From the brand


U12A

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 LGA115x and AM4

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. *

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.

5.0 out of 5 stars GREAT COOLER
Reviewed in Singapore 🇸🇬 on 15 December 2022
Smaller than a D15, perfect for a mid tower case with no clearance issues.
2 high performance A12 fans means a REALLY quiet cooler that performs well with my 13700K, maintaining high boost locks and high wattage throughout all tasks.

5.0 out of 5 stars The hidden gem in the Noctua range, NH-D15 performance in a smaller package.
Reviewed in the United Kingdom 🇬🇧 on 4 January 2021
I am running an AMD Ryzen 5800X and had the massive Noctua NH-D15S for a while and while it is an exceptional cooler it's absolutely massive (I was only able to have one fan installed on it otherwise it would have blocked the GPU fan below (see picture).

I was on the verge of ordering an AIO water cooler but by accident I stumbled upon the NH-U12A, initially thinking that it's yet another standard single tower cooler and would be a noticeable step down in performance due to its smaller size.

Noctua claims on the box that this cooler offers 140mm performance in a smaller 120mm package and naturally I was sceptical of this sort of claim, but it turns out it's completely true!

You can tell Noctua has thrown all their engineering and technology behind this to enable it to perform like it's bigger brother and they've achieved this by adding an additional heatpipe (7 compared to the 6 found on the NH-D15) as well as including two of their brand new NF-A12x25 fans in a push-pull configuration.

The supplied NF-A12x25 PWM fans are a game changer compared to anything I've tried before - the blades use a new material that allows them to extend the blades so there is practically no gap between them and the housing which increases the static pressure to help force air through heatsinks (and radiators). A new bearing/hub allows it to wind up all the way to 2000RPM at a noise level that you have to actually experience yourself to believe. You could easily have these running 1500-1800RPM and be as quiet or quieter than other fans running just 1000-1200. I believe this fan would outperform even 140mm fans for airflow and static pressure.

As with all Noctua coolers, the supplied mounting kit for AMD and Intel processors is really easy to install and provides a secure mount. One particular highlight is the screws that screw the heatsink down to the mounting platform have a spring and a 'hard stop' to ensure you get the perfect mounting pressure with no risk of overtightening (once the screw stops turning it's done). It's also supplied with Noctua's excellent NT-H1 thermal paste and a handy screwdriver.

I ran the Cinebench R23 multicore benchmark with my existing NH-D15S and got a maximum temperature of 81-82C (room temperature 24C) and then installed the NF-U12A and ran the same benchmark and got the SAME temperatures and same benchmark score.

So if you think the NH-D15 is too big or just won't fit in your case, don't hesitate to consider this instead, you really don't have to compromise!

PROS:
1. Same performance as the massive NH-D15S
2. Compact footprint and is horizontally offset to stay clear of the memory
3. Typical Noctua quality
4. Simple to install AMD/Intel mounting kits provided (including Screwdriver!). Very secure fitting
5. 7 Heatpipes
6. Supplied with the incredible new NF-A12x25 fans
7. Excellent airflow through the heatsink due to the fans
8. Supplied with a tube of the excellent NT-H1 thermal paste
9. Supplied with 2 different speed adapters (if you can't use PWM)

CONS:
1. More expensive than the NH-D15 (although consider the fans cost £25+ individually!), although in my opinion you get what you pay for.

Shipping - From supplier to the philippines took about 5 days, which is incredibly fast considering we're under lockdown.

Packaging - the u12a unit was well packed by noctua. But the noctua box was put into another slightly larger delivery box. There is no bubble wrap in between, it's a good thing the item performed as expected out of the box.

Installation - incredibly easy to install.. the hard part was removing the components of your motherboard to swap out the mounts.

Performance - I live in the philippines, so ambient temperature here reaches about 37 to 42° with the AC off.

My system specs is as follows.

Case : Trendsonic Rainbow
PSU : Thermaltake 630w modular
MoBo : Asus Prime B250 M-A
Processor : Intel i7 - 7700k(Stock)
Memory : 2x 8gb DDR4 Kingston HyperXFury
@2400mhz
HDD : Seagate 160gb
GPU : GeForce RTX 2060 Super
Thermal paste used : Kryonaut Thermal Grizzly

Intake fans :
2x Noctua NF A12x25 120mm Fans
Exhaust Fans
1x Trendsonic Case fan(Rear)
1x Coolermaster HyperEvo 212 Fan(Top) - yes i converted it to a case fan.

Comparison
(From Hyper evo 212 to NH U12A)

Idle Temps

Hyper Evo - 40 to 42°
Noctua - 40 - 42

At Load
I ran TLoZ BotW via Cemu 4k res @60fps in 1 hour. (yup, definetly not the best benchmarking tool)

Hyper evo - 82 to 83°(Average)
Noctua - 71 to 73 °(Average)

Noise - yup, silent as it can ever be, noctua's claims is legit.

Personal Opinion - I think the NH u12a is a great cooler and all, but also be aware of your ambient temperature, I believe this cooler will work best in a air-conditioned environment.

But alas, to shave off 10° from the load temperatures under room temps? I'm sold!!! Thank you seller!

Except for the packaging I'd rate this buy 9.5/10.

Oh, and linus tech tips sent me here.

Just 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 :)
Edit: I added two 2000 RPM Noctua NF-F12 iPPCs fans instead of stock NF-A12s, they are a bit noisy in full speeds, but man, Noctua is amazing :D. Apart from that, I have had 4 redux case fans and my case is so cool
