Thermalright AXP90 X47 Full Low Profile CPU Cooler, vs Thermalright Peerless Assassin 120 Black CPU Air

Price Comparison

When considering price, the Thermalright AXP90 X47 Full Low Profile CPU Cooler is priced at $33.99, making it about 17% cheaper than the Thermalright Peerless Assassin 120 Black CPU Air Cooler, which retails for $38.90. This price difference may be significant for budget-conscious consumers looking for effective cooling solutions. While the AXP90 X47 offers a lower price point, the additional features and performance of the Peerless Assassin may justify its higher cost for some users.

Design and Dimensions

The Thermalright AXP90 X47 boasts an ultra-compact low-profile design with a total height of 47mm, making it ideal for small computer cases. In contrast, the Thermalright Peerless Assassin 120 Black has larger dimensions, measuring 125mm x 135mm x 157mm, which may limit its compatibility with compact builds. The low-profile AXP90 X47 is particularly advantageous for users with space constraints, while the larger design of the Peerless Assassin allows for more robust heat dissipation capabilities.

Cooling Performance

In terms of cooling performance, the Thermalright Peerless Assassin 120 Black is equipped with six heat pipes and two PWM fans, providing superior heat transfer and airflow of 66.17 CFM at a noise level of 25.6 dB(A). The AXP90 X47, while smaller, features four heat pipes and a single 92mm fan with airflow of 42.58 CFM and a noise level of 22.4 dB(A). Although the AXP90 X47 is quieter, the Peerless Assassin's dual fans and higher airflow may offer better cooling for high-performance CPUs.

Material and Build Quality

The Thermalright AXP90 X47 utilizes a pure copper base for excellent heat conductivity, complemented by a plating anti-oxidation protective layer to prevent corrosion. On the other hand, the Peerless Assassin 120 Black features an aluminum heatsink cover with a full electroplating reflow welding process, enhancing its heat dissipation area to 9600 cm². While both products use high-quality materials, the choice between copper and aluminum may depend on user preference regarding heat management and aesthetics.

Installation and Compatibility

Both coolers are compatible with a range of Intel and AMD sockets, including LGA 1150/1151/1155/1156/1200/1700 for Intel and AM4/AM5 for AMD. The AXP90 X47 is particularly suited for smaller builds, making installation straightforward in tighter spaces. In contrast, the Peerless Assassin 120 Black, with its larger footprint, may require more consideration during installation, but it also includes metal fasteners for improved mounting stability, which can appeal to users looking for reliability.

Noise Levels

When it comes to noise levels, the Thermalright AXP90 X47 operates at 22.4 dB(A), making it a quieter option compared to the Peerless Assassin 120 Black, which can reach noise levels of up to 25.6 dB(A). For users who prioritize a silent computing environment, the AXP90 X47 may be the better choice. However, the difference in noise levels might be negligible for users who are more focused on performance, as the cooling efficiency of the Peerless Assassin could outweigh its slightly higher noise output.

User Experience and Reviews

While specific sales ranks and bestseller statuses are not provided for either product, the Thermalright brand is generally well-regarded among PC enthusiasts for its reliable cooling solutions. Users have noted the AXP90 X47's excellent performance in compact systems and its ease of installation. Conversely, the Peerless Assassin 120 Black has received praise for its superior cooling capacity and dual-fan setup, which is beneficial for overclocking scenarios. User experiences may vary based on individual system configurations and cooling needs.

Which should you buy?

Ultimately, the decision between the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 Black CPU Air Cooler depends on your specific needs and constraints. If you're working with a compact build and looking for a budget-friendly option, the AXP90 X47 is a great choice at $33.99. However, if you prioritize maximum cooling performance and are willing to invest a bit more at $38.90, the Peerless Assassin 120 Black offers advanced features and efficiency that may be worth the price difference. Consider your system requirements, space limitations, and cooling needs to make the best choice for your setup.
