Compare: NH-D15 chromax.Black vs AK400

Design and Aesthetics:

NH-D15 chromax.Black

The NH-D15 chromax.Black features a dual-tower design with two large aluminum heatsinks and a pair of Noctua's 140mm NF-A15 PWM fans. The cooler's design allows for superior heat dissipation, making it capable of handling even the most demanding processors. Aesthetically, this version of the NH-D15 adopts a black color scheme, providing a sleek and modern appearance that complements various build themes.

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.

Install Notes:

NH-D15 chromax.Black

The NH-D15 features Noctua's SecuFirm2 mounting system, ensuring compatibility with numerous Intel and AMD sockets. The installation process is made easy with the help of clear instructions and top-notch components. Additionally, Noctua includes a tube of their high-quality NT-H1 thermal compound for optimal heat transfer between the CPU and heatsink. However, the cooler's large size may make it challenging to maneuver around when installed within the case.

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.

Cooling Performance:

The performance of the NH-D15 is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin arrays of the heatsinks. It is suitable for a wide range of processors, from mainstream CPUs to high-end models with high TDPs. The cooler can handle high levels of overclocking and provides reliable cooling under demanding situations, making it a popular choice among enthusiasts. If this cooler can't handle the CPU's heat, then you will have to move to AIO coolers.

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.

Noise Performance:

One of the standout features of the NH-D15 is its quiet operation relative to its performance. The two included 140mm NF-A15 PWM fans are designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-D15 is no exception. Users can expect quiet cooling even during intense workloads or gaming sessions. Additionally, the Low-Noise Adaptors (LNA) connectors included can be used to reduce the fan's speed, further reducing the cooler's noise.

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.

Summary:

NH-D15 chromax.Black

The NH-D15 cooler offers easy installation with Noctua's SecuFirm2 mounting system, compatibility with numerous Intel and AMD sockets, and high-quality components. Featuring a dual-tower design, two large aluminum heatsinks, and a pair of 140mm NF-A15 PWM fans, it provides exceptional performance and heat dissipation for a wide range of processors, including high-end models with high TDPs. The NH-D15 chromax.Black version boasts a sleek black color scheme, and despite its large size, the cooler operates quietly during intense workloads or gaming sessions, with Low-Noise Adaptors available for further noise reduction.

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.
