> 3 dayDer Noctua ersetzt bei mir einen in die Jahre gekommenen Scythe Mugen 2, welcher auch schon ein ganz ordentlicher Kühler ist.

> 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.

12-06-2025Wanted to cool my Ryzen 3900x and the Wraith cooler that AMD provides is a noisy beast with 2 heatpipes and cant even keep the temperatures down without waking up the neighbors. Pushed the boat out and opted for the Noctua being one of the most expensive air coolers in the market, but boy is it worth it. Running FAH on 20 cores it hums a bit, but nowhere near the Wraith, and on idle i really have to check whether the fans are on or off.
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.
