From the brand
Noctua Cooling Solutions
Noctua's premium cooling components are internationally renowned for their superb quietness, exceptional performance and quality.
Product Description
Continuing the renowned legacy of Noctua’s award-winning NH-U9 series, the NH-U9S is a premium quality quiet CPU cooler in classic 9cm size. Its asymmetrical design with 5 heatpipes not only provides even better cooling performance than the previous generation but also improves compatibility: Thanks to its 95x95mm footprint, the NH-U9S clears the RAM and PCIe slots on all Intel and most AMD based mainboards, including µATX and ITX. Combined with its 125mm height, this makes the NH-U9S a highly versatile solution with excellent case, RAM and PCIe compatibility. The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quietness of operation and a second, optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-U9S is a deluxe choice through and through.

|---|---|---|---|
S version with better compatibilityLike its bigger brothers NH-U12S and NH-U14S, the NH-U9S features a revised, slimmer layout: Whereas the NH-U9B SE2 was 120mm deep with its two stock fans, the NH-U9S is asymmetrically built and measures only 95mm with its single, more efficient NF-A9 fan, thus providing better performance and compatibility at the same time. |
100% RAM compatibilityWith its 95x95mm footprint, the NH-U9S does not overhang the RAM slots on current Intel and most AMD mainboards. This gives the user full access to the memory modules and emsures 100% compatibility with tall heatspreaders or optional memory fans. |
100% compatibility with PCIe cards on mini-ITXMany Intel LGA115x based mini-ITX mainboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-U9S provides full compatibility with PCIe cards, be it on ATX, microATX or ITX. |
NT-H1 thermal compoundHaving received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. |

It comes with thermal paste in a deceivingly big tube, which only lasted for 2 applications since I had trouble with it the first time, and installation guides for either Intel and AMD CPUs.
Make sure you have the right bracket that comes with your motherboard.
I had a lot of issues seating it, and had to do a couple of practice installations before committing to doing it with the thermal paste. The screws had trouble lining up and I ended up wiggling the unit a bit too much for my liking the first try, so I had to clean up the paste and try again. Second time was just as difficult but I managed to get it seated and screwed in place with little movement. Placing the fan back on was also a pain and I ended up digging my finger into the radiator (ouch) but after everything was over with, it was truly worth it. It felt like a sturdy and well crafted little unit, and I liked the brown and tan color of the fan. The extra noise was to be expected, and I don't mind it most of the time.
My temps were brought down to 40c during normal use, and between 50c and 60c on high load such as gaming.
Overall, I'm quite pleased with the quality and how well it's working. I don't think I'll ever go back to all-in-one coolers ever again, and will go the custom route if I ever *wanted* it, since I clearly don't need it.
The installation was probably the part that frustrated me the most, besides the sad amount of thermal paste which is valued at $10 a tube (if it didn't come with the unit) and it's one of the cheaper ones on here.
The same PC shop I went to gets theirs in bulk and sells the little true-to-amount tubes for only $5 and they last for 3 applications. Support local whenever you can, it benefits you and the shop. I would've ordered through them too if I wasn't short on cash and needed to use my $50 gift card I've been saving since last Christmas.
tl;dr Great quality, painful installation, brought my ambient 95c temps down to 40c.
I installed this cooler in a brand name pre-built small form factor machine. I was hoping that I can use the existing stock cooler backplate to just "plug" the Noctua cooler (15 minute job at best). This did not work as the existing back plate poles were very short and male threaded. I had to remove the motherboard to replace the backplate. However, the back plate of my pre-built unit included the threaded holes X 3 to secure the CPU clamp which the Noctua back plate did not. As a result, I have to add threaded clips / washers to secure the CPU clamp. I am quite sure that this Noctua cooler works well without issues on all popular brand motherboards; just be prepared to maybe spend a bit more time (a couple of hours more) if you run into these issues on pre-built units with proprietary motherboards. I am still giving this cooler five stars as it is not their fault with compatibility but with the proprietary nature of this motherboard, which can happen to any other brand of CPU cooler.

Overall this is a great alternative to the NH-U12S, being a smaller cpu cooler that is staggered to allow for 100% RAM clearance. Noctua continues to be the best option for CPU air cooling.
