Brand Overview

When it comes to CPU coolers, brand reputation can significantly influence purchasing decisions. The ARCTIC Freezer 36 A-RGB is produced by ARCTIC, known for its high-performance cooling solutions. On the other hand, the Thermalright Assassin X120 SE ARGB is offered by Thermalright, a brand with over 20 years of experience in developing cooling products and accessories. Both brands are established players in the market, but ARCTIC is often recognised for its innovative designs and efficient cooling technologies, making the Freezer 36 a popular choice among gamers and PC builders.

Pricing

Price is a crucial factor when evaluating CPU coolers, and here, the Thermalright Assassin X120 SE ARGB comes out on top. Priced at £16.29, it is significantly more affordable than the ARCTIC Freezer 36, which retails for £27.49. This price difference of £11.20 may be appealing to budget-conscious consumers looking for effective cooling solutions without breaking the bank. Although the ARCTIC cooler offers advanced features, the Thermalright model provides an excellent price-to-performance ratio, especially for those not requiring the highest-end specifications.

Cooling Performance

Cooling performance is a vital aspect of any CPU cooler, and both models are designed to handle high-performance CPUs effectively. The ARCTIC Freezer 36 employs a single-tower design with four offset heat pipes, allowing for rapid heat transfer to the heat sink, where it is dissipated by its 120 mm fans. This design optimises cooling efficiency, particularly under heavy loads. Conversely, the Thermalright Assassin X120 SE utilises a unique AGHP technique with four heat pipes to combat inverse gravity effects, ensuring consistent performance whether in vertical or horizontal orientations. While both coolers excel, the Freezer 36 is engineered for high-end CPUs, which may provide a slight edge in extreme scenarios.

Noise Levels

Noise levels can greatly affect the user experience, particularly in quiet environments. The Thermalright Assassin X120 SE features PWM fans that operate at a maximum noise level of 25.6 dB(A), which is relatively quiet for a CPU cooler. In contrast, the ARCTIC Freezer 36 does not specify its noise levels, but its design includes pressure-optimised fans that are typically designed to operate efficiently while minimising sound. While the ARCTIC model may offer silent operation, the Thermalright cooler's explicitly low noise rating provides peace of mind for users concerned about noise interference during operation.

Installation

Ease of installation can be a deciding factor for many users. The ARCTIC Freezer 36 boasts an innovative Click-installation system, which simplifies the process of both installing the cooler and replacing the fans. Additionally, it is compatible with most 120 mm fans, allowing for flexibility in custom builds. The Thermalright Assassin X120 SE also offers a user-friendly installation experience; it comes equipped with metal fasteners for both Intel and AMD platforms, ensuring a secure fit. While both coolers are designed for straightforward installation, the ARCTIC’s unique mounting system may provide a slight advantage for those seeking convenience.

Compatibility

Compatibility with various CPU sockets is essential for ensuring that a cooler can be used with a wide range of systems. The ARCTIC Freezer 36 is compatible with both AM4 and AM5 sockets, but requires the original mounting screws from the motherboard for AMD installations. This may be a disadvantage if those screws are missing. In comparison, the Thermalright Assassin X120 SE supports a broader range of Intel sockets, including LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851, alongside AM4 and AM5 from AMD. This extensive compatibility makes the Thermalright cooler a more versatile option for users with various CPUs.

Aesthetics

Aesthetics play an increasingly important role in modern PC builds, and both coolers come with appealing designs. The ARCTIC Freezer 36 features A-RGB lighting that can enhance the visual appeal of a gaming rig. Its sleek single-tower design is not only functional but also adds a modern touch to any setup. Similarly, the Thermalright Assassin X120 SE is designed with colourful ARGB light effects, providing a vibrant look. While both products excel in aesthetics, the choice may ultimately come down to personal preference regarding their respective designs and lighting capabilities.

Which should you buy?

Ultimately, the choice between the ARCTIC Freezer 36 A-RGB and the Thermalright Assassin X120 SE ARGB will depend on your specific needs and budget. If you are seeking a cooler designed for high-performance CPUs with advanced features and are willing to invest a bit more, the ARCTIC Freezer 36 is an excellent option. However, if you are looking for a more affordable, versatile cooler that still delivers solid performance and a quieter operation, the Thermalright Assassin X120 SE is a compelling choice. Both coolers have their strengths, but your decision should align with your cooling requirements and budget constraints.
