Design and Aesthetics
The Corsair NAUTILUS 360 RS LCD Liquid CPU Cooler features a unique customisable LCD screen, adding a modern touch to any build. In contrast, the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler boasts vibrant ARGB lighting effects, making it visually appealing as well.

Both products cater to different aesthetic preferences, but the Corsair’s LCD screen offers more personalisation options, allowing users to display custom graphics or information.
Cooling Performance
When it comes to cooling performance, the Corsair NAUTILUS 360 RS stands out with its powerful, low-noise operation, ensuring effective CPU cooling under load. It operates at a whisper-quiet 20 dBA, allowing for a peaceful computing environment. The Thermalright Peerless Assassin 120 SE, with its dual tower design and six heat pipes, also promises solid cooling capabilities, with a maximum airflow of 66.17 CFM and a noise level of 25.6 dB(A). While both coolers provide decent cooling, the Corsair’s liquid cooling technology generally offers superior thermal management, especially for high-performance CPUs during intense tasks.
Installation and Compatibility
The installation process is crucial for a CPU cooler, and both the Corsair NAUTILUS 360 RS and the Thermalright Peerless Assassin 120 SE offer user-friendly features. The Corsair model comes with a convex cold plate and pre-applied thermal paste, ensuring maximum contact with the CPU for optimal heat transfer. Meanwhile, the Thermalright cooler supports a wide range of CPU sockets, including Intel’s 115X, 1200, 1700, and AMD’s AM4 and AM5, making it versatile for various builds. While the Corsair’s design may require more space due to its radiator, the Thermalright’s compatibility across multiple platforms makes it easier to install across different setups.
Noise Levels
Noise levels can significantly impact the user experience, especially in quiet environments. The Corsair NAUTILUS 360 RS operates at just 20 dBA, making it one of the quieter options available, perfect for users who prioritise silence. The Thermalright Peerless Assassin 120 SE, while still relatively quiet, operates at a noise level of up to 25.6 dB(A). Although this difference may seem minor, for those sensitive to sound, the Corsair’s quieter performance could be a deciding factor, particularly in a gaming or workstation setting where noise can be distracting.
Price Point
In terms of price, the Corsair NAUTILUS 360 RS is significantly more expensive at £99.98 compared to the Thermalright Peerless Assassin 120 SE, which retails at £28.79. This considerable price difference reflects the advanced features and technology of the Corsair model, including its liquid cooling system and customisable LCD screen. However, for budget-conscious consumers, the Thermalright offers excellent value for money, providing solid performance at a fraction of the cost. Ultimately, the choice may hinge on whether users are willing to invest in premium features for enhanced cooling performance and aesthetics.
Brand Reputation
Both Corsair and Thermalright have established themselves as reputable brands in the cooling market. Corsair is known for its innovative products and high-quality components, often favoured by gamers and PC enthusiasts for their performance. The NAUTILUS 360 RS exemplifies this reputation with its advanced design. On the other hand, Thermalright has built a strong following over more than 20 years, particularly within the gaming community. The Peerless Assassin 120 SE benefits from this heritage, combining reliable performance with effective cooling solutions. Brand loyalty and experience may play a role in a consumer's decision, with both brands offering distinct advantages.
User Experience
User experience is often shaped by the functionality and performance of the cooler. The Corsair NAUTILUS 360 RS provides a seamless experience with its efficient, low-noise pump and high flow rate, ensuring that coolant circulates effectively. The RS120 fans are designed to push air effectively through the radiator, contributing to its cooling prowess. Meanwhile, the Thermalright Peerless Assassin 120 SE, with its dual PWM fans operating at a speed of 1500 RPM, delivers robust airflow. However, users may find that the Corsair’s advanced features, such as the LCD screen, enhance their overall experience by allowing real-time monitoring of system performance.
Which should you buy?
The decision between the Corsair NAUTILUS 360 RS and the Thermalright Peerless Assassin 120 SE ultimately comes down to individual needs and budget. If you seek top-tier cooling performance and are willing to invest in a premium product with unique features like a customisable LCD screen, the Corsair is the clear choice. However, if you are looking for an affordable, effective air cooler that provides solid performance without breaking the bank, the Thermalright is an excellent option. Both products have their strengths, making them suitable for different types of users in the CPU cooling market.
