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

    High quality cooler, nicely packaged and performance is excellent. It keeps my 5900x running at 67C under full load (PBO off). I used the included fans at first but found them ugly and kinda noisy. So switched to a single Arctic P12 which actually gave almost identical results but with a lower noise output.

    Im here to answer the age old question, will this cooler work for a Rosewill 4u server chassis? The answer is yes (in my case, pun intended). Im blown away that you can fit this much cooling in a 4U chassis. A 5950x is easily tamed by this cooler. Keep in mind theres probably a mm of space between the cooler and lid however, fits my needs perfectly.

    Acheter pour un i9, le Noctua NH-U12A fait son taf !

    I bought this to cool a 5800x on an Asus Prime x570 Pro in an NZXT H510i case. Although it may not look like it, the standoffs for the mounting kit do allow ample clearance for the capacitors around the CPU socket. The vertical clearance is also fine; theres about 1/3 to 1/2 inch between the side of the case and the cooler.

    I couldnt be happier with this purchase. Mounting took a bit of fiddling, but ultimately this was just a great buy.

    This is a beastly CPU Cooler. Coupled with a Core i7 10700K, my idle temperatures are anywhere between 28 and 33 degrees Celsius. Also, while under heavy load (especially after performing Intel Stress Tests) my CPU does not exceed 64 degrees Celsius. That has a lot to say there. Im glad that I went with an air cooler instead of liquid cooling system. I hope Noctua can follow up with my request and send me replacement brown anti-vibration corner pads; one of the pads on the fan arrived with a rip.

    volevo prendere il dh15 ma siccome è un bestione avevo paura che non ci stava nel mio case, quindi ho optato per questo U12A sempre noctua che dire.. ragazzi si adatta a tutti i tipi di settaggio senza problemi è leggermente più piccolo, quindi più adattivo per venire incontro alle esigenze di noi clienti. Fa il suo lavoro egregiamente! mi raccomando a montare le ventole (MONTATELE PER IL VERSO GIUSTO CON LA FRECCIA RIVOLTA VERSO IL RETRO DEL PC), montaggio semplice ed intuitivo istruzioni in eng ma comprensibili anche per chi non sa la lingua! lo consiglio? SI.

    My last Build was water cooled pump failed once has to replace the cpu and the AIO this decided to try air read all the stuff about this company the cpu has yet to see 70c and full load gaming including VR, probaly wont do water again since on air cooling you can see the fans working cant see the water pump spinning. But Love this cooler and its is stupid quiet even at full speed...

NH-U12A HeaderNH-U12A Header

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 compatibility

Standing 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/AM5

Due 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 fans

The 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 compound

Noctua’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.
