Price Comparison
The Thermalright Peerless Assassin 140 Black CPU Cooler is substantially more affordable at C$54.90 compared to the CORSAIR Nautilus 360 RS LCD Liquid CPU Cooler, which costs C$224.99. This significant price difference of C$170.09 makes the Thermalright model an appealing choice for budget-conscious users. While the Nautilus offers advanced features, those seeking a more economical solution may find the Thermalright cooler to be a better fit without compromising essential cooling performance.
Design and Build Quality
In terms of design, the Thermalright Peerless Assassin features a twin-tower body with a height of 158mm, making it compatible with larger chassis while allowing for high-clearance memory and graphics card installations. The cooler is constructed with a mix of aluminium fins and pure copper heat pipes, which enhances its heat dissipation capabilities. On the other hand, the CORSAIR Nautilus 360 RS boasts a sleek, modern look with a customizable LCD screen that adds a unique aesthetic to your build. However, its liquid cooling design requires a more complex installation compared to the straightforward setup of the Thermalright cooler.
Cooling Performance
The Thermalright Peerless Assassin is equipped with dual PWM fans that can reach speeds of 1500 RPM, producing an air volume of 66.17 CFM while maintaining a noise level of ≤25.6 dB(A). This configuration provides effective cooling for the CPU during demanding tasks. In contrast, the CORSAIR Nautilus 360 RS uses high static pressure RS fans that are designed to push air efficiently through its larger radiator. The pump, operating at a whisper-quiet level of 20 dBA, ensures that coolant circulates effectively, thus maintaining optimal thermal performance. The combination of these features suggests that both coolers are capable of handling high-performance CPUs, but the Nautilus may have an edge in extreme cooling scenarios due to its liquid cooling design.
Installation Process
The installation process of the Thermalright Peerless Assassin is relatively straightforward, designed to accommodate a variety of CPU socket types including Intel and AMD platforms. The cooler comes with an all-metal fastener system, making it user-friendly for those new to CPU installation. In contrast, the CORSAIR Nautilus 360 RS may require more careful assembly due to its liquid cooling nature. While it comes with pre-applied thermal paste for easy setup, the need for proper mounting and management of tubing can complicate installation for less experienced users.
Noise Levels
Noise levels are a crucial aspect when choosing a CPU cooler, especially for users who prefer a quiet computing experience. The Thermalright Peerless Assassin operates at a maximum noise level of ≤25.6 dB(A), which is relatively quiet for an air cooler. Meanwhile, the CORSAIR Nautilus 360 RS operates even more quietly at just 20 dBA. This lower noise level can be particularly appealing for gamers or professionals who require a serene environment while working or playing. Both coolers offer commendable noise performance, but the Nautilus has a slight advantage in this category.
Aesthetic Appeal
Aesthetically, the CORSAIR Nautilus 360 RS stands out with its customizable LCD screen, allowing users to personalise the display with system information or custom graphics. This feature not only enhances the visual appeal of a gaming rig but also provides functional utility. The Thermalright Peerless Assassin, while more utilitarian in design, does not incorporate such visual flair. Users who prioritise aesthetics alongside performance may find the Nautilus a more attractive option, whereas those focused solely on performance may prefer the straightforward look of the Thermalright cooler.
Brand Reputation
Both Thermalright and Corsair have established themselves as reputable brands in the cooling market. Thermalright is known for its reliability and performance in air cooling solutions, making the Peerless Assassin a well-regarded choice among budget-friendly options. Corsair, on the other hand, is a leader in liquid cooling technology and gaming peripherals, with the Nautilus series being highly praised for its innovation and performance. The brand reputation may influence purchasing decisions, especially for those looking to invest in long-lasting and reliable cooling solutions.
Which should you buy?
Ultimately, the decision between the Thermalright Peerless Assassin 140 Black CPU Cooler and the CORSAIR Nautilus 360 RS LCD Liquid CPU Cooler hinges on individual needs and budget. The Thermalright cooler offers excellent performance at a significantly lower price of C$54.90, making it ideal for users seeking a cost-effective solution. Conversely, the CORSAIR Nautilus, priced at C$224.99, provides advanced features like liquid cooling and aesthetic enhancements that may appeal to enthusiasts willing to invest more for superior performance and visual appeal. If budget constraints are a priority, the Thermalright cooler is the clear choice; however, for those who desire cutting-edge technology and design, the Nautilus may be worth the investment.
