Design and Aesthetics:

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.

Install Notes:

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.

Cooling Performance:

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.

Noise Performance:

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.


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.
