Introduction
When it comes to CPU cooling solutions, the Thermalright Peerless Assassin 140 Black and the Thermalright AXP120-X67 Black ARGB are two strong contenders, each with unique features catering to different user needs. The Peerless Assassin is priced at C$54.90, while the AXP120-X67 offers a more budget-friendly option at C$38.79. This article will compare their designs, cooling performance, noise levels, compatibility, and overall value to help you make an informed decision.
Design and Build Quality
The design of a CPU cooler can significantly affect its cooling performance and compatibility. The Thermalright Peerless Assassin 140 Black features a twin-tower structure with a height of 158mm, making it suitable for large and medium-sized chassis. This design includes pure copper heatpipes and high-performance dual fans, which enhance its heat dissipation capabilities. In contrast, the AXP120-X67 is a low-profile cooler with dimensions of 123.5mm x 120mm x 67mm. This compact design is ideal for smaller builds or cases with limited vertical space. The choice between these two coolers will hinge on your case size and aesthetic preferences, especially since the AXP120-X67 also comes with ARGB lighting, adding a visual appeal.
Cooling Performance
Cooling performance is a critical factor for any CPU cooler. The Peerless Assassin boasts impressive heat dissipation thanks to its dual tower and dual fan setup. It can deliver an airflow of up to 66.17 CFM with a fan speed of 1500 RPM, providing substantial cooling for high-performance systems. On the other hand, the AXP120-X67, while being a low-profile option, achieves an airflow of 59 CFM at a slightly higher fan speed of 1800 RPM. Despite this, its smaller size may limit its overall cooling efficiency compared to the larger Peerless Assassin. If you are seeking maximum cooling for demanding tasks, the Peerless Assassin is likely the better choice.
Noise Levels
Noise levels are essential for users who prefer a quiet computing environment. The Peerless Assassin has a noise rating of ≤25.6 dB(A), making it one of the quieter options in its category. The AXP120-X67, while slightly louder, operates at ≤26.1 dB(A). The difference is minimal, but for those who are particularly sensitive to noise, the Peerless Assassin might be the more appealing option. Both coolers use PWM fans, which help regulate noise levels based on load, but the Peerless Assassin edges out with its quieter operation.
Installation and Compatibility
Ease of installation and compatibility with various CPU sockets are vital considerations. The Peerless Assassin supports a wide range of Intel sockets, including LGA1150 to LGA1851, as well as AMD's AM4 and AM5. This extensive compatibility makes it suitable for many builds. The AXP120-X67 also supports a good range of sockets, including Intel’s LGA1700 and AMD’s AM4, but is slightly less comprehensive. The Peerless Assassin's all-metal fasteners and SS2 buckle system further simplify its installation process. If you plan on building a system with diverse CPU options, the Peerless Assassin may provide a more versatile solution.
Brand Reputation
Thermalright has a strong reputation in the CPU cooling market, with over 20 years of experience in developing high-quality cooling solutions. Both the Peerless Assassin and AXP120-X67 are products of this established brand, ensuring reliability and performance. The Peerless Assassin has garnered attention for its effective cooling capabilities, while the AXP120-X67 is recognized for its compact design and aesthetic appeal. When choosing between these two, consider which features matter more to you—raw performance versus form factor.
Value for Money
In terms of pricing, the Peerless Assassin is available for C$54.90, while the AXP120-X67 is a more budget-friendly option priced at C$38.79. The difference of C$16.11 reflects the additional cooling performance and features of the Peerless Assassin. If you are on a tight budget or have a less demanding setup, the AXP120-X67 offers excellent value without compromising too much on cooling efficiency. Conversely, if maximum cooling performance and compatibility are your top priorities, the extra investment in the Peerless Assassin may be justified.
Which should you buy?
Ultimately, the decision between the Thermalright Peerless Assassin 140 Black and the Thermalright AXP120-X67 Black ARGB comes down to your specific needs. If you require a cooler that excels in performance and offers extensive compatibility, the Peerless Assassin at C$54.90 is the superior choice. However, if you are looking for a compact, aesthetically pleasing option that is budget-friendly, the AXP120-X67 at C$38.79 is a commendable alternative. Evaluate your build’s requirements, available space, and budget to determine which cooler best suits your needs.
