NH-U12S Slim design for 100% RAM Compatibility CPU Cooler

The NH-U12S is the latest 12cm model of Noctua’s 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 NF-F12 Focused Flow™ fan with PWM support for fully automatic speed control allow 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 full 6 years manufacturer’s warranty, the NH-U12S is a complete premium quality solution that combines outstanding performance, quiet operation and excellent compatibility.

Award-winning NH-U12 series

The NH-U12S is the latest version of Noctua's award-winning NH-U12 coolers. First introduced in 2005, the NH-U series has become a standard choice for premium quality quiet CPU coolers and won more than 400 awards and recommendations from leading international hardware websites and magazines.

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 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™ mounting system

Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1700 (since 2022), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) and LGA20xx (LGA2066, LGA2011-0, LGA2011-3), as well as AMD AM4 and AM5 (since 2019), 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

Complying with the open SecuFirm™ standard, the NH-U12S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets.

NT-H1 thermal compound

Having 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.

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.
