Noctua NH-D12L Review

Do you really think Noctua needs any introduction? This company is top of the world and famous for providing best performing and quietest cooling solutions on the market. Noctua just released a new CPU cooler in the midst of the cooler series of NH-U12. On the lovers of compact size gaming enthusiasts they released a shorter version 120 mm of CPU cooler.

They can install this CPU cooler even within some cases of mini ITX form factor. You have NH-D12L as a CPU cooler for your rig on your table with the promise to deliver quiet cooling performance of your choice. With a reputation of amazing performance, exceptional quality, at ultra-low noise levels, Noctua remains a famous manufacturer due to their production of PC-cooling products. Let’s dive in, to know more about this amazing cooler!

Aesthetics & Design

If you have interest in PC DIY then you must know that the products of Noctua are very less controversial. Brown/beige hues can be the choice of both who love colors and also those who want simplicity. Regardless of the hues, the users want quality and durability which is simply too amazing. 

Every company has its own house of color schemes and trademarks. Like Gigabyte uses Blue and ASUS ROG prefers Red, we should also appreciate Noctua’s dilemma. Comes with a heatsink which is nickel-plated aluminum. There is a beige-brown NF-A12x25r fan that is placed between the 2 towers.

Furthermore, the CPU cooler is utilitarian in design and lacks visual nuances. And the heat pipes are exposed and there are no coverings or other gimmicks. Consists of a beige-brown heatsink with a fan. And the heatsink fins are straight and they do not bend just like the other lesser CPU coolers.

Noctua NH-D12L’s heat sink is large and high-quality and it has 38 tightly spaced fins which emit a lot of heat in a better way. And give the same performance even on a tiny area. This credit goes  to the pressure-optimized fans.

There are 5 heat pipes that are nickel-plated copper neatly soldered throughout the stack while passing through a smooth contact plate. And the product dimensions are‎ 4.45 x 4.92 x 5.71 inches and the weight is 1.96 Pounds. We recommend you to check its compatibility with your case before making the decision of its purchase.


So after a short review of the product you must want to know its specifications in detail. This is as good a product as the other manufactured by Nactua. Before making any decision you must know its specifications. Because only the base of its features you can determine whether it will suit your computer system or not.

More performance at lower height

Noctua NH-D12L is capable enough and even with its reduced height it can easily outperform other 92 mm CPU coolers. It can even surpass the 120 mm award winning flagship model NH-U12A. Additionally, you can get more performance, do not think it can not perform well because of its small size.

PWM support and Low-Noise Adaptors

This CPU cooler consists of a 120 mm NF-A12x25r fan and comes with PWM. So that is required to control speed automatically through the motherboard. It can perform well even under the heavy load and high temperature. 

Best of all, it performs silently in idle situations. If you use a low noise adapter it can reduce fan speed from 2000 to 1700 RPM. when you use a low noise adapter with supply it will give more quieter operations. 

Dual-fan options

The NH-D12L comes with the support of dual fans; you can use another Nh-A12x25r PWM fan for improved performance. You can install that fan on the rear or front of the fin stack. However, keep in mind that it will always come on the top of graphics RAM or I/O panel. 

SecuFirm2 multi-socket mounting system

Noctua’s SecuFirm2 mounting is a system that is used for easy, safety and quality installation of CPU coolers on your system. With the compatible socket you can straightforwardly install it. Also it comes with an upgrade kit so it can also be used for future sockets. If you install your cooler properly it will work perfectly even under heavy load. 

NT-H1 thermal compound

Noctua’s much-acclaimed NT-H1 is known as a pro-grade TIM solution which offers minimum thermal resistance, outstanding reliability and is easy to use. It is considered as a benchmark for premium quality thermal compounds. That is why enthusiast users choose it again and again.

You are ready to go!


A lot of the users face clearance difficulty while using a larger air CPU cooler. Especially if they are using a large sized cooler in a compact PC case. RAM clearance is not a big issue if you use your cooler with a single fan. With the single fan set up your CPU cooler will not overhang any DIMM slots.

But yes with a 2 fan configuration it can be a difficult story. If you put a second fan on the top of a slimmer tower of your cooler than RAM clearance gets in trouble. That is why it is necessary to adjust the second fan according to the space. However the best thing is that this cooler has 100 percent PCIe compatibility.

Even if you use it with a large sized graphics card for example ASUS RTX, there will still be a lot of room in between the CPU cooler and graphics card

Temperature Benchmark of NH-D12L

To fully determine the performance for this cooler we need to put in testing. So we can get the results whether it is right that Noctua claims or not. Let’s check out!

Test System

We selected Intel Core i9-12900K as our testing companion. And the other specifications that we using while testing are:

Board: MSI MAG B660 Tomahawk WiFi DDR4


Hard Drive: Intel S3500 128GB

RAM: Corsair Vengeance RGB PRO SL (16GB)

Power Supply: Corsair RMx850

While using these hardware components we tested NH-D12L in the idle and load temperature. We get the Delta results in the celsius. While in the idle situation at 305 RPM and the results are 9.4 degree celsius.

On the other hand, when we run our system under heavy load at 1148 RPM. we saw that the temperatures went to 38.8 degree celsius. The range of delta temperature is quite better, but keep in mind that lower temperature is always better. 

Single vs Dual Fan Configuration

You can use noctua NH-D12L either with single or dual fan, it is completely up to your choice and requirement of your system. You can use a dual fan by the use of push pull method. If we set up 1 fan at maximum RPM the temperatures roughly went to 53 degrees. 

While both fans are working on auto RPM there is a substantial temperature differential of 3 degrees. However when fans were at the maximum RPM the difference was only 2 degrees. If you are very concerned about the temperature of your system then a 2 fan setup can suit you better. 

Noise Levels

Serious gamers love to choose their computer system or want to do gaming in a peaceful environment. If your current gaming PC makes noise then it’s time to check it to an expert for the reduction of noise. On the other hand, a solution is that you go for a CPU cooler that not only maintains its heat and controls temperature but also operates quietly. 

And not as a better option as NH-D12L, it works effectively and without making noise. We test its noise level from a distance of 15 meter. on the different fan speed such as;

  • 25%
  • 50%
  • 75% 
  • 100%

At 25% fan speed, Noctua NH-D12L makes 35 dBA noise. At 50% PWM the noise level of this CPU cooler is 38 dBA. While running with 75% PWM the noise level will be 45 dBA. Furthermore, we also tested it on the 100 PWM and the noise level of NH-D12L was 51 dBA. These figures are not too bad, which means it performs well with less noise level. However, the lower noise level is always a better choice. 


If we talk about cooling-wise performance the NH-D12L  does outstandingly with a 90 Watts processor. The performance on the default clock frequency is amazing, we can say nothing more or nothing less. But in an overclocking situation of a processor on this heat-pipe is quite not a good idea. 


The price of NH-D12L is 115 dollars, which is not bad because it contains the NF-A12x25r PWM fan. And the retail price of its fan is 29.90 dollars on its own. Beside the fan it contains heatpipes too that are pricey too. In short this a very reasonable price and it justifly its price tag by delivering amazing performance. 

Pros And Cons Of Noctua NH-D12L


  • Dual Tower Asymmetrical Design
  • SecuFirm2 multi-socket Mounting System
  • Wide Range of Socket Compatibility
  • Noctua NF-A12x25r PWM Fan
  • Capable Performance
  • 5-Year International Warranty
  • RAM and PCIe Clearance 


  • Very Basic Aluminum Look
