Overview of Products
The Corsair XTM70 Extreme Performance Thermal Paste is designed to enhance cooling efficiency, while the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler provides a comprehensive solution for CPU cooling. The Corsair thermal paste is priced at £14.99, making it an affordable option for those looking to improve heat transfer in their systems. In contrast, the Thermalright cooler is available for £28.79, offering a more robust cooling solution for high-performance CPUs.
Cooling Efficiency
The primary function of both products is to manage heat effectively, but they operate in fundamentally different ways. The Corsair XTM70 thermal paste is designed to transfer heat between the processor and its cold plate, making it suitable for high-performance processors with a thermal design power (TDP) of up to 250W and higher. On the other hand, the Thermalright Peerless Assassin 120 SE employs dual PWM fans and advanced heat pipe technology to maintain optimal temperatures, boasting a maximum airflow of 66.17 CFM and a noise level of 25.6 dB(A). This suggests that while the thermal paste excels in thermal conductivity, the air cooler provides a more active cooling solution.
Application and Installation
When it comes to application and installation, the Corsair XTM70 thermal paste offers a user-friendly experience. It features low viscosity, allowing for smooth application with the included applicator kit. The product also comes with three cleaning wipes to remove old paste from the processor and cold plate, ensuring a clean surface for optimal performance. In contrast, the Thermalright cooler supports various CPU sockets, including Intel and AMD platforms, and comes with the necessary mounting hardware for easy installation. This means that while the thermal paste offers straightforward application, the air cooler provides versatility across different systems.
Design and Aesthetics
In terms of design, the Corsair XTM70 thermal paste is straightforward and functional, focusing on performance rather than aesthetics. Conversely, the Thermalright Peerless Assassin 120 SE features colourful ARGB lighting effects, adding a visual appeal to your build. With dimensions of 125mm x 135mm x 155mm, it stands out as a double tower cooler that not only performs well but also enhances the overall look of a gaming or workstation setup. This difference means that users looking for aesthetic enhancements may prefer the Thermalright option.
Brand Reputation
Corsair is a well-established brand in the gaming and hardware industry, known for its quality components and accessories. The Corsair XTM70 thermal paste builds on this reputation by promising superior thermal conductivity. Thermalright, on the other hand, has over 20 years of experience in developing computer accessories, making it a respected name in the CPU cooling market. Both brands offer products that are trusted by consumers, but their focus areas differ, with Corsair leaning towards performance and Thermalright providing a balance of performance and aesthetics.
Target Audience
The target audience for these two products differs significantly. The Corsair XTM70 thermal paste is ideal for gamers or professionals seeking to optimise their existing cooling solutions without investing in a full cooler. At £14.99, it provides a cost-effective way to enhance CPU performance. In contrast, the Thermalright Peerless Assassin 120 SE is aimed at users looking for an all-in-one cooling solution that combines performance with aesthetic features. Its higher price of £28.79 reflects its multifunctional capabilities, appealing to those who prioritise both form and function in their builds.
Performance Under Load
When subjected to high-performance tasks, the effectiveness of each product becomes apparent. The Corsair XTM70 thermal paste is specifically designed to maintain stability in high-temperature environments, making it suitable for processors with a TDP of up to 250W. The Thermalright Peerless Assassin 120 SE, with its dual fans and advanced heat pipe configuration, is engineered to dissipate heat efficiently, ensuring that CPUs remain cool under load. This dual approach to heat management indicates that while the thermal paste provides essential thermal transfer, the air cooler offers a comprehensive solution for sustained performance during demanding applications.
Which should you buy?
Deciding between the Corsair XTM70 Extreme Performance Thermal Paste and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler largely depends on your specific needs. If you are looking for a cost-effective way to enhance your existing cooling setup and you already have a cooler in place, the Corsair thermal paste is an excellent choice at £14.99. However, if you require a full cooling solution that not only provides effective heat dissipation but also adds visual flair to your system, the Thermalright cooler at £28.79 is worth the investment. Ultimately, both products excel in their respective categories, catering to different segments of the market.
