Overview of the Products
When it comes to CPU coolers, the Thermalright AXP90 X47 Black Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler are both excellent choices, each catering to different needs. The AXP90 X47 is priced at $22.39, making it about 43% cheaper than the Peerless Assassin, which comes in at $38.99. This price difference reflects their distinct designs and target applications. The AXP90 X47 is a compact, low-profile cooler ideal for smaller builds, while the Peerless Assassin is a dual tower cooler designed for more demanding setups.
Design and Build Quality
The design of the AXP90 X47 is notable for its low-profile nature, standing at just 47mm tall. This compact size is perfect for ITX builds where space is limited. It features an all-metal platform and a back plate fastener, enhancing its durability. In contrast, the Peerless Assassin boasts a dual tower design with six heat pipes, significantly improving heat dissipation, which is crucial for high-load scenarios like gaming or multitasking. The larger dimensions of the Peerless Assassin allow for better airflow but may not fit in smaller cases.
Cooling Performance
Cooling performance is where the Peerless Assassin truly shines. Its dual 120mm PWM fans can reach speeds of up to 1850 RPM, providing robust airflow and efficient cooling for high-performance components. The six heat pipes work in tandem with the fans to ensure stable thermal performance, making it suitable for intensive tasks. On the other hand, the AXP90 X47, with its single 92mm fan, operates at a quieter noise level of 22.4 dBA but may not dissipate heat as effectively under heavy loads. This makes the AXP90 X47 more suitable for less demanding applications.
Compatibility
Compatibility is a critical factor in choosing a CPU cooler, and both coolers offer support for a range of AMD and Intel sockets. The AXP90 X47 is compatible with AMD AM4 and AM5, as well as Intel 1150, 1151, 1155, 1851, and 1200 sockets. This broad compatibility makes it a versatile option for various builds. The Peerless Assassin also supports AMD AM4 and AM5, along with Intel LGA1851 and 1700, making it a solid choice for mainstream desktop builds. Both coolers cater to a wide audience, but the AXP90 X47 may have an edge in compact systems.
Noise Levels
Noise levels can significantly impact the user experience, especially in quieter environments. The AXP90 X47 operates at a maximum noise level of 22.4 dBA, ensuring that it remains unobtrusive during operation. In contrast, the Peerless Assassin, with its larger fans, produces a noise level of up to 29.5 dBA. While this is still manageable, it may be noticeable in quieter settings. Therefore, if noise is a priority, the AXP90 X47 is the better choice, especially for users who prefer a silent computing experience.
Price Consideration
Price is a substantial factor when choosing between the AXP90 X47 and the Peerless Assassin. Retailing at $22.39, the AXP90 X47 is considerably cheaper than the Peerless Assassin, which is priced at $38.99. This difference of $16.60 is about 43% less, making the AXP90 X47 an attractive option for budget-conscious consumers or those building entry-level systems. However, the additional investment in the Peerless Assassin may be justified for users seeking superior cooling performance and versatility in high-performance setups.
Target Audience
The target audience for these two coolers varies significantly. The AXP90 X47 is an excellent choice for users building compact systems or those who prioritize a low-profile cooler for space-constrained environments. Its affordable price point and adequate cooling performance make it suitable for basic gaming or office tasks. In contrast, the Peerless Assassin targets gamers and professionals who require top-tier cooling for demanding applications. Its advanced cooling features and larger design cater to high-performance desktop builds, making it a preferred option for serious enthusiasts.
Which should you buy?
Ultimately, the choice between the Thermalright AXP90 X47 Black Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler depends on your specific needs and budget. If you're looking for a compact, affordable solution for a small form factor build, the AXP90 X47 is an excellent choice at just $22.39. However, if you need superior cooling performance for high-load applications and are willing to invest more, the Peerless Assassin at $38.99 offers better airflow and thermal stability. Consider your build requirements and budget before making a decision.
