10-06-2025Usato per un 3900x. Le temperature in idle sono calate di quasi 10C rispetto al dissi standard e il rumore ad alti regimi è ridicolmente basso. Perfetto da usare al posto del dh15 per chi ha case mid tower che non consentono luso di dissipatori cosi grandi. Lestetica è soggettiva, ma a me non dispiace affatto. Consigliato

> 3 dayIm using this with an Intel i7 11900k CPU. It works well and runs about 5C cooler than the 240mm AIO I was previously using. At 76F ambient, Im getting individual cores between 40-47C with a mostly idle ubunu desktop. Package is showing 47C-50C. This is with kyronaut extreme thermal paste rather than the noctua included stuff. Benchmark results show a 5% increase with the new cooler overall. (passmark, multiple phoronix tests, geekbench)

Greater than one weekLove the fans on this cooler. They are completely unnoticeable in my system. CPU temperature is also doing better than the stock amd wraith stealth cooler, so I got nothing to complain about. Great product.

> 3 dayProduit reçu conforme, mais il manque les pinces pour fixer le deuxième ventilateur. Relance du fournisseur qui ne répond pas. Je vais voir avec Amazon pour remboursement pour racheter le même mais ailleurs.

> 3 dayDer Einbau des Noctua NH-U12A CPU-Kühlers ist sehr einfach und dauert nur ein paar Minuten. Das Gehäuse des Rechners muss aber breit genug sein. Die meisten kompakten PC-Gehäuse sind 200mm breit oder breiter. Der Einbau CPU-Kühlers in solche Gehäuse ist problemlos. Der Kühler benötigt mindestens 180mm Gehäusebreite.

> 3 dayIve been using this fan for 6 months now, without any issues. This is a excellent high quality fan, I did wish they had it in Red to match my colour scheme, but anyways I rarely look into my PC case anyways so its not a issue for me. I can wholeheartedly recommend this cooler
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.
