Dimension comparison
Overview of the Products
In this comparison, we will look at the CORSAIR RS120-R ARGB 120mm PWM Reverse Flow Fan and the ARCTIC Liquid Freezer III Pro 240 AIO CPU Cooler. The former is priced at £24.99, while the latter is significantly more expensive at £56.49. This stark price difference reflects their different roles within a PC cooling system—one focusing on case airflow and aesthetics, while the other is a comprehensive CPU cooling solution.
Design and Aesthetics
The CORSAIR RS120-R fan features vibrant and customisable ARGB lighting, with eight LEDs per fan that can be controlled via an ARGB-compatible motherboard. This is particularly appealing for those who wish to enhance the visual appeal of their builds. In contrast, the ARCTIC Liquid Freezer III Pro 240 does not focus on aesthetics but rather on efficient cooling performance. Its design includes a native offset mounting that optimises heat transfer from the CPU. While both products serve a purpose in cooling, the RS120-R prioritises visual flair, making it more suitable for users who want to showcase their builds.
Cooling Performance
When it comes to cooling performance, the CORSAIR RS120-R fan can achieve speeds up to 2,100 RPM and provides airflow of up to 65.8 CFM. This is suitable for case ventilation and can effectively push air through obstructions, thanks to its high static pressure of 2.81 mm H2O. The ARCTIC Liquid Freezer III Pro 240, however, is designed for CPU cooling with a focus on high performance under load. Its P12 PRO fan offers more power at any speed and is particularly effective at low speeds, making it quieter while still delivering efficient cooling. The Liquid Freezer's fan design is optimised for high-load performance, indicating its superior capabilities in thermally demanding scenarios.
Installation and Compatibility
The CORSAIR RS120-R is compatible with standard ARGB connections, requiring an ARGB-compatible motherboard for full lighting control. Its installation is straightforward, making it accessible for PC builders of all experience levels. The ARCTIC Liquid Freezer III Pro 240, on the other hand, features a contact frame tailored for Intel LGA1851 and LGA1700 sockets, ensuring efficient heat dissipation and longer CPU life. Its integrated cable management simplifies the installation process by reducing visible cables, which can be a plus for users concerned with aesthetics. While both products are designed to be user-friendly, the Liquid Freezer offers a more comprehensive solution for CPU cooling, albeit with a slightly more complex installation due to its AIO nature.
Noise Levels
The CORSAIR RS120-R fan offers precise PWM performance, allowing users to adjust fan speeds based on cooling needs, which can lead to quieter operation during less demanding tasks. While specific noise levels aren't provided, the ability to run at lower RPMs hints at a quieter performance when necessary. On the other hand, the ARCTIC Liquid Freezer III Pro 240 is noted for being quieter than its predecessor, especially at low speeds. Its design aims to provide effective cooling without generating excessive noise, making it suitable for silent PC builds. Both products offer features that help manage noise levels, but the Liquid Freezer is specifically engineered to maintain performance with minimal sound.
Price Consideration
The price difference between the CORSAIR RS120-R at £24.99 and the ARCTIC Liquid Freezer III Pro 240 at £56.49 is substantial. The RS120-R offers a budget-friendly option for users looking to improve case airflow and aesthetics without breaking the bank. Conversely, the Liquid Freezer’s higher price reflects its advanced technology and cooling capabilities tailored for demanding CPU workloads. This makes it more appropriate for enthusiasts or professionals who require superior cooling performance and are willing to invest more for that advantage.
Target Audience
The CORSAIR RS120-R is aimed at gamers and PC builders who prioritise aesthetics alongside adequate airflow. Its ARGB features cater to those who enjoy customisation and want to enhance their builds visually. In contrast, the ARCTIC Liquid Freezer III Pro 240 is targeted at serious gamers and overclockers who need robust CPU cooling and are less concerned with aesthetics. Its advanced cooling technology and higher performance capabilities justify its price point, making it a better fit for users with high thermal demands.
Which should you buy?
Choosing between the CORSAIR RS120-R and the ARCTIC Liquid Freezer III Pro 240 ultimately depends on your specific needs. If you are looking for a budget-friendly cooling solution that enhances your system's aesthetics, the CORSAIR RS120-R is a compelling choice. However, if you require high-performance cooling for a CPU under heavy loads and are willing to invest more, the ARCTIC Liquid Freezer III Pro 240 is the better option. Consider your priorities, whether they be cost, aesthetics, or thermal performance, to make the best decision for your build.
