Price Comparison

The Corsair NAUTILUS 360 RS ARGB Liquid CPU Cooler is significantly more expensive than the Thermalright Peerless Assassin 120 SE CPU Air Cooler, priced at £109.99 compared to £26.90. This represents a striking difference of £83.09, suggesting that the Corsair cooler may offer advanced features justifying its premium price. The Thermalright cooler, at a much lower price point, can appeal to budget-conscious users who still seek quality performance. The substantial price difference raises questions about the specific benefits and features that the Corsair cooler provides to warrant its cost.

Design and Build Quality

In terms of design, the Corsair NAUTILUS 360 RS features a sleek and modern aesthetic, enhanced by its RGB lighting capabilities. Its design is not just for looks; it incorporates a convex cold plate which ensures maximum contact with the CPU, thereby improving cooling efficiency. On the other hand, the Thermalright Peerless Assassin 120 SE boasts a robust double tower cooling design, which is reinforced with metal fasteners for both Intel and AMD platforms. This dual design allows for greater cooling potential in a compact form factor. Both products are well-engineered, but the aesthetic appeal and RGB features of the Corsair cooler may attract gamers and enthusiasts.

Cooling Performance

The cooling performance of the Corsair NAUTILUS 360 RS is underscored by its efficient, low-noise pump that operates at a whisper-quiet 20 dBA while maintaining strong, low-noise cooling. It is designed to help CPUs reach their full potential, making it an excellent choice for high-performance builds. Conversely, the Thermalright Peerless Assassin 120 SE employs six 6mm heat pipes and dual PWM fans that can achieve a maximum airflow of 66.17 CFM, with noise levels capped at 25.6 dB(A). While both coolers are designed to maintain optimal CPU temperatures, the liquid cooling solution of the Corsair may provide superior thermal management, particularly under load.

Installation and Compatibility

The Corsair NAUTILUS 360 RS simplifies installation with its pre-applied thermal paste and convex cold plate, ensuring maximum contact with the CPU. Additionally, it features easy daisy-chained connections for its RS ARGB fans, streamlining setup and reducing cable clutter. In contrast, the Thermalright Peerless Assassin 120 SE is equipped with mounting solutions for a wide range of Intel and AMD sockets, ensuring compatibility across many platforms. Its installation process is straightforward, aided by its double tower design which allows for unrestricted RAM clearance. While both coolers are user-friendly, the Corsair's design may appeal more to those who prioritise aesthetics and ease of wiring.

Noise Levels

Noise levels are a critical factor for many PC builders, particularly in quiet environments. The Corsair NAUTILUS 360 RS operates at a remarkably low noise level of 20 dBA, making it an excellent choice for users seeking a silent operation. The Thermalright Peerless Assassin 120 SE, while slightly louder at 25.6 dB(A), still maintains a relatively quiet performance for an air cooler. For users with noise sensitivity, the Corsair model clearly has an advantage, providing a quieter cooling solution without sacrificing performance. This difference may be crucial for gamers or content creators who require a serene workspace.

Aesthetic Appeal

When it comes to aesthetics, the Corsair NAUTILUS 360 RS ARGB cooler stands out with its dynamic RGB lighting that can be controlled via a compatible motherboard. This feature not only enhances the visual appeal of a build but also allows for personalisation, making it a popular choice among gaming enthusiasts. In contrast, the Thermalright Peerless Assassin 120 SE focuses more on functionality than visual flair, with a clean and professional appearance. While both coolers are built with performance in mind, the Corsair's emphasis on RGB lighting could sway users who value aesthetic customisation in their builds.

Brand Reputation and Support

Corsair is a well-established brand in the gaming and PC hardware market, renowned for its high-quality products and customer support. Its reputation for performance and reliability makes the Corsair NAUTILUS 360 RS a trusted option for serious gamers and PC builders. Conversely, Thermalright, while not as widely recognised, has over 20 years of experience in the industry and has garnered a loyal following for its affordable yet effective cooling solutions. Both brands offer solid products, but Corsair's established reputation may give it an edge for users prioritising brand trust and support.

Which should you buy?

Deciding between the Corsair NAUTILUS 360 RS ARGB Liquid CPU Cooler and the Thermalright Peerless Assassin 120 SE CPU Air Cooler ultimately comes down to your specific needs and budget. If you are looking for high-performance cooling with exceptional aesthetics and are willing to invest in a premium product, the Corsair cooler is the superior choice. However, if you are on a budget and still want a reliable cooling solution, the Thermalright model provides excellent value for money without compromising significantly on performance. Your decision should reflect whether you prioritise aesthetics and advanced features or cost and fundamental cooling efficiency.
