Performance Comparison

In terms of cooling performance, the Peerless Assassin outshines the Assassin King due to its dual fans and six heat pipes. The Peerless Assassin’s fan can reach speeds of 1850 RPM, compared to the 1550 RPM of the Assassin King, allowing it to move more air and potentially lower CPU temperatures more effectively.

With an airflow rating of 88.89 CFM, the Peerless Assassin provides approximately 34% more cooling capacity than the Assassin King’s 66.17 CFM. This enhanced airflow can be crucial for users who engage in heavy gaming or CPU-intensive tasks. Thus, if performance is your top priority, the Peerless Assassin is the superior choice.

Aesthetic Considerations

Aesthetically, both coolers cater to different tastes. The Thermalright Assassin King features a striking white design complemented by ARGB lighting, making it suitable for builds with a lighter color scheme. Conversely, the Thermalright Peerless Assassin has a sleek black finish, accented by its digital screen, which may appeal to those looking for a more modern, professional look.

The digital screen on the Peerless Assassin not only enhances its visual appeal but also provides real-time information about the cooler’s performance. This feature can be particularly appealing for tech enthusiasts who enjoy monitoring their system's metrics. Therefore, the choice between these two comes down to personal preference regarding color and additional features.

Compatibility and Installation

Both coolers offer broad compatibility with various CPU sockets, including Intel and AMD platforms. The Assassin King supports Intel sockets such as LGA1700, 1150, 1151, and AMD AM4, while the Peerless Assassin extends compatibility to additional sockets, including LGA1851 and various AMD configurations.

Installation for both coolers is straightforward, with included mounting clips that facilitate easy setup. However, the slightly larger dimensions of the Peerless Assassin, with its height of 162 mm compared to the Assassin King’s 148 mm, may require more consideration regarding case space. If you have a compact build, this may be a point to ponder.

Noise Levels

In terms of noise performance, both coolers operate at a maximum noise level of 25.6 dB, which is commendable for cooling solutions in this category. This low noise level means that regardless of which cooler you choose, you can expect a quiet operation, which is particularly beneficial for those who value a serene computing environment.

However, it’s essential to consider that while the noise levels are similar, the Peerless Assassin, with its higher airflow and fan speed, may produce slightly different sound dynamics under load. For users sensitive to sound, this could be a factor worth considering, even if the decibel ratings are the same.

Price Evaluation

The Thermalright Assassin King is significantly more affordable at $19.82 compared to the Peerless Assassin's price of $45.90. This price difference of about $26 translates to approximately 130% more for the Peerless Assassin. If budget constraints are a priority, the Assassin King offers excellent value without compromising essential cooling performance.

However, the price of the Peerless Assassin reflects its advanced features, superior cooling capabilities, and aesthetic enhancements. For users willing to invest more for better performance and additional features, the Peerless Assassin may justify its higher cost.

Which should you buy?

Choosing between the Thermalright Assassin King 120 SE White ARGB and the Thermalright Peerless Assassin 120 Digital ARGB Black ultimately depends on your specific needs and preferences. If you’re looking for a budget-friendly option that still delivers solid performance and aesthetic appeal, the Assassin King is an excellent choice at $19.82.

Conversely, if performance, advanced features, and aesthetics are your top priorities, the Peerless Assassin, priced at $45.90, offers superior cooling capabilities and a modern design. In summary, evaluate your budget and performance needs to make the best choice for your setup.
