Overview of the Products

When comparing the CORSAIR RS120-R ARGB 120mm PWM Reverse Flow Fan and the Thermalright Assassin X120 SE ARGB CPU Air Cooler, it’s essential to understand their core functionalities. The CORSAIR fan is designed primarily for optimising airflow and aesthetics in PC builds, while the Thermalright cooler focuses on efficient CPU cooling performance. Priced at £24.99, the CORSAIR fan offers advanced features like vibrant ARGB lighting and PWM performance, whereas the Thermalright cooler, at £16.29, is tailored for CPU thermal management with a focus on compatibility and quiet operation.

Design and Aesthetics

The design elements of the CORSAIR RS120-R fan centre around its reverse rotor technology, allowing for flawless RGB lighting visibility, even when mounted as an intake fan. This feature is particularly appealing for users looking to enhance their PC’s visual appeal. With eight LEDs per fan, users can enjoy customisable lighting effects, contributing to a vibrant setup. On the other hand, the Thermalright Assassin X120 SE presents a more traditional CPU cooler design, emphasising functionality over aesthetics. While it includes colourful ARGB lighting effects, its primary goal is thermal efficiency rather than visual flair, making it suitable for users who prefer a more understated appearance.

Performance Capabilities

In terms of performance, the CORSAIR RS120-R can achieve fan speeds of up to 2,100 RPM, providing an impressive airflow of 65.8 CFM. This high airflow capability is particularly beneficial for maintaining optimal system temperatures, especially in high-performance setups. Conversely, the Thermalright Assassin X120 SE features a fan speed of 1,550 RPM, with a maximum airflow rating of 66.17 CFM. While the airflow is slightly higher than the CORSAIR fan, the lower RPM indicates a quieter operation, as it maintains a noise level of ≤25.6 dB(A). Thus, users prioritising quiet performance may find the Thermalright cooler more appealing.

Cooling Efficiency

Cooling efficiency is a critical factor for both products. The CORSAIR RS120-R is designed with high static pressure capabilities of 2.81 mm H2O, enabling it to push air through obstructions effectively. This feature makes it suitable for cooling radiators and enhances its overall effectiveness in maintaining system temperatures. The Thermalright Assassin X120 SE, however, utilises a unique AGHP technique with four 6mm heat pipes to combat inverse gravity effects, ensuring efficient heat dissipation regardless of orientation. This design gives it a significant advantage in terms of consistent cooling performance, especially in various case layouts.

Noise Levels

Noise levels are an essential consideration for many PC builders. The CORSAIR RS120-R, operating at higher speeds, may generate more noise, especially when pushed to its maximum of 2,100 RPM. However, its PWM performance allows users to adjust speeds for quieter operation when needed. In contrast, the Thermalright Assassin X120 SE is designed for low-noise operation, achieving a maximum noise level of just 25.6 dB(A). This quieter performance is ideal for users who value a silent computing experience, particularly during intensive workloads or gaming sessions.

Compatibility and Installation

Compatibility is a crucial factor for any cooling solution. The CORSAIR RS120-R is versatile, fitting various PC builds and available in black or white to match user preferences. However, it is crucial to ensure that the motherboard supports ARGB connections for optimal usage. The Thermalright Assassin X120 SE excels in this category, as it comes with mounting hardware for both Intel and AMD platforms. Supporting multiple CPU sockets, including the latest Intel LGA 1700 and AMD AM5, it ensures broad compatibility, making it an excellent choice for a wide range of setups.

Brand Reputation

Both brands have established themselves in the cooling market, but they cater to slightly different audiences. Corsair is known for its premium-quality components with a strong focus on aesthetics and performance, making it a favourite among gamers and PC enthusiasts. The CORSAIR RS120-R exemplifies this brand ethos with its attention to lighting and airflow. Thermalright, with over 20 years of experience, has built a reputation for producing reliable and effective cooling solutions. The Assassin X120 SE reflects this commitment to quality, focusing on delivering excellent thermal performance with a quieter operation, appealing to users looking for dependable CPU cooling.

Which should you buy?

Deciding between the CORSAIR RS120-R ARGB fan and the Thermalright Assassin X120 SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you are looking for an aesthetically pleasing fan that offers high airflow and customisable RGB lighting, the CORSAIR RS120-R is an excellent choice at £24.99. However, if your priority is efficient CPU cooling with quiet operation and broad compatibility at a lower price of £16.29, the Thermalright Assassin X120 SE is the better option. Both products excel in their respective areas, ensuring that users can find a solution that fits their individual requirements.
