Dimension comparison
Overview of Products
In this comparison, we will look at the Thermalright Peerless Assassin 120 SE CPU Air Cooler and the Corsair iCUE LINK RX120 RGB 120mm PWM Fans. The Thermalright cooler is priced at £29.99, while the Corsair fans are more expensive at £54.99. Each product offers unique features tailored to different user needs, making them suitable for various cooling applications.
Design and Build Quality
The Thermalright Peerless Assassin 120 SE showcases a robust design with dimensions of 125(L)x135(W)x155(H)mm, making it a compact yet powerful cooling solution. Its dual tower design enhances cooling efficiency, while the use of aluminum and copper materials ensures durability. In contrast, the Corsair iCUE LINK RX120 fans feature a sleek design with magnetic connectivity, allowing easy installation and arrangement. The vivid RGB lighting adds an aesthetic appeal, enhancing the visual experience of your PC build.
Cooling Performance
Cooling performance is a critical factor when choosing between these two products. The Thermalright cooler can handle a TDP (Thermal Design Power) of 120 to 265W, making it suitable for a range of CPUs. It features 6 heat pipes that employ AGHP technology to improve cooling efficiency. The Corsair fans, on the other hand, can reach speeds of up to 2,100 RPM, providing airflow of up to 74.2 CFM. This makes them particularly effective at maintaining optimal temperatures, especially in high-performance setups with dense radiators.
Noise Levels
When considering noise levels, the Thermalright cooler operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a CPU cooler. This is an important aspect for users who prioritise a silent computing environment. The Corsair fans do not provide a specified noise level, but they are designed for high static pressure, which implies a focus on performance over silence. Users should consider their tolerance for noise when selecting between these two options.
Compatibility
Compatibility is another key area where these products differ. The Thermalright Peerless Assassin supports a wide range of CPU sockets, including Intel 115X, 1200, 1700, and AMD AM4. This broad compatibility ensures that it can be used with a variety of setups without requiring additional purchases. The Corsair iCUE LINK RX120 fans are designed to work seamlessly with the iCUE LINK system, allowing for easy connection and control. However, they are primarily intended to be used as part of a cooling solution rather than a standalone CPU cooler.
RGB Lighting and Aesthetics
Aesthetics play a significant role in modern PC builds, and here the Corsair fans excel. With eight RGB LEDs, they provide vibrant lighting effects that can be customised via the iCUE software, allowing users to sync lighting with other Corsair components. The Thermalright cooler, while functional, does not feature RGB lighting, making it less appealing for users seeking to enhance the visual aspect of their builds. Those prioritising aesthetics may find the Corsair fans more attractive.
Ease of Installation
Installation is a crucial factor for many users, and both products have their strengths. The Thermalright cooler comes with metal fasteners for both Intel and AMD platforms, ensuring a straightforward installation process. It includes all necessary mounting hardware and thermal paste. The Corsair fans utilise magnetic connectors, making it easy to link multiple fans together with minimal cable clutter. However, users need to ensure they have the iCUE LINK system hub for optimal performance, which could complicate installation for some.
Price and Value
In terms of price, the Thermalright Peerless Assassin 120 SE is significantly more affordable at £29.99 compared to the Corsair fans at £54.99. This price difference reflects the distinct use cases; the Thermalright cooler serves as a complete cooling solution, while the Corsair fans are primarily designed to enhance airflow and aesthetics. Users should assess their budget and specific cooling needs when considering the value of each product.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE CPU Air Cooler and the Corsair iCUE LINK RX120 RGB 120mm PWM Fans ultimately depends on your specific requirements. If you need an efficient and cost-effective CPU cooler that supports a range of sockets and operates quietly, the Thermalright cooler is an excellent choice. Conversely, if you are looking to enhance your system with high-performance fans featuring vibrant RGB lighting and excellent airflow, the Corsair fans may be worth the investment. Assess your priorities and budget to make the best decision for your setup.
