> 3 dayThis cpu cooler is top notch. Super easy install, and so far is working fantastically. Z390 board, with 9600K running at 5.0ghz, (4.7Ghz uncore). Aida64 stress test sits right at 70C. Prime95 blend (AVX disabled) doesnt go above 73C. Basically silent when surfing the web or not stressing the CPU. Replaced a nearly 6 year old Corsair h100i which was a good cooler, but so far this one is definitely slightly better than the H100i was. No software to worry about (no water to worry about), just plug it in and go. Would buy again. Noctua is great - I RMAd a 5 year old fan recently and they were awesome to deal with. I was tempted to get the NH-D15 at first but it was too tall for my case (Corsair 330R)

> 3 daymolto buono ma caro. è silenzioso senza dubbio anche se non assoluto: lo tengo al minimo (40%) e cmq un po si sente. suppongo che sia una cosa inevitabile tuttavia: qualsiasi parte in moviemento genera un po di rumore

> 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.

> 3 dayWanted to replace the stock wraith prism cooler that sounded like a jet engine when doing anything. The build quality of the product is amazing and has also great at keeping the temps down.

> 3 daysuper easy to mount, even for a motherboard already in the case. My temps dropped 20C from stock for my 3700x
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.
