Dimension comparison
Overview of the ARCTIC Freezer 36 and Thermalright Peerless Assassin 120 SE ARGB CPU Air Coolers
The ARCTIC Freezer 36 is priced at £22.99, while the Thermalright Peerless Assassin 120 SE ARGB is slightly more expensive at £28.79. Both models are designed to provide efficient cooling for high-performance CPUs, but they employ different technologies and features to achieve their cooling capabilities.
The ARCTIC Freezer 36 boasts a single-tower design with four offset heat pipes, optimising heat transfer and ensuring that even high-end CPUs are kept cool. In contrast, the Thermalright Peerless Assassin features a dual-tower design and is equipped with six heat pipes, enhancing its cooling potential. The difference in design and price reflects the performance focus of each cooler, catering to various user needs.
Design and Build Quality
In terms of design, the ARCTIC Freezer 36 features a side-flow heat sink that enhances airflow through the case, promoting better cooling efficiency. Its innovative fan mounting system allows for easy installation or replacement of fans. Conversely, the Thermalright Peerless Assassin 120 SE ARGB has a more complex double-tower design, which not only enhances thermal performance but also incorporates ARGB lighting for aesthetic appeal.
The materials used in both coolers are geared towards durability and performance. The ARCTIC Freezer 36 utilises a robust single-tower structure, while the Thermalright Peerless Assassin employs a full electroplating reflow welding process for its heat pipes, which may improve longevity and reliability under heavy load. The choice between these designs will depend largely on personal preferences for aesthetics and installation complexity.
Cooling Performance
Cooling performance is a crucial factor for CPU coolers, and both the ARCTIC Freezer 36 and Thermalright Peerless Assassin are designed to manage heat effectively. The ARCTIC Freezer 36 utilises four offset heat pipes and a pressure-optimised 120 mm fan, promoting rapid heat transfer and efficient dissipation. This cooler is particularly well-suited for high-end CPUs, where maintaining lower temperatures can result in improved performance.
On the other hand, the Thermalright Peerless Assassin boasts six heat pipes and two PWM fans, allowing for greater airflow and potentially lower temperatures under load. With a maximum airflow of 66.17 CFM and a noise level of only 25.6 dB(A), it strikes a balance between quiet operation and effective cooling. Users seeking exceptional cooling performance may gravitate towards the Thermalright, while those prioritising cost-effectiveness might favour the ARCTIC.
Compatibility and Installation
Both coolers offer broad compatibility with various CPU sockets, making them versatile choices for many builds. The ARCTIC Freezer 36 is compatible with Intel LGA1851 and LGA1700 sockets, as well as AMD AM4 and AM5, but requires the original AMD mounting screws, which can be a drawback if those screws are missing.
The Thermalright Peerless Assassin also supports a wide range of sockets, including Intel 115X/1200/1700 and AMD AM4/AM5. It comes equipped with the necessary mounting plates for different CPU socket platforms, simplifying the installation process. For users who may not have all the mounting hardware on hand, the Thermalright's inclusive mounting accessories could be a significant advantage.
Noise Level and Fan Efficiency
When it comes to noise levels, the ARCTIC Freezer 36 does not specify a decibel rating, but its design is geared towards optimising airflow quietly. The Thermalright Peerless Assassin, however, explicitly mentions a maximum noise level of 25.6 dB(A), indicating that it is designed to operate quietly even under load.
Both coolers aim for efficient cooling while minimising noise, but the Thermalright's PWM fans and defined noise specifications provide a clearer picture of its quiet operation. Users who prioritise silent computing may find the Thermalright a more appealing option, especially in noise-sensitive environments.
Aesthetics and RGB Features
Aesthetics can play a significant role in a user's selection, particularly for those who enjoy building visually striking systems. The Thermalright Peerless Assassin stands out with its ARGB lighting, which adds a vibrant touch to any build. The lighting can be synchronised with other RGB components, making it an attractive choice for gamers and PC enthusiasts looking for a cohesive appearance.
In contrast, the ARCTIC Freezer 36 focuses more on functionality and performance, with a design that prioritises cooling efficiency over visual flair. While it may lack the RGB features of the Thermalright, its sleek design is still appealing to those who prefer a more understated look. Ultimately, the choice of aesthetics will depend on personal preference and the overall theme of the user's build.
Price Comparison and Value
The ARCTIC Freezer 36 is priced at £22.99, making it the more budget-friendly option between the two. This cooler offers good performance for its price, particularly for users with moderate cooling needs.
On the other hand, the Thermalright Peerless Assassin 120 SE ARGB, priced at £28.79, provides advanced features such as dual towers, ARGB lighting, and potentially superior cooling performance. Users willing to invest a bit more may find that the additional features justify the higher price point.
When assessing value, it is essential to consider the specific needs of your build. For users seeking a reliable and cost-effective cooling solution, the ARCTIC Freezer 36 may be the better choice, while those looking for enhanced performance and aesthetics may prefer the Thermalright.
Which should you buy?
The decision between the ARCTIC Freezer 36 and the Thermalright Peerless Assassin 120 SE ARGB ultimately hinges on your specific requirements and budget. If you seek an efficient, budget-friendly cooler that excels in performance for high-end CPUs, the ARCTIC Freezer 36 is a solid choice. Its innovative design allows for efficient cooling without breaking the bank.
Conversely, if you desire superior cooling performance, enhanced aesthetics with ARGB lighting, and are willing to pay a bit more, the Thermalright Peerless Assassin stands out with its advanced features and dual-tower design. Both coolers cater to different needs, so assess your priorities carefully before making a decision.
