Price Comparison

When comparing the ARCTIC MX-6 and the TR-Assassin X 120R SE V2 CPU Air Cooler, the most immediate difference is their price. The ARCTIC MX-6 is priced at £6.99, making it a budget-friendly option for those looking for a thermal paste solution. In contrast, the TR-Assassin X 120R SE V2 is significantly more expensive at £14.49. This price difference of £7.50 highlights the different markets these products cater to; the MX-6 is designed for users seeking effective thermal conductivity at a low cost, while the TR-Assassin X offers more features and performance enhancements for a higher investment.

Performance and Efficiency

The ARCTIC MX-6 boasts a 20% improvement in thermal performance compared to its predecessor, the MX-4, thanks to its lower thermal resistance. This makes it an excellent choice for those who need reliable thermal management for their CPUs or GPUs. On the other hand, the TR-Assassin X 120R SE V2 features a high airflow performance with a rated airflow of 66.17 CFM and a maximum fan speed of 1550 RPM. While the MX-6 focuses on thermal transfer, the TR-Assassin X provides cooling efficiency through its advanced heatsink design and fan capabilities. Therefore, the choice in this category largely depends on whether the user prioritises thermal paste or a full air cooling solution.

Build Quality and Material

The construction of both products reflects their intended use cases. The ARCTIC MX-6 is crafted to be electrically non-conductive and non-capacitive, reducing the risk of short circuits during application. Its composition is designed for versatility, making it suitable for various thermal applications. In contrast, the TR-Assassin X features a heatsink made from both aluminium and copper, providing the necessary durability and efficiency for a CPU cooler. The use of SS2 install system and metal pressure plate enhances its performance by ensuring better contact with the CPU. Thus, while the MX-6 excels in application safety, the TR-Assassin X offers a more robust physical structure.

Compatibility

Compatibility is another area where the two products differ significantly. The ARCTIC MX-6 is a universal thermal paste that can be applied to various components, including graphics cards and console processors, making it highly versatile. The TR-Assassin X, however, has specific motherboard compatibility, supporting Intel sockets from LGA1150 to LGA1700 and AMD’s AM4 and AM5. The requirement for the original motherboard's backplate during installation adds a layer of complexity. Users looking for an easy installation will find the MX-6 more accommodating, whereas the TR-Assassin X is better suited for those who have compatible hardware and are aiming for high-performance cooling.

Application Ease

In terms of application ease, the ARCTIC MX-6 is designed for a risk-free application process, enabling users to apply it without fear of causing electrical issues. Its consistency allows for a straightforward spread, making it user-friendly, especially for beginners. Conversely, the TR-Assassin X requires a more intricate installation process due to its heatsink design and need for specific mounting systems. While it may require more effort to install, once set up, it offers considerable cooling advantages for high-performance CPUs. Users who are comfortable with more complex installations may prefer the TR-Assassin X, while novices might be drawn to the simplicity of the MX-6.

Noise Levels

Noise levels are an important consideration for many PC builders. The TR-Assassin X operates at a rated noise level of 25.6 dB(A), which is relatively quiet for a cooling unit, especially considering its performance capabilities. In contrast, since the ARCTIC MX-6 is thermal paste, it doesn’t generate noise during operation. This gives the MX-6 a distinct advantage in noise-sensitive environments such as home theatres or quiet office spaces. However, for users who are focused on overall performance and are willing to tolerate some noise, the TR-Assassin X offers a good balance of cooling power and acceptable sound levels.

Brand Reputation and Experience

Both ARCTIC and TR have established reputations in the PC cooling market, but their focus differs. ARCTIC has over 20 years of experience concentrating on improving thermal performance and versatile application possibilities, which speaks to their commitment to quality and innovation in thermal solutions. TR, while newer in some aspects, provides a robust range of cooling products that cater to performance enthusiasts. The experience of ARCTIC in the thermal paste sector gives it a slight edge in terms of reliability and user trust for those specifically seeking thermal interface materials.

Which should you buy?

Choosing between the ARCTIC MX-6 and the TR-Assassin X 120R SE V2 ultimately depends on your specific needs and preferences. If you are looking for an affordable, reliable thermal paste with a focus on ease of application and versatility, the ARCTIC MX-6 is the clear winner at £6.99. However, if you need a high-performance air cooler with advanced features for a powerful CPU and are willing to invest a bit more at £14.49, the TR-Assassin X could be the better option. Each product has its strengths, so the decision should align with your cooling requirements and budget considerations.
