Design and Aesthetics:


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.

Fuma 3

This cooler boasts a sleek appearance with a smooth top surface. Nonetheless, it's worth noting that the plastic covering the exposed heat pipes, while contributing to a polished appearance, is a rather subdued gray and lacks the eye-catching appeal of more vibrant or shiny options. This cooler is an excellent choice for those seeking exceptional cooling performance coupled with a more understated aesthetic.

Install Notes:


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.

Fuma 3

This cooler employs the standard mounting system commonly found in premium coolers. In comparison to the Fuma 2, the Fuma 3 has introduced a minor adjustment that enhances the ease of installation by preventing over-tightening, a feature absent in the Fuma 2. Overall, the installation process for this cooler is straightforward, and it has demonstrated improvements compared to previous Fuma iterations.

Cooling Performance:


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.

Fuma 3

The Fuma 3 is a mid-performance cooler offering moderate cooling capabilities. While it may not be suitable for high-heat CPUs, it's an excellent option for users who appreciate its aesthetic appeal and require effective cooling for CPUs with moderate thermal loads.

Noise Performance:


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.

Fuma 3

The dual 120mm Kaze Flex fans are engineered for maximum airflow and moderate noise levels. In terms of the noise-to-cooling ratio, it strikes a good balance, providing an average level of noise for the cooling performance it delivers.



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.

Fuma 3

The Fuma 3 cooler uses a standard premium cooler mounting system but adds a minor tweak from the prior generation for easier installation. Its sleek design features a subdued gray plastic top, making it suitable for users who prioritize both cooling performance and aesthetics, especially for mid-heat CPUs. Equipped with two 120mm fans, it strikes a balanced noise-to-cooling ratio.
