Features

  • 140mm class performance in 120mm size: 7 heatpipes, more surface area and a dual fan configuration with state-of-the-art NF-A12x25 fans allow the NH-U12A to rival many 140mm size coolers!
  • Excellent case, RAM and PCIe compatibility: Fits most tower cases (158mm height), doesn’t overhang the RAM slots on LGA115x and AM4, doesn’t block the PCIe on most ATX and Micro-ATX motherboards.
  • Quiet, state-of-the-art NF-A12x25 120mm fans with Low-Noise Adaptors and PWM for automatic speed control: Full cooling performance under load, virtually silent at idle!
  • Includes high-end NT-H1 thermal paste and SecuFirm2 mounting system for easy installation on Intel LGA1150, LGA1151, LGA1155, LGA1156, LGA2011, LGA2066 and AMD AM4, AM3(+), AM2(+), FM1, FM2(+)
  • Renowned Noctua quality backed up by 6-year manufacturer’s warranty, deluxe choice for Intel Core i9, i7, i5, i3 (e.g. 10900K, 10700K, 10600K, 10980XE) and AMD Ryzen (e.g. 3950X, 3900X, 3700X, 3600X)

Description

The NH-U12A is the latest, 5th generation of Noctua’s award-winning 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. First introduced in 2005, Noctua’s NH-U12 series has won more than 600 awards and recommendations from leading international hardware websites and magazines. The NH-U12A is the latest addition to this prestigious series that has established itself as a benchmark for premium-quality quiet 120mm coolers. Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA115x and AMD AM4 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. * 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. 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. Copper (base and heat-pipes), aluminium (cooling fins), soldered joints & nickel plating * 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. 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.

The NH-U12S was way too close to my memory sticks, but the NH-U12A gave me 1/4 - 3/8 inch more room. Plus, I did drop 3C at idle and 4C at gaming. I am only running 1 fan (120mm Cooler Master Jet Flo) which pushes 95 CFM at 2000 rpms. Works great. I am controlling all 6 of my fans via my BIOS so no need for any speed-controlled cables connected to the fans. If the NH-U12A was just as close to the memory as the NH-U12S, I would have returned it the same day I received it. Overall, I love the NH-U12A cooler. Noctua needs to make a Chromax cover for this cooler. Update - 9 Apr 2019 While running the NH-U12A cooler since 29 Mar 2019. It has been a great addition to my PC. I am running a i7-8086K (4Ghz (5Ghz OC)), EVGA 1080 Ti SC2, EVGA Z370 Classified (gaming). My CPU is running on Auto settings (in BIOS) which allows the CPU multiplier to run the CPU from 4Ghz to 4.6Ghz when the system needs it without OC’ing. This allows me to run only 1 CPU fan. While gaming, my temps max out at 53C and 33C at idle as per MOBO CPU LED readout. If later, I decide to OC to 5Ghz I will install the second fan (DO NOT OC with 1 CPU fan). If you plan to game on your PC, upgrade to the NH-U12A if your PC case does not allow for the NH-D15. I had to return my NH-D15 because my case was just a bit smaller than the cooler.

Enter the Noctua NH-U12A and the online reviews indicated that it was designed to provide better clearance over the taller RAM DIMMs on the market. When I test-fit this cooler onto the I9 mounted on an ASUS ROG Maximus XI Extreme motherboard, it looked like it would indeed mount nicely with some overlap of the RAM DIMM slots. Unfortunately, the forward fan doesn't clear my DIMMs, but there is an interesting workaround. The way Noctua mounts these fans to the radiator, they can be mounted higher and moving the fan up half of an inch up did the trick. Everything fits and works quietly. The only downside was the brown fans and rather than replace these, I mounted a 120mm Phanteks Lux RGB fan frame which plugs into the Aura port on the motherboard and computer case to provide an integrated look and mask that brown fan. As for cooling, I ran some overclocking stress tests on my system and the Noctua air-cooler kept the CPU below 70 degrees Centigrade while overclocking around 5 GHz on the CPU. Your results will vary based on overall airflow through your case, I am using the Phanteks Evolv X with the glass doors closed and having great airflow. One note of caution - the NH-U12A is tall, and by offsetting the front fan higher, you may have clearance problems in a narrower computer case. This offset works fine inside the Evolv X.;;Reviewed in the United States on May 1, 2019;;5.0 out of 5 stars;;One of the best air-coolers on the market;;Michael C. Benolkin;;;I 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 you're 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.;;Reviewed in the United States on April 20, 2019;;5.0 out of 5 stars;;Amazing Air Cooler; a little expensive for an air cooler;;atavax

The only downside was the brown fans and rather than replace these, I mounted a 120mm Phanteks Lux RGB fan frame which plugs into the Aura port on the motherboard and computer case to provide an integrated look and mask that brown fan. As for cooling, I ran some overclocking stress tests on my system and the Noctua air-cooler kept the CPU below 70 degrees Centigrade while overclocking around 5 GHz on the CPU. Your results will vary based on overall airflow through your case, I am using the Phanteks Evolv X with the glass doors closed and having great airflow. One note of caution - the NH-U12A is tall, and by offsetting the front fan higher, you may have clearance problems in a narrower computer case. This offset works fine inside the Evolv X.

Amazing Air Cooler; a little expensive for an air cooler
I 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 you're 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.

Not impressed...
I was beyond excited to get the U12A to replace me U12S. That excitement quickly dwindled as I only saw a 1C drop in delta temp compared to my U12S (which I already had the new A12 fans on). I think this cooler will only be an improvement if you are not already using A12 fans.

Good gear
Switched to buying this instead of the nh d15, for my first build, for its supposedly comparable cooling in a smaller form factor. The less weight hanging off of a vertically mounted mobo the better. Mounting is easy...apply the backplate through the pre drilled holes around the cpu and screw in the spacers and hardware on the front (AMD & Intel hardware both included) . Throwing the heatsink on was a bit fiddly as you cant feel if you are seated correctly due to the spring tension on the screws nor can you see very well. Not a big deal...just dont fully tighten one side. Get both screws to catch before screwing both sides down. Fan mounting is intuitive. If you have tall memory the fans can mount as high as you like to accommodate as long as the heatsink isnt in the way. (De Wae) My i9 9900k took a modest OC to 4.7 using liquid metal instead of thermal paste in a well ventilated case with noctua 140mms moving air around. The cpu idles at 33-37c. AIDA64 trial version stresses my cpu to 100% usage and indicates about 70c. Looks like a success.

I'm able to see my rgb RAM sticks again!
I've always wanted the cooling power of a top-of-the-line Noctua cooler but didn't 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!

Awesome Performance with a Small Footprint
Does exactly what it was designed for. D15 performance in a smaller footprint. Fans are super quiet, even in a open air case and at 2000rpms, it’s very quiet. Best part, it’s fits in my Core P3 now with the glass mounted. Old D15 cooler would only work with single fan in middle of towers. Could not get dual 140s with the Core P3 and with tall memory. If worried about space, this is the cooler to get. 8700k delidded @ 5ghz hits 65c after 2 hours of prime95 stress on this cooler. D15 got to 63-64c. So that is awesome for how small this cooler is. CONS - brown fans and no chromax covers for hearsink. Have not heard back from NOCTUA if those will be released anytime soon.

The NH-U12A gave me 1/4 - 3/8 inch (+) more room from my memory than the NH-U12S.
Like what was said before, priced high and if you own the NH-U12S - "Don't Upgrade if not gaming". The NH-U12S was way too close to my memory sticks, but the NH-U12A gave me 1/4 - 3/8 inch more room. Plus, I did drop 3C at idle and 4C at gaming. I am only running 1 fan (120mm Cooler Master Jet Flo) which pushes 95 CFM at 2000 rpms. Works great. I am controlling all 6 of my fans via my BIOS so no need for any speed-controlled cables connected to the fans. If the NH-U12A was just as close to the memory as the NH-U12S, I would have returned it the same day I received it. Overall, I love the NH-U12A cooler. Noctua needs to make a Chromax cover for this cooler. Update - 9 Apr 2019 While running the NH-U12A cooler since 29 Mar 2019. It has been a great addition to my PC. I am running a i7-8086K (4Ghz (5Ghz OC)), EVGA 1080 Ti SC2, EVGA Z370 Classified (gaming). My CPU is running on Auto settings (in BIOS) which allows the CPU multiplier to run the CPU from 4Ghz to 4.6Ghz when the system needs it without OC’ing. This allows me to run only 1 CPU fan. While gaming, my temps max out at 53C and 33C at idle as per MOBO CPU LED readout. If later, I decide to OC to 5Ghz I will install the second fan (DO NOT OC with 1 CPU fan). If you plan to game on your PC, upgrade to the NH-U12A if your PC case does not allow for the NH-D15. I had to return my NH-D15 because my case was just a bit smaller than the cooler. I could have kept the NH-D15 if I left the PC door off but it would have looked so wrong for so many reasons.

One of the best air-coolers on the market
When I was pulling together the components for my recent computer build, I was toying with the idea of water-cooling the I9 CPU, but opted to try air-cooling first. Enter the Noctua NH-U12A and the online reviews indicated that it was designed to provide better clearance over the taller RAM DIMMs on the market. When I test-fit this cooler onto the I9 mounted on an ASUS ROG Maximus XI Extreme motherboard, it looked like it would indeed mount nicely with some overlap of the RAM DIMM slots. Unfortunately, the forward fan doesn't clear my DIMMs, but there is an interesting workaround. The way Noctua mounts these fans to the radiator, they can be mounted higher and moving the fan up half of an inch up did the trick. Everything fits and works quietly. The only downside was the brown fans and rather than replace these, I mounted a 120mm Phanteks Lux RGB fan frame which plugs into the Aura port on the motherboard and computer case to provide an integrated look and mask that brown fan.
