2019
I can confirm out stock will not have the AM4 bracket so it will need to be requested from the manufacture after you receive your product.

Cool and quiet

Paul Goodway

January 2022

I've had people tell me that this is the best aircooler around and they're not wrong. There are parts in the box for many different sockets and it's really incredibly easy to install. The instructions are super clear to understand even for someone like me who has only ever built one PC before. Everything just clicked and screwed together the way that it should. I was a little bit worried about how much thermal paste to use, but the amounts suggested by the instructions worked perfectly for my CPU. The fan comes with a low noise adaptor that will limit the rpm and make it even quieter - but honestly at the moment it's not needed. It's so quiet under normal operations that I don't notice it at all. The thermals on my new PC are brilliant and even under heavy load it doesn't get very hot at all. A friend is going to build a PC soon and I've told him to get a NH-U12 for his rig - honestly can't praise it enough.


May 2021

Obviously a major upgrade from the stock cooler. The fans are very quiet at idle as expected for this brand. The second fan to use this as a push-pull configuration is a good upgrade, a package including this would be nice.

I haven't installed a CPU cooler in a number of years but this was very easy to do. Great build quality and instructions were clear to understand.


February 2021

Great price and the fan is perfect for my new PC build; I can barely hear the fan going even when gaming, massive improvement on my previous CPU fan that sounded like a jet engine!

Marian T.

January 2021

Solid, well made, amd and intel adaptor kits, thermal paste and clear instructions included. Honestly I can't find any faults. My gaming cpu is chilling at 40 50 degrees Celsius so Noctua well done. Top quality!


November 2020

Great product, would have liked it if it was a little cheaper.

Mr Karl Edwards

April 2020

This cooler works very well: it's easy to install, it's very quiet, and the temperatures are very good.


February 2020

Cpu has been running extremely cool (ryzen 5 3600)


October 2018

Just silent and cool as ALWAYS
