The NH-U12A chromax black is an all-black version of Noctua’s award-winning NH-U12A premium-quality quiet CPU cooler. Thanks to the same proven asymmetrical single-tower heatsink design and state-of-the-art NF-A12x25 PWM fans, it stays true to the NH-U12A’s successful formula of fusing best-in-class cooling performance with superb quietness of operation and outstanding RAM, case and PCIe compatibility. At the same time, the chromax black version with its black fans and black coated heatsink combines these assets with a sleek stealth look. Topped off with the renowned SecuFirm2™ multi-socket mounting system, Noctua’s enthusiast-grade NT-H1 thermal compound, and a full 6-year manufacturer’s warranty, the NH-U12A chromax black is a deluxe choice for customers who seek a highly compatible 120mm heatsink that can rival the performance of 140mm units and looks just as great as it cools.

The NH-U12A has proven in countless tests that it can match or even outperform many 140 mm-sized coolers while offering 120mm class case and PCIe compatibility. This winning combination of top-tier performance and excellent compatibility has earned the NH-U12A awards and recommendations from more than 100 hardware websites and magazines across the world.
The NH-U12A chromax. black is black from head to toe: featuring a black coated heatsink, a black fan 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 color schemes.
Using the optional NA-HC7 and NA-HC8 heatsink covers as well as the NA-SAVP1 anti-vibration pads (available in black, blue, green, red, yellow, and white), the NH-U12A chromax black can be fully customized to fit popular build color schemes such as black and red or black and white.
Thanks to its completely revised, thoroughly optimized 7 Heatpipe layouts, 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.
Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA1700 (LGA17xx family)/LGA1200/LGA115x and AMD AM4/AM5 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.*
Standing 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.
The NF-A12x25 is a highly optimized 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.
The 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.
Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety, and easy installation. Supporting Intel LGA1700 (LGA17xx family), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), and LGA20xx (LGA2066, LGA2011-0, LGA2011-3), as well as AMD AM4 and AM5, 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.
Thanks 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.
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.
With many heatsinks, the fins are press-fitted to the heat pipes. Due to the different thermal expansion coefficients of copper and aluminum, 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 heat pipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.
