Compare: NH-L9x65 vs AS500 Plus

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.

AS500 Plus

The Deepcool AS500 Plus features a sleek and minimalist design with a large aluminum heatsink, an eye-catching black finish, and a top cover with customizable RGB lighting. The AS500 Plus comes with two 140mm PWM fans that provide efficient heat dissipation and a striking appearance.

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.

AS500 Plus

The Deepcool AS500 Plus features a mounting system compatible with a wide range of Intel and AMD sockets, and as of 2023, it employs DeepCool's more modern installation designs. These designs include additional components for an easier installation process. The backplates are secured by single hand-screwed nuts that also serve to hold the mount from the other side, simplifying the backplate placement during installation. Comprehensive instructions and high-quality components make the process user-friendly and straightforward. The remaining part of the installation resembles Noctua's typical installation, which is easy to execute but may pose challenges during uninstallation if the thermal paste adheres well to the CPU.

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.

AS500 Plus

The AS500 Plus has five heat pipes that effectively transfer heat away from the CPU and into the large fin array of the heatsink. The dual 140mm PWM fans deliver optimal airflow and cooling performance while maintaining low noise levels, making it an ideal choice for a wide range of processors, including high-end models with high TDPs.

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.

AS500 Plus

The Deepcool AS500 plus is a louder than average cooler. The two included 140mm fans are designed for optimal airflow and low noise levels. Although, this cooler can be louder than some other coolers of similar size, the relative cooling makes this cooler a contender for your setup.

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.

AS500 Plus

Deepcool AS500 Plus is a high-performance air cooler that provides excellent cooling capabilities, quiet operation, and a visually appealing design. Its customizable RGB lighting and compatibility with a wide range of processors make it a popular choice for PC enthusiasts seeking a reliable and efficient cooling solution for their systems.
