> 3 dayI have this on my Ryzen 5 5600X overclocking at 4.5mHz and my CPU doesnt get over 50C while doing stress tests. For the size of the heatsink and fan Im very impressed with how well it performs.

> 3 dayIf youve wanted a Noctua CPU fan for as long as I have, just buy the damn thing. Just make sure you have a case big enough to use it and show it off. Way cooler and more unique than water cooling, in my opinion.

07-06-2025Die Kühlleistung ist sehr gut. Kühlt meinen 3900X selbst unter Last auf unter 50 Grad Celsius bei nur 40 Prozent Umdrehungen. Dabei ist er quasi lautlos. Gut sind auch die Abmessungen. Im Gegensatz zum NH-D15 ist er fast ein Zwerg und das Gehäuse wird nicht zugebaut. Die 4 RAM Slots bleiben voll erreichbar.

> 3 dayI cant believe that this baby could perform better than AIOs. After spending so much money on water cooling system for some years there is finally an alternative that matches and exceeds AIO systems without risk of failure. It can be installed on mini itx motherboards with ram clearance.

> 3 dayQuesto Noctua è facilissimo da montare, chiave e pasta termica sono incluse, riesce a mantenere il mio ryzen 3700x sotto i 60° mentre è sotto carico. Ottimo prodotto, consigliatissimo

06-06-2025Fits my NR200 itx case perfectly. Keeps a 3700x cpu below 70c while cpu mining, all while amazingly quiet. Noctua really is the best!!

10-06-2025Nach CPU-Upgrade auf einen Intel i7700k (von einen Pentium G4560) bin ich erst mal mit meinem bewährten Alpenföhn Ben Nevis geblieben; bis ich dann irgendwann gemerkt habe, dass die Kombination nicht wirklich sinnvoll ist. Ein paar YouTube-Testvideos später hab ich mich dann für den Noctua NH-U12A entschieden, zum Einsatz in einem Corsair-Gehäuse.
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.
