Award-winning NH-U12S cooler

Tens of thousands of enthusiast users all over the world swear by the NH-U12S’s quality and performance. Recommended by more than 200 international hardware websites and magazines, it is renowned as being one of the best 120mm coolers on the market. design

The NH-U12S is black from head to toe: Featuring a black coated heatsink, black fans with black anti-vibration-pads, black fan clips and black mounting parts, it’s right at home in all-black builds and easy to integrate with other colour schemes.


Using the optional NA-HC1 and NA-HC2 heatsink covers as well as the NA-SAVP1 anti-vibration pads (available in black, blue, green, red, yellow, white), the NH-U12S can be fully customised to fit popular build colour schemes such as black and red or black and white.

100% RAM compatibility

Thanks to its slim design with only 45mm fin depth, the NH-U12S will not overhang the RAM slots even with two fans installed. This gives the user full access to the memory modules on all current CPU sockets and guarantees 100% compatibility with tall heatspreaders or optional memory fans.*

Classic 120mm tower size for excellent overall compatibility

Standing 158mm tall, the NH-U12S is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm wide (including fan and fan clips), the cooler stays clear of the top PCIe slot on most standard ATX or Micro-ATX motherboards, ensuring optimum compatibility with multi-GPU setups.

NF-F12 120mm Focused Flow™ fan

Recommended by more than 150 hardware publications and thousands of enthusiasts world-wide, the Noctua's premium quality NF-F12 Focused Flow™ 120mm fan is renowned to combine superb static pressure, excellent heatsink performance and surprising quietness of operation.

PWM support and Low-Noise Adaptor

The NF-F12 120mm fan supplied with the NH-U12S supports PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation.

Anti-vibration pads and fan-clips for second NF-F12 (optional)

For users who want to achieve even better performance by adding a second, optional NF-F12 PWM fan to create a push/pull setup, the NH-U12S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.

SecuFirm2™ multi-socket mounting system

Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) and LGA20xx (LGA2066, LGA2011-0, LGA2011-3), as well as AMD AM4, AM3(+), AM2(+), FM2(+) and FM1, the SecuFirm2™ mounting included with the NH-U12S is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.

Compatibility with past and future sockets

Thanks to Noctua’s SecuFirm™ ecosystem, the NH-U12S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets, which makes the NH-U12S a safe long-term investment.

NT-H1 thermal compound

Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds.

Soldered interface between heatpipes and fins

With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-U12S’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.

6-year manufacturer’s warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-F12 features an MTTF rating of more than 150.000 hours and the entire NH-U12S package comes with a full 6-year manufacturer's warranty.

* Some AMD mainboards violate the 96x114mm keep-out zone specified by AMD, so the NH-U12S can only be used with RAM modules of up to 40mm height on these boards. Please consult our compatibility list for details.

Really Good Cooler

Would recommend - yes

Great cooler! I would've liked to get the D15 as I intend to upgrade the CPU down the track, but it would've been pushing it to fit in my case so I played it safe and went for the U12s. Absolutely no regrets here! I upgraded from the stock AMD Stealth cooler (from the 3600 CPU) which I'd used for just a couple of weeks. While I didn't mind the stealthy look of the stock cooler, I was put off a bit by the noise and I wanted to do some mild overclocking of the 3600 which I wasn't sure the stock cooler would handle well. After installing the Noctua, the temps dropped about 10°C under normal usage, as well as just being massively improved on the noise side. It comes loaded with stuff in the box including their good thermal paste and a bunch of mounting hardware - and installation was a breeze. I love the sleek black look of it - I would've never bought the cream+brown standard Noctua colours, no matter how good the cooler is - so I'm glad they did this Chromax line of coolers because now you can have the performance on top of great looks. The one tiny thing I found was the fan mounting clips just never quite sat right - even after install I'm unsure if I clipped them in correctly - but it is apparently working fine so I will leave it until I next take the system apart. Highly recommended - this is my first Noctua purchase and I can see myself coming back for other gear of theirs.
