Overview of Thermalright AXP-120-X67 Black ARGB and Thermalright Peerless Assassin 120 SE

The Thermalright AXP-120-X67 Black ARGB is priced at $32.59, making it about 35% cheaper than the Thermalright Peerless Assassin 120 SE, which retails for $49.99. Both products are designed for performance and compatibility, but they cater to different needs within the CPU cooling market. The AXP-120-X67 is a low-profile option, ideal for compact builds, whereas the Peerless Assassin offers a more robust cooling solution with dual fans and a larger footprint.

Design and Build Quality

The design of the AXP-120-X67 focuses on a compact form factor with a total height of 67mm, making it suitable for smaller cases. It features an aluminum fin on a copper base and is equipped with a PWM fan that operates at a maximum speed of 1800 RPM. In contrast, the Peerless Assassin stands taller at 155mm and utilizes a dual tower cooling design, which enhances its thermal performance. It also employs two PWM fans, each capable of spinning at 1550 RPM, providing effective airflow and cooling efficiency. The choice between these designs comes down to your specific case dimensions and cooling needs.

Cooling Performance

In terms of cooling performance, the Peerless Assassin 120 SE is designed to outperform the AXP-120-X67 due to its dual-fan setup and larger heat sink area. The AXP-120-X67 utilizes six heat pipes with a focus on AGHP technology to ensure efficient heat dissipation, but it may fall short in extreme overclocking scenarios compared to the Peerless Assassin. The dual fans of the Peerless Assassin can deliver a maximum airflow of 66.17 CFM at a noise level of 25.6 dB(A), while the AXP-120-X67 achieves a maximum airflow of 59 CFM at 26.1 dB(A). If high-performance cooling is your priority, the Peerless Assassin is the better choice.

Compatibility

Both coolers offer extensive compatibility with various Intel and AMD sockets, making them versatile options for different builds. The AXP-120-X67 supports Intel sockets LGA 1700, 1150, 1151, 1155, 1156, 1200, 2011, and 2066, as well as AMD's AM4 platform. The Peerless Assassin also supports a wide range of sockets, including LGA 1700, 1150, 1151, 1200, 1851 for Intel and AM4 and AM5 for AMD. This compatibility ensures that both products can cater to a large portion of the market, appealing to users across various platforms.

Noise Levels

In terms of noise levels, both coolers strive for quiet operation, but they perform slightly differently under load. The AXP-120-X67 has a maximum noise level of 26.1 dB(A), while the Peerless Assassin operates at a slightly quieter 25.6 dB(A). This minimal difference may not be significant for most users, but if a silent build is a priority for you, the Peerless Assassin has a slight edge. Both coolers are engineered to provide effective cooling without becoming a distraction during operation.

Installation Process

When it comes to installation, both coolers are equipped with metal fasteners for easy mounting on Intel and AMD platforms. However, the AXP-120-X67's low-profile design may offer a simpler installation experience in tighter spaces due to its compact size. The Peerless Assassin, while still user-friendly, requires careful consideration of case size, as its double tower design demands more room. If ease of installation is a key factor for you, the AXP-120-X67 might be the more convenient option.

Brand Reputation

Both coolers come from Thermalright, a reputable brand with over 20 years of experience in the cooling industry. Known for their reliable and quality products, Thermalright has established a strong presence in the CPU cooler market. This brand reputation adds a level of trustworthiness to both the AXP-120-X67 and the Peerless Assassin, ensuring that customers can expect solid performance and durability from either choice.

Which should you buy?

Ultimately, the decision between the Thermalright AXP-120-X67 Black ARGB and the Thermalright Peerless Assassin 120 SE boils down to your specific needs and build considerations. If you require a low-profile cooler for a compact build and want to save around $17.40, the AXP-120-X67 is an excellent choice. However, if you are looking for superior cooling performance and are willing to invest an additional $17.40 for a dual-fan setup, the Peerless Assassin offers enhanced thermal capabilities. Consider your case size, cooling requirements, and budget to make the most informed decision.
