Price Comparison
The MSI MAG CORELIQUID A13 is priced at £53.99, while the Thermalright Peerless Assassin 120 SE comes in significantly cheaper at £28.79. This price difference of £25.20 highlights a substantial gap between the two products, which may influence budget-conscious consumers. The MSI cooler's higher price reflects its advanced features and technology, such as the enhanced cooling capabilities and ARGB aesthetics. Conversely, the Thermalright model offers a more economical solution while still delivering essential cooling performance, making it an attractive option for users who prioritise cost over premium features.
Cooling Performance
In terms of cooling efficiency, the MSI MAG CORELIQUID A13 features an enlarged copper cold plate and more internal micro-channels, which enhance heat dissipation. It operates with a high-performance pump that can reach speeds up to 3800 RPM, providing effective cooling even under heavy loads. On the other hand, the Thermalright Peerless Assassin utilises six heat pipes with AGHP technology to tackle the inverse gravity effect, ensuring consistent performance regardless of orientation. Although both coolers are designed to manage CPU temperatures effectively, the MSI model's design suggests it is better suited for high-performance scenarios, making it a superior choice for overclocking enthusiasts.
Noise Levels
When considering noise levels, the MSI MAG CORELIQUID A13 operates at a moderate noise level of 31.1 dBA, which is acceptable for most users, especially considering its performance capabilities. In contrast, the Thermalright Peerless Assassin is quieter, with a maximum noise level of only 25.6 dBA. This lower noise output may appeal to users who prioritise a silent computing experience, particularly in environments where noise is a significant concern. Therefore, while the MSI cooler may deliver better performance, the Thermalright model offers a quieter operation, making it a strong contender for users sensitive to noise.
Aesthetic Appeal
The MSI MAG CORELIQUID A13 features translucent fan blades that accentuate its ARGB illumination, creating an exquisite visual experience that is further enhanced by its frosted exterior finish. The design is sleek, with a semi-transparent MSI logo that harmonises with the overall aesthetic. In contrast, the Thermalright Peerless Assassin also offers colourful ARGB light effects, but it does not have the same level of visual refinement as the MSI cooler. While both coolers include RGB lighting, the MSI cooler's design is arguably more polished and sophisticated, potentially appealing to gamers and PC builders who value aesthetics alongside performance.
Installation Process
The MSI MAG CORELIQUID A13 comes with pre-installed fans, which simplifies the installation process and enhances the assembly experience for users. This feature can save significant time during setup, especially for those who may not be as experienced with building PCs. Conversely, the Thermalright Peerless Assassin is designed to be compatible with a wide range of CPU sockets, including Intel’s 115X/1200/1700 and AMD’s AM4/AM5, and includes the necessary mounting plates for installation. Although both products aim to ease the installation process, the MSI cooler’s pre-installed fans provide a notable advantage for those looking for a straightforward setup.
Brand Reputation
MSI has established itself as a prominent player in the gaming and PC hardware market, known for delivering high-quality products with innovative technology. Their experience in the industry, combined with a reputation for performance, makes the MSI MAG CORELIQUID A13 a reliable choice for consumers. On the other hand, Thermalright, with over 20 years of development, has carved out a niche in the CPU cooling market, offering effective and competitive alternatives. While both brands have their strengths, MSI's strong branding in gaming may resonate more with enthusiasts looking for cutting-edge products, while Thermalright appeals to users seeking solid performance at a lower price point.
User Experience
The user experience with the MSI MAG CORELIQUID A13 is enhanced by its balance of performance and quiet operation, thanks to high-quality ceramic bearings in the pump. This design not only contributes to effective cooling but also ensures longevity. The Thermalright Peerless Assassin is designed with ultra-silent airflow fans, aiming for extreme CPU cooling performance while maintaining a low noise level. Both products focus on user satisfaction; however, the MSI cooler's emphasis on performance and aesthetic appeal may attract users looking for a comprehensive solution, while the Thermalright's affordability and effective cooling make it a practical choice for everyday use.
Which should you buy?
Choosing between the MSI MAG CORELIQUID A13 and the Thermalright Peerless Assassin 120 SE ultimately depends on your specific needs and budget. If you are willing to invest more for superior cooling performance, advanced technology, and striking aesthetics, the MSI cooler is the clear winner. However, if you are looking for a budget-friendly option that still provides effective cooling and operates quietly, the Thermalright cooler is a commendable choice. Each product has its strengths, so consider your priorities—performance, noise levels, design, and price—before making a decision.
