Compare: AG400 BK vs NH-D15 G2

Design and Aesthetics:

AG400 BK

The AG400 series is a single tower 120mm CPU cooler that built upon DeepCool's legacy products but was stripped down for a streamlined and efficient package. It has a simple and clean design, with an aluminum tower and a single 120mm fan. This cooler comes in a variety of colors including black and white, so it matches most computer setups. Additionally, this cooler has RGB lighting which may fit for setups with a RGB focus.

NH-D15 G2

This cooler is quite large and showcases Noctua's signature design, appealing to diehard PC builders who don't want to compromise on cooling performance. The NH-D15 G2 closely resembles the previous generation, with a few updates. This version features eight heat pipes and offset depths on the two heatsinks

Install Notes:

AG400 BK

This cooler is moderately difficult to install and is more difficult than other DeepCool cooler installations. For AMD CPU's, the mounting setup can be given that the cooler doesn't secure through holes but rather through notches. For this reason, keeping the backplate flush against the motherboard while also keeping the install components in line may prove to be difficult and may require a second pair of hands. This also has a very similar installation to the AK400.

NH-D15 G2

The NH-D15 G2 retains the same installation design as its predecessor, with the addition of a new bracket that allows for offset mounting on AM5 CPUs. The installation process is straightforward, guided by clear instructions that adhere to industry standards for top-tier coolers. However, the cooler's large size may pose challenges when maneuvering it within the case.

Cooling Performance:

AG400 BK

It's designed to work with a wide range of modern CPU sockets and is able to dissipate heat quickly and efficiently. Although this cooler doesn't push out the best cooling performance, it does well for its size with performance slightly below the Noctua NH-U12S Redux. For this reason, this cooler is best for CPUs that need a moderate cooling solution.

NH-D15 G2

The Noctua's NH-D15 G2 cooler is hard to beat in terms of cooling performance, even outperforming AIOs from various other brands—a result expected given its larger size. However, when compared to the previous generation, its performance is on par, offering little improvement.

Noise Performance:

AG400 BK

This cooler has an above average noise profile, making it louder than most comparable air coolers. This means that you might experience more noise while your PC is running, which could be a drawback if you're sensitive to noise or prefer a quiet workspace. If having a quiet PC setup is important to you, it's worth considering other coolers with better noise profiles.

NH-D15 G2

Compared to the average cooler, the Noctua NH-D15 G2 is louder than most on the market. However, when performance is evaluated on a noise-normalized basis, this cooler is tough to beat, offering excellent cooling for a given noise level. This means you can keep your cooler quiet when needed, while still having the headroom to increase the speed for enhanced cooling performance.

Summary:

AG400 BK

The AG400 is an excellent choice to upgrade their CPU cooling solution. It has a sleek design with ARGB capabilities, helping create that look that sets you apart. However, this cooler isn't the most powerful cooling solution so it may not be best for all CPU's and it runs on the louder side. Overall, there is enough that sets this cooler apart that makes this cooler worth considering.

NH-D15 G2

The Noctua NH-D15 G2 retains the familiar installation design of its predecessor, with the addition of a new bracket for offset mounting on AM5 CPUs. While its large size may make installation a bit challenging, the process is straightforward, with clear instructions that meet industry standards. The cooler's substantial size is matched by its performance, offering exceptional cooling that even surpasses many AIOs from other brands. Although its performance is on par with the previous generation, the NH-D15 G2 still delivers excellent cooling, particularly when considering noise levels. Despite being louder than the average cooler, it excels in noise-normalized performance, allowing users to maintain quiet operation while having the flexibility to ramp up speed for maximum cooling when needed.
