Compare: AK620 vs AXP90-X47 Full Copper

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.

This cooler features a sleek, low-profile design, making it an excellent choice for compact builds where space is a priority. Its copper construction not only enhances thermal performance but also adds a distinctive look that stands out in any setup.

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.

AXP90-X47 Full Copper

Installing this cooler is more involved than a standard cooler due to its low-profile design, which requires it to be screwed in from behind rather than from the top, as is common with most coolers. While the installation is relatively easy if the motherboard is not yet secured in the case, it can be challenging if you attempt to install it with the motherboard already mounted. Additionally, the cooler's brackets are attached via screws that need to be removed and swapped depending on the CPU you're using.

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.

Given its compact size, it’s no surprise that this cooler won’t top the charts in cooling performance. However, it delivers impressive efficiency for its form factor, outperforming stock coolers of similar size.

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.

AXP90-X47 Full Copper

With its high-speed 2700 RPM single fan, this cooler has the potential to produce higher noise levels than typical models. However, given its compact size, it's expected to become audible when delivering high-performance cooling.

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.

AXP90-X47 Full Copper

This cooler’s sleek, low-profile design makes it an excellent choice for compact builds where space is a priority. Its copper construction enhances thermal performance while adding a distinctive look to any setup. While it won’t compete with larger coolers in raw cooling power, it outperforms stock coolers of similar size. The high-speed 2700 RPM fan can produce noticeable noise under heavy loads, which is expected given its compact form factor. Installation is more involved than standard coolers, requiring mounting from behind rather than from the top, making it easier to install before securing the motherboard in the case. Additionally, its brackets must be swapped depending on the CPU, adding an extra step to the process.
