Brand Overview
Thermalright and Corsair are two reputable brands in the cooling solutions market, each with distinct heritage and focus. Thermalright boasts over 20 years of experience in developing computer accessories, whereas Corsair is well-known for its innovative gaming hardware and peripherals. The Thermalright Peerless Assassin 120 SE CPU Air Cooler is priced at £26.90, making it an affordable option for air cooling enthusiasts. In contrast, the Corsair NAUTILUS 360 RS LCD Liquid CPU Cooler is positioned at a higher price point of £99.98, reflecting its advanced liquid cooling technology and premium features.
Cooling Performance
The cooling performance of a CPU cooler is crucial for maintaining optimal temperatures during high workloads. The Thermalright Peerless Assassin 120 SE is designed with a dual tower cooling system and six heat pipes, which enhances its cooling capacity significantly. It features dual PWM fans that operate at a maximum speed of 1550 RPM, generating an airflow of 66.17 CFM while maintaining a noise level of ≤25.6 dB(A). This makes it a solid choice for users seeking effective air cooling. Conversely, the Corsair NAUTILUS 360 RS utilises a liquid cooling setup, which generally offers superior heat dissipation. Its efficient pump operates at a whisper-quiet level of just 20 dBA, ensuring that even under load, the cooler remains unobtrusive while providing effective cooling.
Design and Aesthetics
Design plays a significant role in many PC builds, and both coolers have unique aesthetics. The Thermalright Peerless Assassin 120 SE features a straightforward yet robust design with a traditional air cooler layout, suitable for a variety of setups. On the other hand, the Corsair NAUTILUS 360 RS stands out with its customisable LCD screen, allowing users to personalise their cooling display. This modern touch not only enhances the visual appeal of a gaming rig but also provides real-time information about CPU temperatures and performance, making it a more engaging option for users who value aesthetics alongside functionality.
Installation and Compatibility
Ease of installation is essential for both novice and experienced builders. The Thermalright Peerless Assassin 120 SE includes metal fasteners compatible with various Intel and AMD platforms, ensuring a straightforward installation process. It supports a range of sockets, including Intel’s LGA1700 and AMD's AM5, which enhances its versatility. In contrast, the Corsair NAUTILUS 360 RS also features a user-friendly installation process with pre-applied thermal paste on its convex cold plate, ensuring maximum contact with the CPU. This design feature simplifies the setup, making it faster and less prone to installation errors, a notable advantage for first-time builders.
Noise Levels
Noise levels are a critical consideration for users who prefer quiet operation. The Thermalright Peerless Assassin 120 SE operates at a maximum noise level of just 25.6 dB(A), which is relatively quiet for an air cooler, making it suitable for any environment. The dual fans help in achieving this low noise level while still providing robust cooling. In comparison, the Corsair NAUTILUS 360 RS excels with its even quieter operation, producing only 20 dBA due to its efficient pump and fan design. This lower noise level, combined with its outstanding cooling efficiency, positions it as an ideal choice for users who prioritise a silent setup.
Price Consideration
Price is often a deciding factor in purchasing decisions, and there is a significant difference between the two products. The Thermalright Peerless Assassin 120 SE is priced at £26.90, making it an economical choice for users on a budget or those looking for a reliable air cooler without breaking the bank. In contrast, the Corsair NAUTILUS 360 RS, at £99.98, represents a more substantial investment. This price reflects its advanced technology and additional features, such as the LCD screen and superior cooling performance. Potential buyers should weigh their budget against the performance needs of their system when considering either option.
User Experience and Feedback
User experience can greatly influence the choice between these coolers. The Thermalright Peerless Assassin 120 SE is praised for its effective cooling and ease of installation, making it a favourite among budget-conscious gamers and PC builders. Users appreciate its solid performance in maintaining lower CPU temperatures during intensive tasks. Meanwhile, the Corsair NAUTILUS 360 RS is lauded for its stylish design and exceptional cooling capabilities. The customisable LCD screen enhances user interaction, allowing for real-time monitoring of system performance, which many users find appealing. However, some may feel that the higher price tag does not justify the additional features, especially if they do not require extensive cooling performance.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE and the Corsair NAUTILUS 360 RS ultimately depends on your specific needs and budget. If you are looking for an affordable, reliable air cooler that delivers solid performance, the Thermalright Peerless Assassin 120 SE at £26.90 is an excellent choice. However, if you desire advanced cooling capabilities, aesthetic enhancements, and are willing to invest more, the Corsair NAUTILUS 360 RS, priced at £99.98, stands out as a premium option. Consider your cooling requirements, noise tolerance, and budget to make the best decision for your PC build.
