The AXP90 X36 is priced at C$26.90, while the Peerless Assassin 120 SE costs C$46.79. This reflects a significant difference of C$19.89, making the AXP90 X36 a more budget-friendly option for those looking for a low-profile cooling solution. The higher price of the Peerless Assassin can be attributed to its more advanced cooling features and larger design.
Cooling Performance
The Thermalright Peerless Assassin 120 SE is designed for superior cooling performance compared to the AXP90 X36. The Peerless Assassin features a dual tower and dual fan setup that enhances heat dissipation, making it a powerful choice for overclocked CPUs or high-performance builds. It achieves an air volume of 66.17 CFM, which is crucial for effective cooling. In contrast, the AXP90 X36, while low-profile, does not provide any specific cooling performance metrics, indicating it may not match the aggressive cooling capabilities of its competitor.
Design and Size
In terms of design, the Thermalright Peerless Assassin 120 SE stands out with its dimensions of 125 mm (L) x 135 mm (W) x 155 mm (H). This size allows for a more robust cooling solution while still being compatible with a variety of cases. The AXP90 X36, being a low-profile cooler, is optimised for smaller builds, but its lack of specified dimensions makes it challenging to assess its comparative size directly. Users with limited space may prefer the AXP90 X36, while those with larger cases will benefit from the more extensive capabilities of the Peerless Assassin.
Fan Technology
Fan technology plays a crucial role in CPU cooling, and here the Peerless Assassin 120 SE has a clear advantage. It features two TL-C12C Reverse Fans operating at a speed of 1550 RPM, delivering substantial airflow while maintaining a noise level of ≤25.6 dB(A). This combination of airflow and quiet operation makes it suitable for performance enthusiasts who value a peaceful computing environment. The AXP90 X36 lacks specific details on its fan technology, which may leave potential buyers wondering about its efficiency and noise levels.
Compatibility
Compatibility is a vital consideration when selecting a CPU cooler, and the Peerless Assassin 120 SE excels in this area. It supports a wide range of CPU sockets, including Intel's LGA1150, LGA1151, LGA1200, LGA1700, and AMD's AM4 and AM5. This ensures that it can be used with many modern builds. The AXP90 X36 does not specify its compatibility details, which could limit its appeal to users who want assurance that their cooler will work with their specific CPU and motherboard.
Installation Process
The installation process can significantly impact user experience, and the Peerless Assassin 120 SE offers an advantage here as well. It comes equipped with metal fasteners for both Intel and AMD platforms, simplifying the installation process. The AXP90 X36 does not provide any information regarding its installation features, leaving potential buyers without a clear understanding of how easy or challenging it would be to set up.
Market Positioning
In the competitive landscape of CPU coolers, the Thermalright AXP90 X36 is positioned as an entry-level option for users seeking a compact solution. Its lower price point of C$26.90 makes it accessible to budget-conscious consumers. On the other hand, the Thermalright Peerless Assassin 120 SE, with its advanced cooling features and higher price of C$46.79, targets enthusiasts who demand superior performance and are willing to invest more for better results. This clear market positioning helps buyers choose based on their specific needs and budget.
Which should you buy?
Ultimately, the choice between the Thermalright AXP90 X36 and the Thermalright Peerless Assassin 120 SE depends on your individual needs. If you're looking for a cost-effective, low-profile cooler that fits into smaller builds, the AXP90 X36 at C$26.90 may be your best bet. However, if you require superior cooling performance, compatibility across various CPU sockets, and enhanced installation features, the Peerless Assassin 120 SE, though pricier at C$46.79, represents a more powerful and versatile option. Your decision should be guided by your specific use case, budget, and performance expectations.
