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.

Peerless Assassin 140

The Peerless Assassin 140 shares a similar design with other 140mm coolers from Thermalright, featuring two 140mm heatsinks paired with a 120mm fan at the front and a 140mm fan in the middle. The difference in fan sizes helps reduce RAM clearance issues, which are common with most 140mm air coolers. This model has a polished top and comes in an all-black design, though other color options may be available.


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.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler features installation components similar to many mainstream Thermalright designs, making it relatively easy to install. However, it encounters a challenge when uninstalling, as it doesn't allow for sliding or twisting to break the thermal paste seal. This can be problematic if the thermal paste creates a strong bond between the cooler and the CPU.




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.

Peerless Assassin 140

While the cooler offers similar peak performance to its competitors, its main advantage lies in its efficiency at lower RPMs, where it provides slightly better cooling. This translates to a noticeable edge in noise-to-performance ratio compared to smaller coolers, making it quieter under lower loads while still maintaining strong cooling capabilities.


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.

Peerless Assassin 140

Due to its larger fans, this cooler becomes more audible at higher RPMs. However, because the fans move more air, lower RPMs are generally sufficient for cooling under most moderate CPU loads, allowing for quieter operation without sacrificing performance.


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.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler is easy to install, thanks to its design resembling other mainstream Thermalright models, but it presents a challenge during uninstallation as it doesn’t allow for sliding or twisting to break the thermal paste seal. It features two 140mm heatsinks, a 120mm fan at the front, and a 140mm fan in the middle, which helps reduce RAM clearance issues common with larger coolers. While its peak performance is on par with competitors, it excels at lower RPMs, offering better cooling and a superior noise-to-performance ratio compared to smaller coolers. Although more audible at higher RPMs due to its larger fans, the slower speeds still provide sufficient cooling for most moderate CPU loads, ensuring quieter operation without compromising performance.
