Overview of Thermalright Peerless Assassin 120 SE CPU Air Cooler
The Thermalright Peerless Assassin 120 SE CPU Air Cooler is designed for effective cooling and compatibility across multiple platforms. With a current price of £26.90, it offers a robust solution for CPU enthusiasts. The cooler features a double tower design and is equipped with two PWM fans that can achieve a maximum airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A), making it a suitable choice for quiet performance. Its dimensions of 125x135x155 mm allow for efficient heat dissipation, and it supports both Intel and AMD sockets, enhancing its versatility in various builds.
Overview of Corsair iCUE COMMANDER CORE XT
The Corsair iCUE COMMANDER CORE XT is priced at £34.99 and acts as a smart hub for case fans and RGB lighting. It can control up to six PWM fans, providing precise fan speeds with a Zero RPM mode for quieter operations at low loads. Unlike traditional controllers, the COMMANDER CORE XT integrates seamlessly with the CORSAIR iCUE software, allowing for extensive RGB lighting customisation and intelligent fan detection, which simplifies setup. Furthermore, it includes two repositionable temperature sensors for accurate system monitoring, making it an essential tool for those who want to fine-tune their cooling and lighting setups.
Cooling Performance Comparison
In terms of cooling capabilities, the Thermalright Peerless Assassin 120 SE excels with its double tower design and dual 120 mm PWM fans. This configuration allows it to deliver impressive airflow levels of up to 66.17 CFM, which is essential for maintaining optimal CPU temperatures during demanding tasks. In contrast, while the Corsair iCUE COMMANDER CORE XT does not provide cooling itself, it is integral for managing fan speeds and optimising airflow in a system by controlling up to six fans. This means that while both products play different roles in cooling, the Thermalright cooler provides direct cooling performance, whereas the COMMANDER CORE XT enhances system cooling efficiency through intelligent fan control.
Compatibility and Installation
The Thermalright Peerless Assassin 120 SE is compatible with a wide range of CPU sockets, including Intel's LGA1150 to LGA1700 and AMD’s AM4 and AM5 platforms. This broad compatibility makes it a flexible choice for various builds. Installation is straightforward due to the included metal fasteners tailored for both Intel and AMD platforms. On the other hand, the Corsair iCUE COMMANDER CORE XT is designed to work with CORSAIR RGB fans and components, meaning that while it supports a variety of fans, it may require specific products for optimal functionality. This can limit its appeal to users who do not already possess CORSAIR components but offers a streamlined experience for those who do.
Noise Levels
When considering noise levels, the Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a CPU cooler. This is particularly beneficial for users who prioritise a silent computing environment. The Corsair iCUE COMMANDER CORE XT, while it itself does not produce noise, facilitates a Zero RPM mode for compatible fans, significantly reducing noise when system loads are low. This feature allows for a quieter operation during less demanding tasks, making it a great addition to any silent build. Both products, in their respective capacities, contribute to a quieter computing experience.
Aesthetics and Customisation
The Thermalright Peerless Assassin 120 SE is designed with performance in mind, with a functional yet straightforward appearance. It does not include RGB lighting, which may appeal to users who prefer a more minimalist look. In contrast, the Corsair iCUE COMMANDER CORE XT offers extensive RGB lighting customisation, controlling up to 264 RGB LEDs and supporting various RGB fans. This makes it an ideal choice for those wanting to create a vibrant and visually striking build. The aesthetic appeal of the COMMANDER CORE XT can enhance the overall look of a gaming or high-performance PC setup, while the Peerless Assassin focuses solely on cooling efficiency.
Price Consideration
The Thermalright Peerless Assassin 120 SE is priced at £26.90, making it an economical choice for users looking for effective CPU cooling without breaking the bank. In comparison, the Corsair iCUE COMMANDER CORE XT comes in at £34.99, which reflects its advanced features and smart capabilities. For consumers on a budget, the Peerless Assassin provides solid performance at a lower price point. However, those willing to invest more for enhanced control and customisation may find the extra cost of the COMMANDER CORE XT to be justified.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE CPU Air Cooler and the Corsair iCUE COMMANDER CORE XT ultimately depends on your specific needs. If you are looking for a reliable and effective CPU cooler with excellent performance at a budget-friendly price, the Peerless Assassin is the way to go. Conversely, if you prioritise fan control, RGB customisation, and intelligent monitoring capabilities, the COMMANDER CORE XT offers a sophisticated solution for optimising your cooling setup. Each product has its strengths, so consider your requirements carefully to make the best choice for your system.
