Greater than one weekWorks great in my nr200. 5900x is locked at 4.5ghz @ 1.196v and runs without issues at 67c under full load on the gigabyte b550 pro ax itx! Comes with a y spliter if your motherboard only has 1 CPU fan header.

> 3 dayI was running a 360 aio, and it was loud, but cool. It stopped working so I gave this a shot. Guess what? Idle on water, was 45c. On this? lol 25-26. On load used to be 85c. Now? 55 on prime freaking 95 for 3 hours. Amazing. 6700k but soon I’m getting 9900k and ordered the d15 for that build. Crazy good, follow instructions and you’re good.

> 3 dayFirst let me say that the NH-U12A is a good cooler, and Noctua really deliver into what they said. Its a cooler that can deliver top performance, very close to the NH-D15, in a smaller factor.

> 3 dayFirst off, I can’t get over how massive it is, to where I wonder about the structural integrity of the motherboard. It actually has a warning that basically says be careful about transferring your pc with the air cooler attached bc there’s no telling what could happen. I imagine if someone were moving their office, they’d have to disassemble the air cooler first to be safe. And somehow the NH-15 is supposed to be bigger. Luckily, I have plenty of clearance with the Asus Tuf Z690 and Be Quiet 500dx case with the nh-u12a.

> 3 dayThe fins are supposed to be soldered to help with heat transfer correct? Well, the dude/gal assembling them, bent the last three and f-ed up on the correct positioning, theres an uneven spacing between the last solder points, and the fins are bent because of this, no clue how it got past quality control as well but here we are
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. |

* In cases with more than 158mm CPU cooler clearance, the rear fan can be moved upwards to make room for memory modules taller than 42mm.
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.
