Overview of Thermalright Peerless Assassin 120 SE CPU Air Cooler

The Thermalright Peerless Assassin 120 SE CPU Air Cooler is a well-regarded choice for PC enthusiasts, boasting a current price of £26.90. This cooler is known for its effective cooling capabilities and compatibility with various Intel and AMD sockets, including LGA1700 and AM5, making it versatile for multiple builds. The design features double tower cooling with a total of six heat pipes, which enhances thermal performance, while the dual PWM fans provide airflow of up to 66.17 CFM at a noise level of 25.6 dB(A).

Thermalright's commitment to quality is evident in their 20 years of experience, focusing on computer accessories. The Peerless Assassin 120 SE is designed to provide optimal cooling while ensuring that installation is straightforward, given its inclusion of metal fasteners compatible with various platforms.

The Corsair iCUE LINK LX120-R RGB fans are priced at £64.99 and are designed to deliver not only effective cooling but also stunning aesthetics. With a maximum speed of 2,400 RPM, these fans can push an impressive airflow of 66.7 CFM, slightly surpassing the Thermalright cooler’s fan performance. The dual light loops featuring 18 RGB LEDs per fan offer extensive customisation options, allowing users to synchronise lighting with other iCUE devices for a cohesive look.

These fans also utilise a reversed rotor design, ensuring that the RGB lighting remains visible, enhancing the visual appeal of any build. With the inclusion of iCUE LINK bridge connectors, the LX120-R facilitates seamless connectivity, making it a strong contender for those prioritising both cooling efficiency and aesthetics.

Performance Comparison

In terms of cooling performance, both the Thermalright Peerless Assassin 120 SE and Corsair iCUE LINK LX120-R excel, but they cater to different needs. The Peerless Assassin features a total of six heat pipes and dual PWM fans, achieving a maximum airflow of 66.17 CFM, which is effective for typical CPU cooling scenarios. Meanwhile, the Corsair fans, with their higher RPM of up to 2,400, achieve a slightly higher airflow of 66.7 CFM, making them potentially more efficient in certain conditions.

When considering noise levels, the Thermalright cooler operates at a maximum of 25.6 dB(A), which is relatively quiet for a cooling solution. The Corsair fans, while not specified for noise output, emphasise quiet operation through their Magnetic Dome Bearing technology, suggesting a focus on reducing noise while maintaining performance.

Aesthetics and Design

Aesthetically, the Corsair iCUE LINK LX120-R takes the lead with its stunning RGB lighting and reversed rotor design. The dual light loops not only enhance visual appeal but also allow for customisation that can be synchronised with other Corsair devices, making it an excellent choice for gamers and PC builders focused on aesthetics.

In contrast, the Thermalright Peerless Assassin, while functional, does not feature RGB lighting, which may be a drawback for those seeking a visually striking build. Its design prioritises performance and compatibility over flashy aesthetics, appealing to users who prefer a more understated look.

Compatibility and Installation

The Thermalright Peerless Assassin 120 SE is compatible with a wide range of CPU sockets, including Intel's LGA1150 through LGA1851 and AMD's AM4 and AM5. This broad compatibility ensures that users can install it on various platforms without any issues, making it a versatile choice for many builds.

On the other hand, the Corsair iCUE LINK LX120-R fans are designed to integrate seamlessly into existing setups, particularly those using Corsair’s iCUE ecosystem. The included bridge connectors simplify the installation process, allowing users to connect multiple fans with just a single cable. However, compatibility is limited to systems that support these specific fans, which may not be as universally applicable as the Thermalright cooler.

Price-to-Performance Ratio

With a price of £26.90, the Thermalright Peerless Assassin 120 SE offers excellent value for users seeking effective CPU cooling without breaking the bank. Its performance and compatibility with various CPU sockets make it a practical investment for budget-conscious builders.

Conversely, the Corsair iCUE LINK LX120-R is priced at £64.99, making it a more expensive option. However, the added cost can be justified by its performance capabilities, aesthetic appeal, and the integration features of the iCUE ecosystem. For users who value these aspects, the higher price may be worth it, although it represents a significant investment compared to Thermalright's offering.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE and the Corsair iCUE LINK LX120-R comes down to your specific needs and preferences. If you prioritise cost-effectiveness, compatibility, and solid performance, the Thermalright cooler is an excellent choice at £26.90. However, if you value aesthetics, customisation options, and a slight edge in airflow performance, the Corsair fans at £64.99 may be worth the investment. Ultimately, both products cater to different segments of the market, allowing users to select based on their cooling needs and design preferences.
