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.

Peerless Assassin 120

The Peerless Assassin 120 boasts a stylish design, featuring a sizable aluminum heatsink, gray fans, and a gray radiator top that conceals the heat pipes. Its two 120mm fans guarantee excellent airflow and effective heat dissipation. The contemporary and elegant aesthetic suits a variety of build themes, making it an appealing choice for budget-conscious PC enthusiasts. The closely related Peerless Assassin 120 SE provides a black color scheme with a less refined top surface.


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.

Peerless Assassin 120

This cooler installation is very similar to Noctua's typical installation, which is one of the easier installation setups. However, it also faces similar issues regarding uninstalling this cooler, where the cooler is unable to slide/twist off the cooler to break the thermal paste seal. This might be necessary if the thermal paste has a strong hold between the cooler and 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.

Peerless Assassin 120

Impressive performance is a standout feature of the Peerless Assassin 120 SE, thanks to its six heat pipes that efficiently transfer heat away from the CPU and into the expansive fin array of the heatsink. It is suitable for a wide range of processors, including high-end models with high TDPs. The cooler is capable of handling demanding workloads and significant overclocking, making it a an attractive cooling solution option.


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.

Peerless Assassin 120

One of the standout features of the Peerless Assassin 120 SE is its relative quiet operation. The two included 120mm TL-C12 PWM fans are designed for optimal airflow and low noise levels.
