Dimension comparison
Brand Overview
Both the Thermalright Assassin X 90 SE V2 CPU Cooler and the Thermalright AXP120-X67 Black ARGB Low Profile CPU Air Cooler are products from the reputable Taiwanese brand Thermalright, which boasts over 20 years of experience in the cooling solutions market. While both coolers share the same brand heritage, their designs and applications cater to slightly different user needs. The Assassin X 90 SE V2 focuses on powerful cooling performance, while the AXP120-X67 is crafted for users seeking a low-profile solution suitable for compact builds.
Cooling Performance
The cooling performance of the Thermalright Assassin X 90 SE V2 is enhanced by its AGHP (Advanced Gravity Heat Pipe) technology, which utilises a 4x6mm heatpipe design to offer effective heat dissipation. This cooler features a maximum airflow of 32.77 CFM, which, when combined with its high-speed fan capable of running at 2200 RPM, ensures robust cooling capabilities. In contrast, the AXP120-X67 is designed with a focus on quieter operation, delivering airflow of up to 59 CFM with a maximum fan speed of 1800 RPM. While the AXP120-X67 offers higher airflow, the Assassin X 90 SE V2's RPM advantage may lead to superior cooling under high-performance situations.
Design and Dimensions
In terms of physical dimensions, the Thermalright Assassin X 90 SE V2 measures 94mm in length, 77mm in width, and 118mm in height, making it a compact yet potent cooler. On the other hand, the AXP120-X67 has larger dimensions, measuring 123.5mm in length, 120mm in width, and only 67mm in height. The low-profile design of the AXP120-X67 makes it particularly appealing for users with limited space in their cases, while the taller profile of the Assassin X 90 SE V2 may restrict its compatibility with some smaller chassis.
Noise Levels
When it comes to noise levels, the Thermalright Assassin X 90 SE V2 operates at a maximum of 23.85 dB(A), which is quite quiet, especially for users who are sensitive to sound. The AXP120-X67, while designed for quieter operations, has a slightly higher maximum noise level of 26.1 dB(A). This difference may be negligible for some users, but it could be a deciding factor for those who prioritise a silent computing environment.
Fan Technology
Both CPU coolers employ PWM (Pulse Width Modulation) fans, which allow for dynamic speed adjustments based on cooling demand. The Thermalright Assassin X 90 SE V2 utilises a 92mm fan, while the AXP120-X67 features a larger 120mm fan. The larger fan on the AXP120-X67 can potentially move more air at lower RPMs, contributing to quieter operation without sacrificing performance. Conversely, the smaller fan of the Assassin X 90 SE V2 runs at a higher RPM to achieve its cooling efficiency, which may lead to more noise but potentially better cooling under load.
Compatibility
Compatibility is crucial for CPU coolers, and both the Thermalright Assassin X 90 SE V2 and the AXP120-X67 are designed with broad support for various CPU sockets. The Assassin X 90 SE V2 is compatible with Intel sockets 1150, 1151, 1155, 1156, and 1200, as well as AMD’s AM4 and AM5. Meanwhile, the AXP120-X67 supports a wider range of Intel sockets, including 1700, 1150, 1151, 1155, 1156, 1200, 2011, and 2066, along with AMD’s AM4. Users with diverse setups may find the AXP120-X67 to be more accommodating due to its extensive compatibility list.
Price Comparison
The Thermalright Assassin X 90 SE V2 is priced at C$24.90, making it an affordable option for those seeking efficient cooling without breaking the bank. In contrast, the AXP120-X67 is priced higher at C$38.79. This price difference reflects the additional design features and performance capabilities offered by the AXP120-X67, particularly its low-profile design and higher airflow. While both coolers present good value within their respective price ranges, budget-conscious users may lean towards the more economical Assassin X 90 SE V2.
Which should you buy?
Choosing between the Thermalright Assassin X 90 SE V2 and the AXP120-X67 ultimately depends on your specific needs and preferences. If you require a more compact cooler with good performance and lower price, the Thermalright Assassin X 90 SE V2 is an excellent choice. However, if you're looking for a low-profile solution that offers higher airflow and a quieter operation, the AXP120-X67 is worth the investment. Both coolers carry the Thermalright legacy of quality, ensuring that whichever you pick, you’ll get a reliable cooling solution.
