Dimension comparison
Overview of Products
In the realm of CPU cooling solutions, both Thermal Grizzly Duronaut and TR-Assassin X 120R SE V2 stand out with their unique attributes, priced equally at £14.49. While the former is a high-performance thermal paste, the latter is an air cooler designed for effective heat dissipation. Each product serves a distinct purpose in a PC build, catering to different cooling needs.
Thermal Conductivity
The Thermal Grizzly Duronaut boasts superior thermal conductivity, essential for optimal cooling performance. Formulated with aluminium microparticles and zinc oxide nanoparticles, it ensures efficient heat transfer. This advanced composition allows the paste to maintain exceptional long-term stability, preventing hardening over time. In contrast, the TR-Assassin X 120R SE V2 focuses on airflow, featuring a fan rated at 66.17 CFM for maximum cooling efficiency. While both products aim to enhance cooling, the method by which they achieve this varies significantly.
Application and Installation
When it comes to application, the Thermal Grizzly Duronaut is designed for ease of use, coming with the TG Spatula Pro for precise application. This tool allows users to spread the thermal paste in a thin layer, maximising thermal efficiency. On the other hand, the TR-Assassin X 120R SE V2 employs an SS2 install system along with a metal pressure plate on the heatsink. This design ensures better contact with the CPU but may require more effort during installation compared to the straightforward application of thermal paste.
Compatibility
Compatibility is a crucial factor in choosing cooling solutions. The Thermal Grizzly Duronaut is electrically non-conductive, making it safe for use on all electronic components. This feature eliminates the risk of short circuits, a critical consideration for many users. The TR-Assassin X 120R SE V2 has thoughtful compatibility with various motherboards, supporting both Intel and AMD systems, including LGA1700 and AM5. However, users need to use the original motherboard's built-in backplate for AMD installations, which may not be included.
Performance Longevity
Performance longevity is a significant advantage of the Thermal Grizzly Duronaut, as it is engineered to maintain its performance over extended periods without hardening. This means that users can expect consistent cooling effectiveness throughout the lifespan of the thermal paste. The TR-Assassin X 120R SE V2, while offering high airflow and low noise levels, may not have the same longevity in terms of thermal paste replacement, as air coolers can be affected by dust accumulation and fan wear over time.
Noise Levels
Noise levels play a vital role in user experience, especially for those who prefer quieter systems. The TR-Assassin X 120R SE V2 operates at a rated noise level of up to 25.6 dB(A), making it a relatively quiet option for an air cooler. In contrast, the Thermal Grizzly Duronaut, being a thermal paste, operates silently, as it does not have moving parts. This feature makes Duronaut an excellent choice for users prioritising noise-free operation in their builds.
Material Composition
The material composition of each product highlights their different cooling approaches. The Thermal Grizzly Duronaut uses advanced materials like aluminium and zinc oxide nanoparticles to achieve its excellent thermal conductivity. This formulation contributes to its exceptional long-term stability and performance. In contrast, the TR-Assassin X 120R SE V2 is constructed with a combination of aluminium and copper for the heatsink, optimising heat dissipation through effective thermal transfer. Both materials are well-suited for their respective purposes but serve different aspects of CPU cooling.
Price Point
Both the Thermal Grizzly Duronaut and TR-Assassin X 120R SE V2 are priced at £14.49, making them accessible options for users looking to enhance their cooling solutions. While the cost is identical, the value each product provides depends on the specific cooling requirements of the user. For those who need effective thermal paste for CPU application, Duronaut is the clear choice. Conversely, users seeking an air cooler with RGB lighting and high airflow performance may find the TR-Assassin X 120R SE V2 to be more beneficial.
Which should you buy?
Ultimately, the decision between Thermal Grizzly Duronaut and TR-Assassin X 120R SE V2 hinges on your specific cooling needs. If you require a long-lasting thermal paste that excels in heat transfer and application ease, Thermal Grizzly Duronaut is the ideal choice. However, if you prefer a robust air cooler with high airflow and compatibility across various motherboards, the TR-Assassin X 120R SE V2 would be suitable. Consider your system's requirements and cooling strategy to make the best choice for your build.
