Greater than one weekHace mas ruido que el cooler Master de mi otro ordenador. Y este me ha costado el triple. Pensé que era mejor por consejo de un amigo.

Greater than one weekExcellent product but I had some troubles while installing the new cooler. The grey spacers that were provided for my AM4 socket didnt fit my system because the heatsink wouldnt reach the mounting bracket no matter how much pressure I applied. So I used the white [AM2(+)/AM3(+)/FM1/FM2] spacers which are slightly taller than the grey ones and the heatsink screwed in properly. I was able to tighten the screws all the way in and the heatsink doesnt move at all.

03-06-2025I really think this is the best cooling system for 95% of pc builders. The cooling performance is pretty identical or better than AIOs without having to worry about pump failures or leaks, it is quieter than AIOs, and its small enough to work with most cases, motherboards, and ram. I even have it in my mini itx h200. Unless youre using a case without the CPU clearance, need something cheaper, or want extreme cooling like phase changing or maybe a custom loop; it really seems like the best choice.

> 3 dayThis cooler, albeit a bit on the expensive side for some, is definitely one of the best out there. Lowered my temps on my 5800x by a whole -10c coming from a Hyper 212 Black. It tames that hot CPU very well. Also gives the CPU a tougher time to ramp up to a higher heat, (fights the heat climb better) Would highly recommend.

> 3 dayÈ il terzo dissipatore che acquisto ed utilizzo…ma conquista il primo posto a ragione di una ottima qualità costruttiva, silenziosità, facilità di montaggio e capacità di dissipazione. Il prezzo può sembrare altimo, ma vale ciò che costa. Il look è più sobrio rispetto a quelli di altre marche, comunque di grande effetto. Non interferisce affatto con le RAM, ne con altri componenti

> 3 dayFits my NR200 itx case perfectly. Keeps a 3700x cpu below 70c while cpu mining, all while amazingly quiet. Noctua really is the best!!

> 3 dayIve always wanted the cooling power of a top-of-the-line Noctua cooler but didnt want half of my build obscured by the massive heatsinks and fans. The NH-U12A fits the bill perfectly! Installation was a snap and the fans are very quiet while keeping my CPU at low temps. Most importantly, my RGB memory sticks are still visible!
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.
