Overview of the Products

The Thermalright Assassin X 120R SE V2 CPU Cooler is priced at $16.59, making it significantly more affordable than the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler, which retails for $45.90. This price difference of about 176% highlights a key consideration for budget-conscious users who still seek effective cooling solutions.

The Assassin X 120R SE V2 features a compact design, utilizing four 6mm heat pipes to enhance its cooling capabilities. In contrast, the Peerless Assassin 120 offers a more robust configuration with six heat pipes and a digital screen on its top cover, appealing to users who prioritize both aesthetics and performance.

Cooling Performance

In terms of cooling efficiency, the Peerless Assassin 120 stands out with its six heat pipes and a fan speed of 1850 RPM, which can move air at a rate of 88.89 CFM. This setup is designed for optimal heat dissipation, ensuring that high-performance CPUs remain cool under load.

On the other hand, the Assassin X 120R SE V2, with its four heat pipes and a maximum fan speed of 1550 RPM, achieves an airflow of 66.17 CFM. While effective, it may not match the cooling prowess of the Peerless model, especially for overclocked setups or demanding applications.

Noise Levels

Both coolers maintain a low noise profile, operating at a maximum of 25.6 dB(A). This is a commendable feature for users who prefer a quiet computing environment.

While both the Assassin X 120R SE V2 and the Peerless Assassin 120 utilize S-FDB bearings, which help reduce noise and increase durability, the overall design of the Peerless model, with its dual tower and dual fans, may offer more efficient cooling with minimal noise.

Design and Aesthetics

The design of the Peerless Assassin 120 is more visually striking, featuring a digital screen that displays real-time temperature data. This feature adds an element of modernity and functionality that can enhance the user experience.

Conversely, the Assassin X 120R SE V2, while functional, has a more traditional aesthetic. It includes RGB lighting, which can add flair to a build, but lacks the digital display that many users may find appealing in the Peerless model.

Compatibility

Compatibility is crucial when choosing a CPU cooler, and both models cater to a wide range of platforms. The Assassin X 120R SE V2 supports Intel sockets LGA1150 through LGA1851 and AMD AM4/AM5, making it versatile for various setups.

The Peerless Assassin 120 also supports the same Intel and AMD sockets, ensuring a broad compatibility range. This feature is essential for users who may upgrade their CPUs in the future, allowing them to retain the cooler without needing to purchase a new one.

Installation Process

Both the Assassin X 120R SE V2 and the Peerless Assassin 120 come with mounting hardware compatible with various sockets, simplifying the installation process for users.

However, the Peerless model's dual fans and more complex design may require a bit more attention during installation compared to the Assassin X 120R SE V2, which is more straightforward due to its simpler construction. This could be a deciding factor for users who prefer a hassle-free setup.

Price Comparison

The price difference between the two coolers is substantial, with the Assassin X 120R SE V2 priced at $16.59 and the Peerless Assassin 120 at $45.90. This 176% increase in price for the Peerless model may deter budget-conscious users, but it could be justified by the additional features and enhanced cooling performance.

For those who prioritize performance and aesthetics, the higher cost of the Peerless model may be worth it. However, users with simpler cooling needs may find the Assassin X 120R SE V2 to be a more sensible choice.

Which should you buy?

Ultimately, the choice between the Thermalright Assassin X 120R SE V2 and the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler depends on your specific needs and budget. If you are looking for an economical cooling solution and do not require advanced features, the Assassin X 120R SE V2 is an excellent choice at just $16.59.

However, if you prefer superior cooling performance, a modern aesthetic with a digital display, and are willing to invest more, the Peerless Assassin 120 priced at $45.90 will serve you well. Consider your priorities in cooling efficiency, design, and budget to make the best decision for your build.
