Overview of the Products

The Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler is priced at $22.90, while the Thermalright Peerless Assassin 120 SE V2 CPU Cooler costs $38.99, making the Assassin X about 41% cheaper. Both products are designed for effective cooling solutions but target slightly different user needs. The Assassin X features a single tower design with a PWM fan, while the Peerless Assassin employs a dual tower design with dual fans, catering to users looking for enhanced cooling performance.

Cooling Performance

When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE V2 stands out with its dual tower design and 6 heat pipes, which are engineered to improve heat transfer efficiency. Its dual 120mm PWM fans can run at a maximum speed of 1850 RPM, balancing airflow and cooling performance during high-load scenarios. In contrast, the Assassin X has a single fan with a maximum speed of 2000 RPM. However, it only has 4 heat pipes, which may limit its overall heat dissipation capabilities in comparison to the Peerless model.

Compatibility

Compatibility is a strong point for both coolers, but the Peerless Assassin takes the lead. It supports both AMD AM4/AM5 and Intel LGA1851/1700 platforms, making it versatile for a wide range of modern desktop builds. The Assassin X also supports AMD AM4/AM5 and Intel LGA1700/1851/1150/1151/1200, but its broader range of compatibility is somewhat overshadowed by the design and performance benefits of the Peerless Assassin.

Design and Aesthetics

In terms of aesthetics, the Thermalright Assassin X features a digital screen on its top cover, enhancing its visual appeal and allowing for customizable ARGB lighting synchronized with the motherboard. This adds a level of personalization that many users appreciate. The Peerless Assassin, while still visually appealing, lacks such a feature, focusing instead on a robust dual tower design that prioritizes performance over flashy aesthetics.

Noise Levels

Noise levels can significantly impact the user experience, especially during intense gaming or multitasking sessions. The Assassin X is designed with noise reduction in mind, featuring silicone corner pads to minimize vibrations and reduce noise. While specific decibel levels are not provided for the Assassin X, the Peerless Assassin operates at a noise level of 29.5 dBA at maximum RPM. This makes the Assassin X potentially quieter during operation, although users may need to consider the performance trade-off.

Installation

Installing CPU coolers can be a daunting task for some users, and both products have their unique installation processes. The Thermalright Assassin X comes with a straightforward installation method, designed to be compatible with most cases without sacrificing heat dissipation performance. The Peerless Assassin, being a dual tower cooler, might require more space and careful handling during installation to ensure optimal placement. Users should assess their case dimensions and comfort level with installation complexity before making a choice.

Price Comparison

Price is an important factor when selecting a CPU cooler. The Assassin X is priced at $22.90, significantly lower than the Peerless Assassin’s $38.99 price tag. This represents a difference of about $16.09, making the Assassin X about 41% more affordable. For budget-conscious consumers looking for decent cooling performance without breaking the bank, the Assassin X offers a compelling value proposition.

Which should you buy?

In conclusion, the choice between the Thermalright Assassin X 120R and the Peerless Assassin 120 SE V2 ultimately depends on your specific needs and priorities. If you are looking for a budget-friendly option with decent performance and customizable aesthetics, the Assassin X is a strong contender. However, if you prioritize superior cooling performance and are willing to invest more for dual tower technology and enhanced heat dissipation, the Peerless Assassin would be the better choice. Each cooler has its strengths, making either a worthy addition to your setup based on your unique requirements.
