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.

NH-D15S

The NH-D15S features a dual-tower design with a large aluminum heatsink and one 140mm NF-A15 PWM fan. The asymmetrical layout of the cooler allows for improved clearance for RAM and PCIe slots, making it more versatile for different motherboard layouts. Aesthetically, the NH-D15S maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.


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.

NH-D15S

The NH-D15S comes with Noctua's SecuFirm2 mounting system, which provides compatibility with a wide range of Intel and AMD sockets. The installation process is straightforward, thanks to the clear instructions and high-quality components provided. Noctua also includes a tube of their premium NT-H1 thermal compound to ensure optimal thermal transfer between the CPU and heatsink.




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.

NH-D15S

The performance of the NH-D15S is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin array of the heatsink. 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. However, given this cooler only uses a single fan, this version of the NH-D15 doesn't perform as well as the NH-D15.


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.

NH-D15S

One of the standout features of the NH-D15S is its quiet operation. The included 140mm NF-A15 PWM fan is designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-D15S is no exception. Users can expect quiet cooling even during intense workloads or gaming sessions.


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.

NH-D15S

The Noctua NH-D15S is a versatile, high-performance air cooler that offers excellent cooling capabilities and quiet operation. Its asymmetrical, dual-tower design makes it suitable for various system configurations, and its exceptional build quality ensures long-lasting performance. For users seeking a reliable and efficient cooling solution, the NH-D15S is a top choice.
