Overview of the Products
In this comparison, we will explore two cooling solutions: the Corsair XTM70 Extreme Performance Thermal Paste and the TR-Assassin X 120R SE V2 CPU Air Cooler. Both products cater to the needs of high-performance computing systems, but they do so in very different ways. The Corsair XTM70 is a thermal paste designed to enhance heat transfer between components, while the TR-Assassin X 120R SE V2 is an air cooler that actively dissipates heat. Understanding their unique features will help you determine which product is better suited for your setup.
Cooling Efficiency
The Corsair XTM70 excels in thermal conductivity, making it ideal for high-performance processors with a thermal design power (TDP) of up to 250W and higher. Its low viscosity allows it to spread evenly across the surface, ensuring peak thermal transfer. In contrast, the TR-Assassin X 120R SE V2 features a heatsink made from aluminium and copper, which contributes to its ability to manage heat effectively. The cooler is designed with a high airflow performance fan that operates at a speed of 1550 RPM, delivering a maximum airflow of 66.17 CFM. While both products aim to maintain optimal temperatures, the Corsair XTM70 focuses on enhancing the connection between components, whereas the TR-Assassin X 120R SE V2 actively cools the CPU.
Application and Installation
When it comes to application, the Corsair XTM70 provides an applicator kit that simplifies the process of applying thermal paste. This is particularly important for users who may not have prior experience with thermal paste applications. Additionally, it includes three cleaning wipes to assist in removing old paste, ensuring a clean surface for optimal performance. On the other hand, the TR-Assassin X 120R SE V2 features an SS2 installation system and a metal pressure plate that ensures robust contact with the CPU. Its compact size, with dimensions of 120mm x 71mm x 148mm, allows it to fit in most ATX cases, making installation straightforward. Both products offer ease of use, but the Corsair XTM70 shines in its application process.
Compatibility
The Corsair XTM70 is versatile, compatible with both Intel and AMD CPUs, making it an excellent choice for a wide range of systems. In contrast, the TR-Assassin X 120R SE V2 supports various Intel and AMD sockets, including LGA1150 through LGA1700 for Intel and AM4 and AM5 for AMD. However, it requires the original motherboard's backplate for installation on AM4 and AM5, which may be a consideration for some users. While both products cater to different compatibility needs, the Corsair XTM70's broader compatibility may appeal to those with diverse setups.
Noise Levels
Noise levels are a critical consideration for many users, particularly in environments where silence is valued. The TR-Assassin X 120R SE V2 operates with a rated noise level of 25.6 dB(A), which is relatively quiet for a CPU cooler, especially given its performance capabilities. In contrast, the Corsair XTM70 does not produce noise in itself, as it is a thermal paste rather than an active cooling solution. Therefore, if noise is a primary concern, the choice between the two will depend on whether you prefer a passive solution like the Corsair XTM70 or an active cooler with a low noise output like the TR-Assassin X 120R SE V2.
Performance Under Load
When subjected to demanding tasks, the Corsair XTM70 thermal paste ensures that high-performance CPUs maintain optimal temperatures by efficiently transferring heat. It is particularly beneficial for users running intensive applications or overclocking their processors. The TR-Assassin X 120R SE V2, with its high airflow and low noise fan, also performs well under load, keeping the CPU cool even during strenuous activities. Both products are designed to prevent overheating, but the XTM70’s high thermal efficiency can provide a slight edge in extreme conditions.
Price and Value
The Corsair XTM70 is priced at £14.99, while the TR-Assassin X 120R SE V2 is slightly cheaper at £14.49. Although the price difference is minimal, it may influence budget-conscious consumers. The Corsair XTM70 offers multiple applications, which can enhance its value for users needing to reapply thermal paste frequently. Conversely, the TR-Assassin X 120R SE V2 delivers a complete cooling solution, which may justify its price for those seeking an all-in-one cooling solution. Overall, both products present good value within their respective categories.
Brand Reputation
Corsair and TR are both reputable brands in the cooling solutions market. Corsair is well-known for its high-performance components and accessories, particularly in the gaming and enthusiast communities. The Corsair XTM70 thermal paste benefits from this strong brand reputation, assuring users of its quality and effectiveness. TR, while perhaps less widely recognised, is known for producing competitively priced cooling solutions with solid performance. Both brands have their loyal customer bases, but Corsair’s established reputation may give it an edge for some consumers.
Which should you buy?
Choosing between the Corsair XTM70 Extreme Performance Thermal Paste and the TR-Assassin X 120R SE V2 CPU Air Cooler ultimately depends on your specific needs. If you're looking for a solution that enhances thermal conductivity and is easy to apply, the Corsair XTM70 is an excellent choice, especially for high-performance setups. However, if you prefer an active cooling solution that offers robust performance with relatively low noise, the TR-Assassin X 120R SE V2 is likely the better option. Each product has its strengths, so consider your requirements carefully before making a decision.
