Overview of the Products
The Corsair iCUE COMMANDER CORE XT and the Thermalright Peerless Assassin 120 SE CPU Air Cooler are both designed to enhance your computer's cooling performance, yet they cater to different needs. Priced at £34.99 and £29.99, respectively, these products represent different approaches to cooling solutions—one focused on fan and RGB control, while the other emphasises air cooling efficiency.
Design and Build Quality
The Corsair iCUE COMMANDER CORE XT serves primarily as a fan and lighting controller, allowing users to manage up to six PWM fans and RGB components through the iCUE software. This product transforms a standard case into a smart case, incorporating precise PWM fan speeds and intelligent fan detection. In contrast, the Thermalright Peerless Assassin 120 SE is a robust air cooler with dimensions of 125mm x 135mm x 155mm, constructed using an aluminium heat sink and featuring two PWM fans. Its double tower design aims to provide superior cooling, making it well-suited for high-performance CPUs.
Cooling Performance
Cooling performance is crucial for any CPU cooler, and the Thermalright Peerless Assassin 120 SE boasts a TDP rating of 120 to 265W, indicating its capacity to handle demanding processors. The use of six 6mm heat pipes and a dual fan setup allows for efficient heat dissipation, with a maximum airflow of 66.17 CFM at a noise level of just 25.6 dB(A). On the other hand, the Corsair iCUE COMMANDER CORE XT does not provide direct cooling but enhances the cooling efficiency of connected PWM fans, allowing for better temperature control throughout the system with its two included temperature sensors.
Compatibility and Installation
When it comes to compatibility, the Thermalright Peerless Assassin 120 SE is designed to work with various CPU sockets, including Intel's 115X, 1200, and 1700, as well as AMD's AM4. It includes all necessary mounting hardware, making installation straightforward. Conversely, the Corsair iCUE COMMANDER CORE XT is compatible with numerous Corsair RGB fans and devices, facilitating easy integration into existing Corsair ecosystems. However, it is essential to note that it is not compatible with SP RGB Series fans, which may limit options for some users.
Software and Control Features
The Corsair iCUE COMMANDER CORE XT excels in software control, allowing users to customise RGB lighting and fan speeds via the iCUE software interface. This offers a level of control that enhances both aesthetics and performance. In contrast, the Thermalright Peerless Assassin 120 SE operates independently of software, relying solely on its physical components for cooling. This may appeal to users seeking a more straightforward, no-fuss installation, but it lacks the customisation options available with the Corsair product.
Price and Value
With a price of £34.99, the Corsair iCUE COMMANDER CORE XT is positioned as a premium accessory that provides extensive control over system cooling and RGB lighting. The Thermalright Peerless Assassin 120 SE, at £29.99, offers a compelling value proposition for users prioritising robust air cooling performance without the need for additional software. While the Corsair product provides advanced features, the Thermalright cooler delivers solid performance at a lower price, making it an attractive option for budget-conscious consumers.
Target Audience
The Corsair iCUE COMMANDER CORE XT is aimed at enthusiasts who value customisation and sophisticated control over their cooling and lighting setup. Its features are ideal for gamers and PC builders who want to create visually striking systems. Conversely, the Thermalright Peerless Assassin 120 SE caters to users who seek effective cooling solutions without the complexities of software. It is well-suited for those building high-performance workstations or gaming rigs that require efficient and reliable cooling.
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 prioritise advanced control, RGB lighting, and the ability to manage multiple fans, the Corsair product is the better choice. However, if you are looking for a straightforward, efficient air cooler with a strong cooling capacity for a lower price, the Thermalright option is more suitable. Each product has its strengths, making it essential to consider your individual requirements before making a purchase.
