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.

Assassin III

The Deepcool Assassin III sports a premium design with two large aluminum heatsink towers, connected by eight heat pipes that efficiently transfer heat away from the CPU. The cooler comes with two 140mm PWM fans that provide efficient heat dissipation and a striking appearance. The overall design is sleek and minimalist, with an attractive black finish that complements a wide variety of build themes.


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.

Assassin III

The Deepcool Assassin III features a versatile mounting system compatible with a broad range of Intel and AMD sockets, and the installation process is user-friendly and straightforward. Although there are more steps involved with this cooler's installation, the parts for both Intel and AMD are well-labeled, and the steps are intuitive and easy to follow without much difficulty. It's important to note that this cooler has a large mounting footprint, which may require some consideration in terms of case and RAM clearance. As a result, checking compatibility before purchasing is essential to ensure a hassle-free installation experience.




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.

Assassin III

The Assassin III's dual-tower design and eight heat pipes deliver exceptional cooling performance, making it suitable for even high-end CPUs with high TDPs. The two 140mm PWM fans ensure optimal airflow and cooling performance while maintaining low noise levels, providing an excellent balance between performance and acoustics.


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.

Assassin III

The Deepcool Assassin III fans are engineered to produce minimal noise during regular operation, and they can also be adjusted through the PWM control to find the perfect balance between cooling and noise for your specific needs. In most scenarios, the Assassin III operates at a low noise level, making it a suitable choice for users who value a quiet computing environment.


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.
