Award-winning NH-U12 seriesFirst introduced in 2005, Noctua’s NH-U12 series has won more than 600 awards and recommendations from leading international hardware websites and magazines. The NH-U12A is the latest addition to this prestigious series that has established itself as a benchmark for premium-quality quiet 120mm coolers. |
 |
140mm performance in 120mm sizeThanks to its completely revised, thoroughly optimised 7 heatpipe layout, 37% more fin surface area (as compared to the NH-U12S) and a dual fan push/pull configuration that uses the new, state-of-the-art NF-A12x25 fans, the NH-U12A pushes the performance envelope in the 120mm class and can actually match or even outperform many 140mm sized coolers. |
 |
100% RAM compatibility on LGA115x and AM4Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA115x and AMD AM4 based motherboards, which ensures easy access to the modules and 100% compatibility with tall heat-spreaders. On LGA2066, the rear fan will overhang the RAM slots on the left-hand side of the socket, so RAM modules should not exceed 42mm in height.* |
 |
Classic 120mm tower size for excellent case and PCIe compatibilityStanding 158mm tall, the NH-U12A 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. |
 |
Dual NF-A12 120mm fansThe NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. Using this elite-class fan in a push/pull dual fan configuration is one of the cornerstones of the NH-U12A’s commanding performance and acoustic efficiency. |
 |
PWM support and Low-Noise AdaptorsThe NF-A12 120mm fans supplied with the NH-U12A support PWM for convenient automatic speed control through the motherboard: Full performance under load, virtually silent at idle! In addition, maximum fan speed can be reduced from 2000 to 1700rpm using the supplied Low-Noise Adaptors for even quieter operation. |

SecuFirm2™ multi-socket mounting systemNoctua’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-U12A is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use. |
 |
Compatibility with past and future socketsThanks to Noctua’s SecuFirm™ ecosystem, the NH-U12A 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-U12A a safe long-term investment. |
 |
NT-h2 thermal compoundNoctua’s much-acclaimed NT-h2 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 finsWith 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-U12A’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 warrantyNoctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NH-U12A heatsink is built to last, and like all Noctua fans, the supplied NF-A12x25 units feature an MTTF rating of more than 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty. |
