Dimension comparison
Brand Overview
Both the Thermalright AXP120-X67 Low Profile CPU Air Cooler and the Thermalright Assassin King 120 SE ARGB CPU Air Cooler come from Thermalright, a reputable Taiwanese brand with over 20 years of experience in developing computer accessories. This brand is well-regarded in both domestic and international markets, particularly among gaming enthusiasts. Thermalright focuses on research and development of various products, including CPU air coolers, case fans, and thermal compounds, demonstrating a commitment to quality and innovation across its product lines.
Design and Dimensions
The Thermalright AXP120-X67 features a low-profile design with dimensions of 123.5mm in length, 120mm in width, and 67mm in height. This compact size is particularly beneficial for systems with limited space. In contrast, the Thermalright Assassin King 120 SE has a slightly larger footprint, measuring 120mm in length, 73mm in width, and 148mm in height. The increased height of the Assassin King makes it suitable for medium-sized computer cases, providing more cooling potential but requiring additional vertical space in the setup.
Cooling Performance
In terms of cooling efficiency, the AXP120-X67 boasts a maximum airflow of 59 CFM with a noise level of up to 26.1 dB(A). This model utilises a PWM fan that operates at a speed of 1800 RPM, making it effective for maintaining low temperatures under load. On the other hand, the Assassin King 120 SE surpasses it slightly with an airflow of 66.17 CFM and a lower noise level of 25.6 dB(A), achieved with a fan speed of 1550 RPM. This suggests that while both coolers are effective, the Assassin King may provide marginally better cooling performance while remaining quieter.
Heat Pipe Technology
Both coolers incorporate Advanced Gravity Heat Pipe (AGHP) technology to optimise thermal performance. The AXP120-X67 utilises six 6mm heat pipes, designed to manage the inverse gravity effect in various orientations, ensuring efficient heat transfer. Meanwhile, the Assassin King 120 SE employs five 6mm heat pipes with AGHP III technology, indicating a refined approach to heat dissipation. Both models are engineered to handle significant thermal loads, with the Assassin King rated for a thermal design power (TDP) of 125 to 235W, which enhances its suitability for high-performance CPUs.
Compatibility
Compatibility is essential for ensuring that a CPU cooler fits with various motherboards and processors. The AXP120-X67 supports a wide range of Intel sockets, including 1700, 1150, and 2066, as well as AMD's AM4 platform. Similarly, the Assassin King 120 SE is compatible with Intel sockets 115X and 1200, as well as AMD's AM4 and AM5. Both coolers come with the necessary metal fasteners to facilitate easy installation, catering to a diverse set of users with different system configurations.
Aesthetics and Features
The aesthetic appeal of a CPU cooler can be as important as its performance, especially for those who value the look of their build. The AXP120-X67 has a straightforward design focused on functionality, making it suitable for users who prefer a minimalistic appearance. In contrast, the Assassin King 120 SE is equipped with ARGB lighting, offering colourful lighting effects that can enhance the overall visual experience of a gaming setup. This feature makes the Assassin King more appealing for users looking to add a touch of flair to their builds.
Price and Value
When it comes to pricing, the Thermalright AXP120-X67 is priced at C$36.90, while the Assassin King 120 SE is significantly more affordable at C$24.59. The price difference of C$12.31 may influence buyers, particularly those on a budget.
