Design and Aesthetics:


Fuma 2 Rev. B

The Scythe Fuma 2 Rev. B features a dual-tower design with two slim aluminum heatsinks and a pair of 120mm Kaze Flex fans. This design ensures efficient heat dissipation and allows for compatibility with various system configurations, including those with tall RAM modules. Aesthetically, the Fuma 2 Rev. B has a sleek, modern appearance with a black and gray color scheme that complements a variety of build themes.

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 2 Rev. B

The Scythe Fuma 2 Rev. B comes with a mounting system that offers compatibility with a wide variety of Intel and AMD sockets. The installation process is relatively straightforward, thanks to the detailed instructions and high-quality components provided. This cooler employs a similar method to the Noctua installation, but with a slight alteration in the male and female connectors on the cooler's mounting system. This modification allows for easy installation and removal of the cooler. However, to ensure optimal cooling performance, it's essential to carefully follow the instructions and achieve proper mounting.

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 2 Rev. B

The performance of the Scythe Fuma 2 Rev. B is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin arrays of the heatsinks. It is suitable for a wide range of processors, including moderate to low level TDPs. The cooler may not be suitable for high levels of overclocking but it is a popular choice among enthusiasts for mainstream CPUs.

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 2 Rev. B

One of the key attributes of the Scythe Fuma 2 Rev. B is its moderate noise output. The dual 120mm Kaze Flex fans are engineered for maximum airflow and moderate noise levels. Users can anticipate quiet cooling under most workloads.

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 2 Rev. B

The Scythe Fuma 2 Rev. B is a high-caliber air cooler that offers exceptional cooling performance and quiet operation. Its dual-tower design and modern aesthetics make it an appealing choice for users in search of a dependable and efficient cooling solution for high-performance computing systems.

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.
