Design and Aesthetics:


NH-L9x65

The NH-L9x65 features a low-profile design with a slim aluminum heatsink and a 92mm NF-A9x14 PWM fan. With a height of only 65mm, the cooler is compatible with a wide range of PC cases, including mini-ITX and HTPC builds. Aesthetically, the NH-L9x65 maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.

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:


NH-L9x65

This cooler is designed to be a typical Noctua cooler installation, which is easy to do and rather straightforward. This means that if you're new to installing a CPU cooler, there is little room to make a mistake. For AMD is uses the original AMD backplate. Only downside to the Noctua installation is that the cooler may stick to your CPU and given how the screws are setup, you can't slide the cooler off the CPU like other brands.

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:


NH-L9x65

The performance of the NH-L9x65 is suitable for most mainstream CPUs and everyday tasks. It has four heat pipes that efficiently transfer heat away from the CPU to the heatsink. While the cooler may not be the best choice for high-end CPUs with high TDPs or extreme overclocking scenarios, it provides adequate cooling for lower TDP CPUs, especially in small form factor builds with limited space.

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:


NH-L9x65

The 92mm NF-A9x14 PWM fan included with the NH-L9x65 is designed for quiet operation while maintaining good airflow for its size. Noctua fans are well-known for their excellent acoustic performance, and the NH-L9x65 is no exception. Users can expect quiet cooling even during low workloads, however due to it's limited cooling abilities, it may have to run louder moderate workloads or gaming sessions.

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.


Summary:


NH-L9x65

The Noctua NH-L9x65 is a compact and efficient air cooler that's well-suited for small form factor builds and systems with limited space. Its low-profile design, adequate cooling performance, and quiet operation make it an attractive option for those looking for a space-saving and reliable cooling solution.

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.
