Design and Aesthetics:

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:

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:

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:

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. Although, this cooler can be louder than some other coolers of similar size, the relative cooling makes this cooler a contender for your setup.


A notable feature of the Peerless Assassin 120 is its comparatively quiet performance.

While it may be slightly louder than other coolers of a similar size, its impressive cooling capabilities make the Peerless Assassin 120 a strong contender for your PC setup.

The product's performance has been consistently praised by reviewers. Many have noted that it effectively keeps their CPUs cool even during demanding tasks, such as gaming or running CPU-intensive benchmarks.

The white variant has also been specifically praised for its visual appeal in predominantly white-themed setups.
