Dimension comparison
Brand Overview
Both the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright AXP120-X67 Low Profile CPU Air Cooler come from the reputable Taiwanese brand Thermalright, which has over 20 years of experience in developing computer accessories. This brand is known for its quality and innovation in the cooling market, making both products reliable choices for gamers and PC builders. The Assassin X 120 SE ARGB is priced at C$24.29, while the AXP120-X67 comes at a higher price of C$36.90, reflecting its unique features and design.
Design and Dimensions
The design and dimensions of these coolers cater to different needs. The Assassin X 120 SE measures 125mm in length, 71mm in width, and 148mm in height, making it a suitable option for medium-sized cases. In contrast, the AXP120-X67 is more compact, measuring 123.5mm in length, 120mm in width, and only 67mm in height, which allows for better compatibility in tighter spaces. This low-profile design makes the AXP120-X67 ideal for small form factor builds, while the larger Assassin X 120 SE provides a more robust cooling solution for standard builds.
Cooling Performance
Cooling performance is a crucial factor when choosing a CPU cooler, and here the two products differ significantly. The Assassin X 120 SE features four 6mm heat pipes and has a thermal design power (TDP) rating of 125 to 225 watts, making it suitable for higher-performance CPUs. It boasts a maximum airflow of 66.17 CFM and operates at a noise level of 25.6 dB(A). On the other hand, the AXP120-X67 uses six 6mm heat pipes and offers a maximum airflow of 59 CFM, with a slightly higher noise level of 26.1 dB(A). While both coolers effectively manage CPU temperatures, the Assassin X 120 SE has an edge in airflow and TDP capabilities.
Fan Specifications
The fan specifications reveal notable differences between the two models. The Assassin X 120 SE is equipped with a standard 120mm PWM fan that spins at a maximum speed of 1550 RPM. This fan is designed to deliver efficient cooling while maintaining a relatively low noise level. Conversely, the AXP120-X67 features a thinner 120mm PWM fan that can reach speeds of 1800 RPM, albeit at a slightly higher noise level. The increased RPM in the AXP120-X67 could offer better cooling under load, but it may come at the cost of increased noise, making the Assassin X 120 SE a quieter option for users valuing silence.
Installation and Compatibility
Installation and compatibility are essential considerations for any CPU cooler. The Assassin X 120 SE supports a wide range of Intel sockets, including 115X, 1200, and 1700, and AMD's AM4 socket. It comes with metal fasteners that ensure a secure installation. The AXP120-X67 also supports multiple Intel sockets, including 1700, 1150, and 1151, as well as AM4, making both coolers versatile options. However, the AXP120-X67's low-profile design may provide a more straightforward installation in compact cases where space is limited.
Material and Build Quality
Both coolers are constructed with high-quality materials, ensuring durability and performance. The Assassin X 120 SE uses an aluminum heat sink with a robust design, while the AXP120-X67 features aluminum fins on a copper base. The presence of copper in the AXP120-X67 may enhance thermal conductivity, leading to improved cooling performance. Each cooler employs advanced manufacturing techniques, including AGHP (Advanced Gravity Heat Pipe) technology, which helps mitigate the effects of orientation on cooling efficiency, ensuring consistent performance regardless of the installation position.
Noise Levels
Noise levels are an important factor for users who prefer a quiet computing environment. The Assassin X 120 SE operates at a maximum noise level of 25.6 dB(A), making it a quieter choice compared to the AXP120-X67, which has a maximum noise level of 26.1 dB(A). While the difference is marginal, the Assassin X 120 SE may be more appealing to users who are sensitive to noise and prefer a quieter cooling solution during operation.
Which should you buy?
Deciding between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright AXP120-X67 Low Profile CPU Air Cooler ultimately depends on your specific needs and preferences. If you require a cooler with higher airflow, better TDP capacity, and quieter operation, the Assassin X 120 SE at C$24.29 is the superior choice. However, if you are working with a compact build and need a low-profile option, the AXP120-X67 priced at C$36.90 offers excellent performance in a smaller form factor. Assessing your case size, noise tolerance, and cooling requirements will guide you in making the best decision for your setup.
