Design and Aesthetics:


NH-U14S

The Noctua NH-U14S sports a sleek and minimalist design, featuring a slim single-tower heatsink attached with Noctua's iconic brown and beige color scheme. A 140mm fan is attached, further enhancing its understated appearance.

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.


Install Notes:


NH-U14S

The NH-U14S boasts a user-friendly mounting system that is compatible with a wide array of Intel and AMD sockets. Its straightforward installation process is facilitated by clear instructions and high-quality components.

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.




Cooling Performance:


NH-U14S

With its six heat pipes and an extensive fin array, the NH-U14S delivers exceptional cooling performance. It is more than capable of handling high-end processors, maintaining optimal temperatures even under heavy workloads.

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.


Noise Performance:


NH-U14S

Equipped with a 140mm NF-A15 PWM fan, the NH-U14S is designed for quiet operation. Striking a balance between cooling efficiency and noise, it is an ideal choice for users seeking a silent PC experience.

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.


Summary:


NH-U14S

The Noctua NH-U14S stands out as an excellent cooler, offering a simple yet attractive design, top-notch cooling performance, hassle-free installation, and impressively low noise levels. It is the perfect choice for those looking for a reliable and quiet cooling solution for their PC.

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.
