Overview of the ARCTIC Freezer 36 A-RGB and Thermalright Peerless Assassin 120 SE

When comparing the ARCTIC Freezer 36 A-RGB with the Thermalright Peerless Assassin 120 SE, both CPU coolers offer unique features and specifications tailored for high-performance cooling. The ARCTIC Freezer is priced at £27.49, while the Thermalright Peerless is slightly cheaper at £26.90. This small price difference reflects their distinct technologies and cooling capabilities, appealing to various users in the competitive CPU cooling market.

Design and Build Quality

The ARCTIC Freezer 36 A-RGB showcases a single-tower design that efficiently utilises its four offset heat pipes to facilitate rapid heat transfer. Its innovative fan mounting system allows for easy installation and maintenance. In contrast, the Thermalright Peerless Assassin 120 SE features a double-tower design, which is generally recognised for enhanced cooling potential. With dimensions of 125mm x 135mm x 155mm, the Peerless is slightly bulkier, which could influence compatibility with certain cases. Both coolers appear robustly built, but the choice between a single-tower and double-tower design could significantly affect your cooling performance.

Cooling Performance

In terms of cooling performance, the ARCTIC Freezer 36 A-RGB is engineered for high-end CPUs, allowing for efficient heat dissipation via its pressure-optimised 120mm fans. The design optimises airflow through the heat sink, and the side-flow heat sink enhances ventilation. Meanwhile, the Thermalright Peerless Assassin employs six copper heat pipes with AGHP technology, ensuring efficient thermal management and addressing the inverse gravity effect. While both coolers are capable, the dual fans of the Peerless may provide a slight edge in sustained cooling under heavy loads.

Installation Process

The installation process is straightforward for both coolers, but they do have different requirements. The ARCTIC Freezer 36 A-RGB features an innovative Click-installation system, making it user-friendly, especially for those new to building PCs. However, it requires the original AMD mounting screws for installation on AMD sockets, which could be a drawback if those screws are missing. On the other hand, the Thermalright Peerless Assassin comes equipped with mounting hardware compatible with both Intel and AMD sockets, making it versatile. This ease of installation might appeal more to users looking for less hassle.

Noise Levels

Noise levels are an essential consideration for CPU coolers, especially for those building quiet systems. The ARCTIC Freezer 36 A-RGB operates with the promise of effective cooling, but specific noise levels are not mentioned in the features. The Thermalright Peerless Assassin, however, boasts a maximum noise level of 25.6 dB(A), ensuring a quiet operation even under load. If silence is a priority in your build, the Peerless may be the more attractive option based on the available data.

Compatibility

Both coolers are designed to accommodate a wide range of CPU sockets. The ARCTIC Freezer 36 A-RGB supports Intel LGA1851 and LGA1700 among others, with specific mention of needing original AMD mounting screws. The Thermalright Peerless Assassin supports a broader array of sockets, including Intel LGA1150 through LGA1851 and AMD AM4 and AM5. This wider compatibility with the Peerless Assassin may make it a more flexible choice for users with various setups.

Aesthetics and RGB Features

When it comes to aesthetics, the ARCTIC Freezer 36 A-RGB stands out with its addressable RGB lighting that can enhance the look of any build. This feature appeals to gamers and PC enthusiasts who wish to create a visually striking system. The Thermalright Peerless Assassin, while effective, does not specifically mention RGB features, which may make it less appealing for users prioritising aesthetics. If visual flair is essential to you, the ARCTIC Freezer's RGB integration is a significant advantage.

Which should you buy?

Both the ARCTIC Freezer 36 A-RGB and the Thermalright Peerless Assassin 120 SE have their unique strengths, catering to different user needs. If you prioritise aesthetics with RGB lighting and a user-friendly installation process, the ARCTIC Freezer is the better choice. However, if you seek superior compatibility, quieter operation, and potentially enhanced cooling performance, the Thermalright Peerless Assassin presents a compelling option at a slightly lower price of £26.90. Ultimately, your choice should depend on your specific requirements, including budget, cooling needs, and the importance of aesthetics in your build.
