Compare: AK400 vs NH-D15 G2

Design and Aesthetics:

AK400

The AK400 is a sleek and stylish air cooler that features a clean black top, complemented by a single 120mm black fan, designed for users who appreciate a minimalist aesthetic. The it's single-tower aluminum radiator efficiently dissipates heat, ensuring effective cooling for your CPU. This compact and unassuming cooler not only delivers efficient performance but also seamlessly integrates into a variety of PC builds, making it an ideal choice for those who value both form and function.

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:

AK400

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 difficult to place due to the mounting bracket doesn't secure through holes, but rather through notches for the AMD setups (This isn't a problem for Intel setups). 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 AG400.

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:

AK400

The AK400 delivers impressive cooling performance for its size, attributed to its four heat pipes that effectively transfer heat from the CPU to the extensive fin array on the heatsink. It is well-suited for up to moderate-level processors; however, it might not be the best choice for high TDP CPUs or those looking to overclock their systems.

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:

AK400

This CPU cooler offers average cooling performance and operates at a moderate noise level. While it may not be the quietest option on the market, it maintains a comfortable balance between cooling efficiency and acoustic performance. This cooler is suitable for users who are not particularly sensitive to noise and are seeking a cost-effective solution for maintaining stable temperatures in their systems without demanding top-tier cooling or silent operation.

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:

AK400

This cooler has a moderately difficult installation, especially for AMD CPUs, due to its unique mounting setup. The installation process is similar to the AG400. The AK400 has a compact design, moderate cooling performance, and above-average noise levels. With a sleek, minimalist aesthetic, the cooler is suitable for various PC builds, offering a balance between cooling efficiency and acoustic performance for users seeking cost-effective solutions without top-tier cooling or silent operation.

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.
