Compare: AK620 vs AK400

Design and Aesthetics:

AK620

The AK620 boasts a dual-tower layout with two reasonably-sized aluminum heatsinks and a couple of FK120 PWM fans. Its design ensures excellent heat removal, allowing it to tackle even the most powerful processors. In terms of appearance, this cooler sports a sleek black top, two black fans, and a silver aluminum radiator, lending a refined look to any computer setup.

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:

AK620

The AK620 has DeepCool's more modern installation designs as of 2023, which has more components than most for an easy install. The backplates are held down by single hand screwed nuts that also serve to hold the mount from the other side. This makes it easy to place the backplate correctly during the installation. The remaining portion of the install is similar to that of Noctua's typical installation, which makes it easy, but also can make the uninstallation challenging if the thermal paste sticks well to the CPU.

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:

AK620

The AK620 delivers remarkable performance due to its six heat pipes that effectively move heat from the CPU to the extensive fin array on the heatsink. It is compatible with a variety of processors, even high-end ones with high TDPs. This cooler can handle challenging workloads and extensive overclocking, making it an appealing cooling option. For those seeking Noctua-like performance without breaking the bank, the AK620 is a strong contender.

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:

AK620

A notable feature of the AK620 is its relatively quiet performance. The two 120mm FK120 PWM fans included are designed to deliver optimal airflow while maintaining low noise levels. Although this cooler might be louder than some alternatives of a similar size, its effective cooling makes it a strong candidate for your system. However, it's worth mentioning that some users may experience increased fan noise at mid RPMs occasionally.

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:

AK620

The AK620 is a high-performance cooler with a dual-tower design, six heat pipes, and two FK120 PWM fans that effectively dissipate heat, making it suitable for powerful processors and demanding workloads. Its sleek appearance features a black top, black fans, and a silver aluminum radiator, adding a refined touch to any computer setup. While the cooler generally operates quietly, it may be louder than some similar-sized alternatives, and occasional increased fan noise at mid RPMs is possible. Nevertheless, the AK620 is an appealing choice for those seeking top-tier performance on a budget.

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.
