After reviewing the Noctua NH-D15S, we’re back with another review, this time of the Noctua NH-U12A The Noctua NH-U12A has been a strong competitor for Noctua, and with such a high profile, Noctua was compelled to release the cooler in the series. With an MSRP of $120, the cooler is, of course, more costly than the Noctua NH-D15 cooler

In the series, the Noctua NH-U12A is completely black from head to toe, and owing to a revised back-plate, it provides a wide variety of socket compatibility for both Intel and AMD. In comparison to the Noctua NH-U12S, the NH-U12A has a 37% larger surface area, 2x NF-A12x25 PWM fans, and seven copper heat pipes for optimal performance.

A Closer Look At The Noctua NH-U12A

With all of the extras out of the way, it’s time to focus on the Noctua NH-U12A The NH-U12A, like every other Noctua cooler, is an award winner in its own right. It is designed to provide additional RAM and PCIe clearance while also being convenient for those who have smaller PC cases.

The Noctua NH-U12A, like the Noctua NH-D15S, features an asymmetrical design that allows for better user compatibility. One of the best things about this cooler is its dual NF-A12 PWM fans, which have made it a true award winner. That’s because, the NF-A12 Fans are a work of art with their incredibly quiet and optimum airflow.

Noctua has also ensured that quality is maintained by introducing the newest SecuFirm multi-socket mounting technology, which is not only sturdy but also compatible with a broad range of Intel and AMD sockets.

One thing I noted while reviewing the Noctua NH U12A is that the company logo is in the center of the single-tower cooler, with the seven copper pipes poking out. At the center of the tower, there is a circle-shaped cutout that provides access to the mounting screw using the screwdriver provided for easy installation. The heat pipe tips at the top measure roughly 6mm apiece and are quite elegant.

The heatsink contains 50 nickel-plated aluminum fins that are finished in a black color coating. Due to the 58mm depth of the NH-U12A compared to the 45mm depth of the NH-U12S, the newer Noctua NH-U12A boasts a 37 percent increase in surface area for greater heat dissipation than the Noctua NH-U12S.

NF-A12 Fans

If we were to review the Noctua NH U12A without paying attention to the fans, it would be a shame. Luckily, the Dual Noctua industrial grade 120mm NF-A12 fans are included with the Noctua NH-U12A The pull-push fan arrangement comes pre-attached to the tower.

Due to the increased diameter of the center, the fans may appear larger than other 120mm fans. The 9x blades of the Noctua NF-A12 fan have a greyish-textured surface, which Noctua refers to as Flow Acceleration Channels. Additionally, anti-vibration cushions are also installed on all eight corners.

Noctua NH U12A Installation

The Noctua NH-U12A is easy to install. Before installing your CPU, make sure it is free of any previous paste residue. You may do this by swiping some rubbing alcohol over it.

Check that you’re using the right screws and brackets for your socket before you begin. After that, use the NM-ICS1 clip-on spacers to secure the bolts on the backplate, then firmly attach the backplate to your Motherboard in the right spot.

Attach the mounting bars and tighten them with the four NM-ITS1 thumbscrews, ensuring a tight and robust connection (not too strong).

Apply enough thermal paste to the cooler and place it on the mounting brackets without the fan. Next, secure the spring-loaded screws and tighten them with the included screwdriver for easy access. Remember that the screws must not be overtightened.

Noctua NH U12A Clearance

Clearance is usually an issue with air coolers, but the Noctua NH-U12A is an exception, even with both fans mounted. Thanks to its asymmetrical design, RAM clearance was not an issue, and we were able to utilize all DIMM slots on our motherboard.

Even though we used a big card, the NVIDIA GeForce RTX 3070 Ti, PCIe clearance was not an issue, and we were able to plug everything together fairly easily.

The cooler stands around 158mm tall. So, keep in mind that height can be an issue when trying to make room for DIMM slots or the motherboard IO shroud. However, the Thermaltake View 71t didn’t have a problem with height in our tests, but users with smaller cases might want to think about it.

Noctua NH-U12A Temperature Benchmarks

We had to put the Noctua NH-U12A through a series of tests to discover whether it was indeed an award-winning cooler. The tests were carried out within the Thermaltake View 71t, which has three intake fans on the front. We also put an exhaust fan at the back.

In terms of paste, the original Noctua thermal paste that came with the NH-U12A was utilized.

Test System

The latest Intel Core i9-12900K will be our friend during the testing; the complete specs are as below:

Testing Methodology

  • We set the i9-12900k voltage to 1.15V, P-Cores to 4.9 GHz, and E-Cores to 3.9 GHz in BIOS. This way, we allowed the comparison with simple heatsinks by forcing consumption of around 140W.
  • We carried out the test in Aida64 with the processor and memory boxes activated for 5 minutes.
  • For the ranking, delta temperatures are used between the ambient temperature and the corresponding test.

For the thermal testing, the Noctua NH-U12A was pitted against some major names. As seen in the graphs above, the NH-U12A was far from remarkable, coming dangerously close to edging out the 240mm AIO coolers. The cooling performance of the Noctua NH-U12A was demonstrated in two phases: Max and PWM.

In the Max phase, we obtained roughly 44.1° degrees on a complete CPU stress test, demonstrating the excellent cooling ability of the Noctua NH-U12A

Comparison With Other Premium Coolers

The Noctua NH-U12A, like the Noctua NH-D15/S, competes with other AIO coolers on the market. In our review, we compared the Noctua NH-U12A to some of the most well-known 240mm AIO coolers on the market, and we came to the conclusion that it is a worthy rival.

We compared the Noctua NH-U12A against 240mm AIOs such as the Thermaltake Toughliquid 240 ARGB and the ARCTIC Liquid Freezer II 240 A-RGB, and the results showed that the Noctua NH-U12A is rather amazing. The Noctua air cooler was almost as good as the high-end 240mm AIOs.

With the results in hand, customers must pick whether they want to go the way of an all-black air cooler with remarkable cooling capabilities or any 240mm RGB AIO cooler. We merely provide information, as we have always stated, and it is entirely up to the user.

Should You Get The Noctua NH-U12A

Noctua has launched its fan-favorite cooler once more, but this time in their all-new series. Noctua’s series delivers their greatest coolers in an all-black aesthetic for consumers that prefer stealthy aesthetics over RGB. The Noctua NH-U12A differs from the Noctua NH-U12A. In addition to the all-black color, it now has an asymmetrical design for greater and better clearance. With both fans mounted, the cooler weighs around 1220g and dimensions about 158x125x112mm. We also get two quality Noctua NF-A12 PWM fans.

Because Noctua is now soldering its heat pipes to the fins, the cooler offers outstanding cooling capabilities. The cooler is nickel-plated throughout, with a black finish on the outside. Additionally, the heatsink features around 50 fins and seven 6mm heat pipes that are cooled by two 120mm NF-A12 PWM fans.

Even with a big card like the NVIDIA GeForce RTX 3070 Ti, PCIe clearance was not an issue for us. Similarly, the asymmetrical design made sure that the cooler remained free from any RAM clearance issue. In fact, we utilized all DIMM slots on our motherboard without any hiccups.

In terms of fans, the NH-U12A comes with two NF-A12 PWM fans from Noctua. The all-black fans have a maximum rotating speed of 2000 RPM and a minimum rotational speed of 450 RPM. The fans are nearly silent owing to Noctua’s SSO2 bearing, which allows the blades to glide smoothly with the support of Flow Channels.

The SecuFirm2 mounting hardware has been installed on the Noctua NH-U12A As a result, we may use the NH-U12A with a variety of Intel and AMD sockets. The copper cold plate is nickel-plated and has a mirror finish on the top. If you carefully follow the installation instructions, you should have no trouble installing the cooler. The cooler does not arrive with pre-applied thermal paste, but we are given a tube of Noctua thermal paste.

The Noctua NH-U12A is no doubt expensive; you can grab one right now for a price tag of 120$ for the cooler and two fans. However, if you want to buy the fans alone, they would cost you 33$ each.

The cooler is clearly expensive, but we think that it is worth it. That’s because it offers impressive cooling capabilities, which are clearly comparable to the abilities of any 240mm AIO on the market. Not only that, but the noise levels are impressive, and the looks are also stealthy.
