Pricing Comparison
When it comes to pricing, the ARCTIC Liquid Freezer III Pro 360 is significantly more expensive than the TR-Assassin X 120R SE V2. The ARCTIC cooler is priced at £67.49, while the TR model costs just £14.49. This represents a staggering difference of £53.00. The higher price of the ARCTIC cooler reflects its advanced technology and features, while the TR cooler offers a budget-friendly option for those looking to save money without compromising too much on performance.
Design and Build Quality
The design and build quality of the ARCTIC Liquid Freezer III Pro 360 stand out with its premium construction and integrated cable management. It features a native offset mounting system for both Intel and AMD CPUs, which enhances heat transfer efficiency. In contrast, the TR-Assassin X 120R SE V2, while solidly constructed with an aluminium and copper heatsink, has a more traditional design. Its compact dimensions of 120(L)x71(W)x148(H)mm allow it to fit in most ATX cases without obstructing RAM modules, making it user-friendly for those with space constraints.
Cooling Performance
Cooling performance is a critical aspect of any CPU cooler, and the ARCTIC Liquid Freezer III Pro 360 excels in this department. It utilises ARCTIC's P12 PRO fan technology, which offers powerful and quieter operation, especially at lower speeds. The fan's higher maximum speed enhances cooling under heavy loads, making it ideal for high-performance setups. Conversely, the TR-Assassin X 120R SE V2 provides a rated airflow of 66.17 CFM at 1550 RPM. Although it is effective, its performance may not match the advanced cooling capabilities of the ARCTIC model during intensive tasks.
Compatibility
Compatibility is essential for ensuring that a cooler fits your system. The ARCTIC Liquid Freezer III Pro 360 is optimised for Intel LGA1851 and LGA1700, as well as AMD setups, making it versatile. It also features an integrated VRM fan that helps cool voltage converters, further enhancing system stability. On the other hand, the TR-Assassin X 120R SE V2 supports a wide range of motherboard sockets, including Intel LGA1150 through LGA1700 and AMD AM4/AM5. However, users need to use their original motherboard's built-in backplate for AM4/AM5 installations, which may be a minor inconvenience.
Noise Levels
Noise levels can significantly impact user experience, particularly in quiet environments. The ARCTIC Liquid Freezer III Pro 360 is designed to operate quietly, especially at low speeds, thanks to its P12 PRO fan. While specific noise levels are not mentioned, the emphasis on quieter operation suggests a focus on maintaining a serene computing environment. In comparison, the TR-Assassin X 120R SE V2 has a rated noise level of ≤25.6 dB(A), which is relatively quiet for a CPU air cooler. However, it may not be as silent under load as its ARCTIC counterpart.
Installation Process
The installation process can vary greatly between different CPU coolers. The ARCTIC Liquid Freezer III Pro 360 features a user-friendly design with an optimised contact pressure distribution system, which aids in longer CPU life and better heat dissipation. Its installation may require more effort due to the complexity of AIO coolers. Conversely, the TR-Assassin X 120R SE V2 employs a straightforward SS2 installation system and metal pressure plate, which ensures a better contact with the CPU. This simplicity makes it an appealing choice for those who prefer an easier installation experience.
Aesthetics
Aesthetics can play a significant role in a build, especially for those who value visual appeal. The ARCTIC Liquid Freezer III Pro 360 boasts a sleek design, enhanced by the integrated cable management that reduces clutter. This can create a clean look in a case, appealing to gamers and PC enthusiasts alike. The TR-Assassin X 120R SE V2, while functional, features static RGB lighting but may not offer the same level of visual sophistication as the ARCTIC cooler. Its simpler design is more utilitarian, aimed at providing performance over style.
Which should you buy?
Choosing between the ARCTIC Liquid Freezer III Pro 360 and the TR-Assassin X 120R SE V2 ultimately depends on your specific needs and budget. If you are looking for superior cooling performance, advanced features, and a more robust design, the ARCTIC cooler justifies its higher price of £67.49. However, if you are seeking a budget-friendly option that still delivers reliable cooling and easy installation, the TR-Assassin X 120R SE V2 at £14.49 is an excellent choice. Consider your system requirements and budget before making a decision, as both coolers cater to different user preferences.
