Dimension comparison
Overview of the Thermalright Peerless Assassin 120 Black
The Thermalright Peerless Assassin 120 Black CPU Air Cooler is designed for optimal cooling performance with a competitive price of C$54.90. It features a dual tower design with an effective heat dissipation area of 9600 cm², allowing for exceptional thermal management. The cooler's dimensions are 125mm x 135mm x 157mm, and it includes two PWM fans that operate at a maximum speed of 1500 RPM, generating an airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A).
The Peerless Assassin employs a unique AGHP technique with 6×6mm heat pipes, enabling effective cooling regardless of the cooler's orientation. It is compatible with a wide range of Intel and AMD sockets, including the latest LGA1700 and AM5. This makes it a versatile choice for various builds.
Overview of the Thermalright AXP120-X67 Black ARGB
The Thermalright AXP120-X67 Black ARGB Low Profile CPU Air Cooler is a more compact alternative, priced at C$38.79, making it a budget-friendly option. With dimensions of 123.5mm x 120mm x 67mm, it is specifically designed to fit into tighter spaces while still delivering solid cooling performance. The cooler features a single PWM fan that can reach speeds of up to 1800 RPM, providing a maximum airflow of 59 CFM, albeit at a slightly higher noise level of 26.1 dB(A).
This cooler also utilises 6×6mm heat pipes and includes ARGB lighting for aesthetic appeal. Its compatibility extends to a variety of Intel sockets, including LGA1700 and AM4. Despite its lower price, the AXP120-X67 is aimed at users who require effective cooling in a compact form factor.
Cooling Performance Comparison
When it comes to cooling performance, the Thermalright Peerless Assassin 120 Black outshines the AXP120-X67 due to its dual tower design and higher airflow capacity. The Peerless Assassin can achieve an airflow of 66.17 CFM, which is 7.17 CFM more than the AXP120-X67's maximum of 59 CFM. Additionally, the lower noise level of 25.6 dB(A) makes it a quieter option during operation.
Both coolers employ the AGHP technique, which helps mitigate the inverse gravity effect, enhancing cooling efficiency. However, the increased surface area and dual fans of the Peerless Assassin allow it to dissipate heat more effectively, making it a better choice for high-performance CPUs or overclocking scenarios.
Size and Compatibility
In terms of size, the Thermalright AXP120-X67 is more compact, standing at only 67mm tall compared to the 157mm height of the Peerless Assassin. This makes the AXP120-X67 a better fit for smaller cases or builds where space is a constraint. Its low-profile design is particularly advantageous for users looking to build compact systems.
Both coolers are compatible with a wide range of Intel and AMD sockets. The Peerless Assassin supports an extensive list of sockets, including modern options like LGA1700 and AM5, while the AXP120-X67 also supports LGA1700 and AM4. However, the Peerless Assassin's broader compatibility may provide additional flexibility for future upgrades.
Aesthetic Appeal
For users who value aesthetics, the Thermalright AXP120-X67 comes with ARGB lighting, which can enhance the visual appeal of a gaming rig. This feature allows for customization and synchronisation with other ARGB components, adding a modern touch to the build.
In contrast, the Peerless Assassin does not offer ARGB lighting, focusing instead on performance and functionality. The aesthetic aspect of the Peerless Assassin leans more towards a classic cooling design without additional lighting effects. Those prioritising aesthetics may prefer the AXP120-X67, while performance-focused users may lean towards the Peerless Assassin.
Noise Levels
The Thermalright Peerless Assassin operates at a maximum noise level of 25.6 dB(A), making it a quieter option compared to the AXP120-X67, which can reach up to 26.1 dB(A). While the difference in noise levels is minimal, it can be noticeable in a quiet environment, especially during demanding tasks like gaming or rendering.
Both coolers are designed to maintain acceptable noise levels, but the Peerless Assassin's slightly lower dB rating could make it more appealing for users who are sensitive to noise or prefer a quieter PC experience.
Price Point
The Thermalright AXP120-X67 Black ARGB is priced at C$38.79, making it a more affordable option for budget-conscious consumers. In comparison, the Peerless Assassin is priced at C$54.90, reflecting its enhanced performance capabilities and dual fan setup.
While the AXP120-X67 is a compelling choice for those who need a cost-effective cooling solution, the additional investment in the Peerless Assassin may be justified for users seeking superior cooling performance and compatibility with high-end CPUs.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Black and the AXP120-X67 Black ARGB ultimately depends on your specific needs and preferences. If you require exceptional cooling performance, particularly for high-performance CPUs or overclocking, the Peerless Assassin is the better choice due to its dual tower design and higher airflow capability.
Conversely, if you are looking for a more compact cooler with aesthetic features like ARGB lighting and a lower price point, the AXP120-X67 is a solid option. Consider your case size, cooling requirements, and budget when making your decision.
