> 3 dayJust finished installing the cooler, and Noctua did a great job again. would give 15 stars if I could. Even packaging itself worth more than 5 stars :)

> 3 dayThe keeps my CPU nice and cool and is nice a quiet. my only complaint is how the fans hang on the heat-sink. Not 100% even with the heat-sink. Doesnt impact performance. Purely visual.

> 3 dayJust wanted to begin by saying that I started off on the wrong foot by purchasing a non-liquid cooled Alienware R12. The heating and noise issues those cases have are horrible since the power supply sits right over the cpu and stock cooler. So side note, if youre buying an Alienware because you just think theyre so cool, get an AIO for the CPU. That being said I swapped cases and put the Noctua NH-U12A on it and had about a 40 degree temp drop/improvement on the processor with very little fan noise. Much happier with my temps with a new case and this CPU cooler.

Greater than one weekThis cooler works just as well as the larger models but leaves plenty of space to still see your RGB memory and other affectations on the motherboard. Would gladly recommend to others.

> 3 dayVery well build product, excellent, as described, price range expensive but if last as described then justifiable.

10-06-2025Après beaucoup d’hesitation avec le nh-d15 (qui est beaucoup plus imposant) et la mise n place d’une solution watercooling (plus délicat en cas de panne de la pompe) , je me suis finalement décidé à prendre ce NH-U12A, dont les résultats en test sont très bons (cowcotland, comptoir hardware, etc).
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.
