> 3 dayBuyers beware if you have a LGA1700 motherboard. Amazon is selling older shipments of this product that do NOT have the LGA1700 mounting adapter plate. Luckily Noctua will send you one for free but it can take up to 20 business days. Very misleading product description.

> 3 dayJust finished installing the cooler, and Noctua did a great job again. would give 15 stars if I could. Even packaging itself worth more than 5 stars :)

> 3 dayA pesar de los problemas con el envío, el producto es increíble. Baja la temperatura unos 5 grados de CPU y GPU, en comparación con mi anterior EVO212, no es gran cosa pero mi equipo a full la GPU no supera ahora los 60 en ningún momento y la CPU con OC sobre 55, y sin achuchar a los fans.

> 3 dayI got this Noctua cpu cooler to replace a single fan AIO. The single fan AIO cooler on an ITX build has the temperatures around 55-60 degrees on idle. After hearing a lot of good things about Noctua coolers, I decided to get this. Installation is easy compared to AIOs. I love that the fans are tooless for maintenance cleaning and installation. I have less cable to deal with because there is no RGB light on this, but my case have enough lights to showcase whats inside. Using the Noctua thermal paste, I was able to lower the temperatures to 38-45 degrees on idle. Thats a good temperature on an ITX build on a hot summer day. When playing video games, the cpu temps shoot up to 70 degrees average, and up to 75 on a really hot day. Im curently using Ryzen 9 3900X, which runs hotter than my previous Ryzen 7 2700X.

Greater than one weekFirst 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.

08-06-2025I replace the stock cooler on my Ryzen 3900x with this cooler and it dropped the temperature about 8-10 c degrees. Also it is very quiet. I am pleased with this product!

> 3 dayI was nervous about installing this because it was my first time installing a large heatsink. Never took the motherboard out and had no problems at all. The fans confused me at first as to how to get them back on but I figured it out. Wayyy better than water cooling

> 3 dayProduit reçu conforme, mais il manque les pinces pour fixer le deuxième ventilateur. Relance du fournisseur qui ne répond pas. Je vais voir avec Amazon pour remboursement pour racheter le même mais ailleurs.
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. |

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.
