Overview of the Products
The Corsair iCUE COMMANDER CORE XT and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler serve distinct purposes in the realm of CPU cooling solutions. The Corsair model, priced at £34.99, functions primarily as a fan and lighting controller, while the Thermalright cooler, available for £28.79, is designed for effective CPU cooling. This comparison explores the features and capabilities of each to determine which product may be more beneficial depending on user needs.
Design and Build Quality
The design of a cooling solution plays a significant role in its effectiveness and user experience. The Corsair iCUE COMMANDER CORE XT serves as a central hub for controlling up to six fans and RGB lighting, integrating seamlessly into a case. This model boasts precise PWM fan speeds and intelligent fan detection, allowing for a highly customisable setup. In contrast, the Thermalright Peerless Assassin 120 SE highlights its double tower design, utilising six heat pipes for superior cooling performance. With a weight of 0.97 kg, it is a robust option for any build, promising durability alongside aesthetic appeal with its vibrant ARGB lighting effects.
Cooling Performance
When evaluating cooling performance, the Thermalright Peerless Assassin 120 SE excels with its dual tower design and six heat pipes. This configuration is specifically engineered to counteract the inverse gravity effect, ensuring optimal performance whether installed vertically or horizontally. It achieves a maximum airflow of 66.17 CFM, which is significant for maintaining lower CPU temperatures during intensive tasks. Meanwhile, the Corsair iCUE COMMANDER CORE XT does not directly cool the CPU but rather manages the cooling process by optimising fan speeds. While it effectively controls up to six fans, its performance is contingent upon the fans being used, making a direct comparison challenging.
Fan Control and Customisation
Fan control and customisation are where the Corsair iCUE COMMANDER CORE XT truly shines. It allows users to connect and control up to six PWM fans, offering features such as Zero RPM mode to minimise noise under low loads. Furthermore, it supports a vast array of RGB lighting options with the capability to handle up to 264 RGB LEDs, ensuring a visually striking setup. In contrast, the Thermalright Peerless Assassin 120 SE comes with two PWM fans, which offer ARGB lighting but are limited in customisation compared to Corsair’s offering. This makes the Corsair unit a preferred choice for gamers and PC builders looking to create an immersive lighting experience.
Compatibility
Compatibility is crucial when selecting cooling solutions for a PC build. The Corsair iCUE COMMANDER CORE XT is compatible with various CORSAIR RGB fans and other RGB devices, making it a versatile option for users already invested in the Corsair ecosystem. On the other hand, the Thermalright Peerless Assassin 120 SE is compatible with a wide range of CPU sockets, including Intel’s latest 1700 and AMD's AM5, enhancing its versatility for different setups. It also comes with the necessary mounting hardware for easy installation, making it a user-friendly choice for both novice and experienced builders.
Noise Levels
Noise levels can significantly impact the user experience, especially in gaming and workstation environments. The Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a CPU air cooler, ensuring that users can enjoy a silent operation during critical tasks. In contrast, the Corsair iCUE COMMANDER CORE XT's Zero RPM mode effectively reduces noise at low loads, though its actual noise level during operation can vary based on the fans connected. Users seeking a quieter solution may prefer the Thermalright cooler, particularly if they are sensitive to noise.
User Experience and Software
The user experience is a pivotal factor when choosing between these two products. The Corsair iCUE COMMANDER CORE XT leverages the CORSAIR iCUE software, which provides an intuitive interface for monitoring temperatures and managing fan speeds and RGB lighting. This software enhances the overall experience, allowing for tailored performance and aesthetics. In contrast, the Thermalright Peerless Assassin 120 SE does not include proprietary software for fan control, relying instead on simpler PWM functionality. Users who value customisation and detailed control options may find the Corsair solution more appealing.
Price and Value
In terms of pricing, the Corsair iCUE COMMANDER CORE XT is £34.99, while the Thermalright Peerless Assassin 120 SE is slightly more affordable at £28.79. The difference in price reflects the distinct functionalities of each product. The Corsair unit offers extensive control and customisation, making it a worthwhile investment for those looking to enhance their system's aesthetics and cooling management. The Thermalright cooler, while less expensive, provides solid performance and compatibility, making it an excellent value for users focused primarily on CPU cooling without the additional features.
Which should you buy?
Choosing between the Corsair iCUE COMMANDER CORE XT and the Thermalright Peerless Assassin 120 SE ultimately depends on your specific needs. If you require a comprehensive solution for managing fan speeds and RGB lighting, the Corsair unit is the better option, offering extensive customisation and control. However, if your primary concern is effective CPU cooling at a lower price point, the Thermalright Peerless Assassin 120 SE presents a compelling choice with its strong cooling performance and quiet operation. Consider your priorities—be it aesthetics, noise levels, or cooling efficiency—when making your decision.
