09-06-2025This CPU fan is quiet and easily installed in my Dell XPS 8940. NOTE: My PCs width is 6-1/2 and this CPU fan requires about 7 in height to close the left side panel. I have my PC next to a piece of furniture and am not worried about looks so I am keeping this CPU fan versus the OEM CPU fan.

> 3 day-20 degrees cooler than the liquid AIO I had installed previously. Easy to mount. 60 c temps at 100 percent cpu usage in stress testing. i7 8700k overclock 5ghz, never seen it go above 55 c while playing Modern Warfare. Great cooling solution if you can fit it. My setup is:

> 3 dayI bought this to replace the single 140mm radiator that came with my new MSI Aegis 5800x. I was hitting core temps of 90+ degrees at default settings for the PC. Im rarely seeing 65 degrees now. Easy to install on AM4 socket. If you are replacing an existing AM4 cooler then fold some cardboard to set behind the case cutout for the cpu to keep inward pressure on the mount before removing existing bracket. Excellent cooler!!!

> 3 dayWater cooling is so stressful, worrying about the pump giving out, algae, leaking onto your motherboard, refilling..

> 3 dayInstalled this unit on a Ryzen 5700X. Keeps my CPU very cool and only runs at 30% capacity. Have had no issues at all cooling my chip even at the highest gaming levels. Very quiet, case fans (also Noctua) are louder than this cooler is.

> 3 dayGreat cooler, fan, etc. However, the package from Noctua, it bends the bottom fins on the edge. I confirm this by having Amazon replaced the original unit. Pls fix the packaging, Noctua.
The NH-U12A is the latest, 5th generation of Noctua’s 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 and Noctua’s proven NT-H1 thermal compound, the NH-U12A is a deluxe choice that combines top-tier performance with excellent compatibility and outstanding quietness of operation.

Classic 120mm tower size for excellent overall 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. |
100% RAM compatibility on LGA1700/1200 and AM4/AM5Due 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.* |
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. |
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. |

140mm performance in 120mm size
Thanks to its completely revised 7 heatpipe layout, 37% more fin surface area and a dual fan push/pull configuration that uses the new, state-of-the-art NF-A12x25 fans, the NH-U12A can actually match or even outperform many 140mm sized coolers.
