Design and Aesthetics:


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.

NH-D15 G2

This cooler is quite large and showcases Noctua's signature design, appealing to diehard PC builders who don't want to compromise on cooling performance. The NH-D15 G2 closely resembles the previous generation, with a few updates. This version features eight heat pipes and offset depths on the two heatsinks


Install Notes:


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.

NH-D15 G2

The NH-D15 G2 retains the same installation design as its predecessor, with the addition of a new bracket that allows for offset mounting on AM5 CPUs. The installation process is straightforward, guided by clear instructions that adhere to industry standards for top-tier coolers. However, the cooler's large size may pose challenges when maneuvering it within the case.




Cooling Performance:


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.

NH-D15 G2

The Noctua's NH-D15 G2 cooler is hard to beat in terms of cooling performance, even outperforming AIOs from various other brands—a result expected given its larger size. However, when compared to the previous generation, its performance is on par, offering little improvement.


Noise Performance:


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.

NH-D15 G2

Compared to the average cooler, the Noctua NH-D15 G2 is louder than most on the market. However, when performance is evaluated on a noise-normalized basis, this cooler is tough to beat, offering excellent cooling for a given noise level. This means you can keep your cooler quiet when needed, while still having the headroom to increase the speed for enhanced cooling performance.


Summary:


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.

NH-D15 G2

The Noctua NH-D15 G2 retains the familiar installation design of its predecessor, with the addition of a new bracket for offset mounting on AM5 CPUs. While its large size may make installation a bit challenging, the process is straightforward, with clear instructions that meet industry standards. The cooler's substantial size is matched by its performance, offering exceptional cooling that even surpasses many AIOs from other brands. Although its performance is on par with the previous generation, the NH-D15 G2 still delivers excellent cooling, particularly when considering noise levels. Despite being louder than the average cooler, it excels in noise-normalized performance, allowing users to maintain quiet operation while having the flexibility to ramp up speed for maximum cooling when needed.
