NH-U12A SPECIFICATIONS VIDEOS Reviews Service ACCESSORIES Buy The NH-U12A is the latest, 5th generation of Noctua’s award-winning NH-U12 series of 120mm size premium-quality quiet CPU coolers. Conceived to push the envelope of the 120mm form factor, it combines two of Noctua’s flagship model NF-A12x25 PWM 120mm fans with a completely redesigned heatsink featuring 7 heatpipes and an increased fin surface area for superior heat dissipation. This way, the NH-U12A can rival the performance of many 140mm size coolers while offering 120mm class case and PCIe compatibility. Topped off with the trusted, pro-grade SecuFirm2™ multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U12A is a deluxe choice that combines top-tier performance with excellent compatibility and outstanding quietness of operation. / Details 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 LGA1851/LGA1700 and AM4/AM5Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA1851/LGA1700/LGA1200/LGA115x and AMD AM4/AM5 based motherboards, which ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders. 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 LGA1851, LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) as well as AMD AM4 and AM5 (since 2019), 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. Offset mounting option for AMD AM5The NH-U12A includes Noctua’s offset mounting bars for AM5 that make it possible to install the cooler shifted towards the south side of the socket by 7mm, thereby achieving better contact quality right above the CCD(s). This improved contact exactly at the processor’s hotspot can significantly reduce CPU temperatures with typical improvements in the range of 1-3°C. 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-H1 thermal compoundNoctua’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 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. * In cases with more than 158mm CPU cooler clearance, the rear fan can be moved upwards to make room for memory modules taller than 42mm.

Our case compatibility list helps you to quickly identify which PC cases offer sufficient clearance for which Noctua CPU coolers. The compatibility indication is based on the height of the coolers (including fans) as well as the maximum CPU cooler height specification given by the chassis manufacturer. Caution: Please note that the fans of some tower coolers (especially larger models with 140mm fans, e.g. NH-D15 or NH-U14S TR4-SP3) may overhang the RAM slots and that this can cause compatibility issues if RAM modules taller than 32mm are used. While the fans can be moved upwards to increase RAM clearance, this will increase the total height of the cooler and thus requires additional clearance inside the chassis. As a rule of thumb, if the fan overhangs the RAM, the maximum CPU cooler height specification of the case must be at least the size of the fan plus the height of the RAM minus 7mm (accounting for the height of the socket and CPU). For example, if a cooler uses a 140mm fan that overhangs the RAM and 46mm tall RAM modules are used, the max. CPU cooler height specification should be at least 179mm (140+46-7=179). For further information and instructions on how to move up the fan for each cooler model, please click the height specification link. Disclaimer: We create and update our compatibility lists with utmost care. However, case manufacturers sometimes change parts or details of their products without prior notice or explicitly indicating a revision. Therefore, Noctua cannot accept any liability, nor in any other way be held responsible, for the following compatibility information.

Can't find the case you're looking for? Please don't hesitate to contact our support team at support@noctua.at in order to obtain compatibility information for cases that aren't listed above.

When modern CPUs use their turbo modes, they can (depending on the configuration of the UEFI BIOS) dissipate much more heat than indicated by the manufacturer’s TDP (Thermal Design Power) specification. Just like manual overclocking, this puts higher demands on the cooling solution. Our CPU compatibility list helps you to choose the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned. We classify our coolers according to the following categories: best turbo/overclocking headroom medium turbo/overclocking headroom low turbo/overclocking headroom compatible without turbo/overclocking headroom compatible with certain restrictions (see comment) incompatible (see comment)

For further information on CPUs exceeding their TDP ratings and how to configure the UEFI BIOS in order to avoid excessively high temperatures, please see this FAQ.

Please also see our general buying guide, motherboard compatibility list and FAQs for further help on how to select the best cooler for your configuration.
