Overview of the Thermalright Peerless Assassin 120 Mini Black CPU Cooler
The Thermalright Peerless Assassin 120 Mini Black CPU Cooler is priced at $34.39, making it a budget-friendly option for users seeking effective cooling solutions. This cooler features 6 heat pipes utilizing AGHP technology, which enhances heat dissipation efficiency. The 120mm PWM fan operates at a maximum speed of 1500 RPM, delivering an airflow of 66.87 CFM while maintaining a noise level of ≤ 25.6 dB(A). Its compact design, measuring 125mm x 110mm x 135mm, is suitable for a variety of builds, particularly those with limited space.
This cooler is designed for compatibility with a range of AMD and Intel sockets, including AM4, AM5, and Intel's LGA series. The cooler's robust build, with a fully blackened aluminum body and copper base, adds an aesthetic appeal along with its functional capabilities. Overall, it offers a reliable cooling solution for budget-conscious gamers and PC builders.
Overview of the Thermalright Peerless Assassin 120 SE V2 CPU Cooler
In contrast, the Thermalright Peerless Assassin 120 SE V2 CPU Cooler is priced at $38.99, which is about 13% more expensive than the Mini Black model. This cooler features a dual tower design with 6 heat pipes and dual 120mm PWM fans, allowing it to operate at a higher maximum speed of 1850 RPM. This results in an impressive airflow of 88.89 CFM and a noise level of 29.5 dB(A), making it a more powerful cooling option.
Designed to support both AMD AM4/AM5 and Intel LGA1851/1700 platforms, the dual tower configuration enhances heat transfer efficiency, providing stable thermal performance during intense gaming or multitasking scenarios. The dimensions of this cooler are 125mm x 110mm x 155mm, slightly larger than its counterpart, which may influence its suitability for different PC cases.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright Peerless Assassin 120 SE V2 stands out due to its dual fan setup and higher RPM capabilities. With a maximum fan speed of 1850 RPM, it generates a greater airflow of 88.89 CFM compared to the 66.87 CFM of the Mini Black model. This difference in airflow translates to better heat dissipation, especially during high-load situations such as gaming or video rendering.
However, the Mini Black cooler operates at a lower noise level of ≤ 25.6 dB(A) compared to the SE V2's 29.5 dB(A). For users who prioritize quiet operations, the Mini Black may be more appealing, though it may sacrifice some cooling efficiency as a result. Overall, if maximum cooling performance is the objective, the SE V2 is the clear winner.
Design and Aesthetics
Both coolers exhibit a thoughtful design, but they cater to slightly different preferences. The Thermalright Peerless Assassin 120 Mini Black features a sleek, fully blackened aluminum body that offers a modern and minimalist look, making it suitable for various builds. Its compact dimensions also make it an excellent choice for smaller cases where space is at a premium.
On the other hand, the Thermalright Peerless Assassin 120 SE V2, with its dual tower design, presents a more robust appearance, which may appeal to users looking for a cooler that stands out in their setup. While both models maintain a professional aesthetic, the choice largely depends on whether a user prefers a minimalist design or a more substantial, dual-tower look.
Installation and Compatibility
When it comes to installation and compatibility, both models excel, supporting a wide variety of CPU sockets. The Mini Black is compatible with AMD’s AM4/AM5 and Intel’s LGA series including LGA 1150 through 1851, offering versatility for different systems. The cooler's mounting kit simplifies installation, making it accessible even for novice builders.
The SE V2 also supports the same AMD and Intel sockets, providing users with a practical upgrade option for current mainstream desktop builds. Its dual tower design, however, might require more space and care during installation, particularly in tighter cases. Ultimately, both products offer excellent compatibility, but the Mini Black’s compact design may provide an edge in easier installation for smaller builds.
Noise Levels
Noise levels are a critical factor for many users, especially those who prefer a quieter computing environment. The Thermalright Peerless Assassin 120 Mini Black operates at a maximum noise level of ≤ 25.6 dB(A), which is quite subdued and ideal for users who prioritize silent operation.
In contrast, the SE V2 runs at a maximum of 29.5 dB(A). While this is not excessively loud, it may be noticeable in quieter environments. For gamers or professionals who often work in silence, the Mini Black offers a significant advantage in maintaining a peaceful workspace without sacrificing too much in terms of cooling efficiency.
Price Comparison
The pricing of the two coolers reflects their design and performance differences. The Thermalright Peerless Assassin 120 Mini Black is available for $34.39, making it an attractive option for budget-conscious consumers. Meanwhile, the Peerless Assassin 120 SE V2 is priced at $38.99, which is approximately 13% more expensive.
This price difference may influence buyers' decisions based on their budget and cooling needs. For users who require high performance and are willing to pay a premium, the SE V2 is a stronger choice. Conversely, those looking for solid performance at a lower price point might find the Mini Black more appealing.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Mini Black and the Thermalright Peerless Assassin 120 SE V2 ultimately depends on your specific needs and preferences. If you are looking for a budget-friendly cooler that performs well in smaller builds and operates quietly, the Mini Black is an excellent option at $34.39. However, if you require superior cooling performance, especially for high-load tasks, and are willing to invest a bit more at $38.99, then the SE V2 is the better choice.
Consider your priorities, such as cooling performance, noise levels, and design preferences, to make the best decision for your build.
