Overview of the Thermalright AXP90 X36 Black and Peerless Assassin 140 Black
The Thermalright AXP90 X36 Black is a low-profile CPU air cooler priced at C$26.90, while the Thermalright Peerless Assassin 140 Black offers a more robust cooling solution at C$54.90. The price difference of C$28.00 highlights the variance in performance and design between these two models. Each cooler is designed to address different requirements in CPU cooling, making them suitable for users with distinct needs.
Design and Build Quality
The Thermalright AXP90 X36 Black features a compact low-profile design, making it ideal for smaller builds where space is at a premium. In contrast, the Thermalright Peerless Assassin 140 Black boasts a twin-tower body with a height of 158mm, allowing for superior cooling potential. The larger structure of the Peerless Assassin enables it to accommodate high-performance components, while the AXP90 X36 is tailored for space-constrained setups. Both coolers are built with quality materials, but the construction of the Peerless Assassin may appeal more to users seeking optimal airflow and heat dissipation.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 140 Black excels with its dual fans and advanced heat dissipation technology. The cooler employs pure copper heat pipes that efficiently transfer heat from the CPU to the large area aluminium fins, aided by two high-performance fans that can operate at 1500 RPM. This combination ensures effective cooling for demanding applications. The AXP90 X36, while efficient for its size, may not match the cooling capacity of the Peerless Assassin, particularly in high-load scenarios.
Noise Levels
Noise levels are a crucial factor for many users, and the Thermalright Peerless Assassin 140 Black operates quietly at a noise value of ≤25.6 dB(A). This means that while providing powerful airflow, it maintains a relatively low noise output, making it suitable for quiet environments. The AXP90 X36's noise levels are not specified, but low-profile coolers typically aim for quieter operation. However, the Peerless Assassin’s dual fans provide a balance of performance and sound, making it a more versatile choice for various computing environments.
Compatibility and Installation
The Thermalright Peerless Assassin 140 Black is compatible with a wide range of CPU sockets, including Intel LGA1200 and AMD AM4, which makes it a versatile option for diverse setups. It comes with a comprehensive mounting kit that simplifies installation. On the other hand, the AXP90 X36, while also compatible with various sockets, is primarily designed for systems with limited space. Users should consider their specific motherboard and case dimensions when choosing between these two coolers to ensure compatibility.
Pricing and Value for Money
The pricing clearly indicates that the Thermalright AXP90 X36 Black is a more budget-friendly option at C$26.90, while the Peerless Assassin 140 Black is priced at C$54.90. The price difference reflects the cooling capabilities and design features of each cooler. For users seeking basic cooling solutions for less demanding tasks, the AXP90 X36 provides excellent value. However, for those who require superior cooling performance and are willing to invest more, the Peerless Assassin offers a compelling value proposition with its advanced features and effective cooling design.
User Experience and Feedback
User feedback for both coolers highlights their effectiveness in cooling, with many praising the Peerless Assassin 140 Black for its robust performance under load. Users appreciate the dual fans and the efficient thermal management system, which contributes to overall system stability. The AXP90 X36 is often commended for its space-saving design, making it a favourite among users with compact builds. However, some users might find it lacking in performance compared to larger coolers like the Peerless Assassin, especially during intensive tasks.
Which should you buy?
Choosing between the Thermalright AXP90 X36 Black and the Peerless Assassin 140 Black ultimately depends on your specific needs and setup. If you are working with a compact case and require a cost-effective solution, the AXP90 X36 is a solid choice at C$26.90.
