Dimension comparison
Design and Aesthetics
The Thermalright Assassin X 120R is priced at $22.90, making it about 36% cheaper than the ARCTIC Freezer 36 A-RGB, which costs $35.80. This price difference might appeal to budget-conscious consumers. In terms of design, the Thermalright cooler features a digital screen top cover, which enhances its visual appeal. The ARCTIC cooler, on the other hand, boasts digital ARGB lighting with 12 LEDs, delivering a vibrant and uniform illumination.
Both coolers emphasize aesthetics alongside performance, but the ARCTIC cooler's lighting system may attract users seeking a more visually striking setup. The Thermalright's digital display adds a modern touch, catering to those who appreciate functionality and style.
Cooling Performance
The ARCTIC Freezer 36 A-RGB is engineered for high-performance cooling with its 200–2000 RPM fan speed and four heat pipes. This configuration allows for efficient heat transfer and effective dissipation, especially crucial for high-end CPUs. In contrast, the Thermalright Assassin X 120R features a fan speed capped at 2000 RPM, which, while robust, does not offer the same range as the ARCTIC cooler.
Both products utilize four heat pipes, but the ARCTIC cooler's ability to adjust its RPM dynamically allows it to adapt to varying thermal loads, potentially offering superior cooling efficiency during demanding tasks. Users looking to push their CPUs to the limit might prefer the ARCTIC cooler for its enhanced performance capabilities.
Noise Levels
When considering noise levels, the Thermalright Assassin X 120R has designed its PWM fan to operate quietly, thanks to silicone corner pads that reduce rotational noise. This focus on minimizing sound can be beneficial for users who prioritize a quieter computing environment. The ARCTIC Freezer 36 A-RGB, while also designed for efficient cooling, does not provide specific information regarding its noise output.
Given that both models aim for optimal performance, the Thermalright's explicit noise reduction features may appeal to users who are sensitive to fan noise. However, without detailed noise specifications for the ARCTIC, it’s difficult to make a direct comparison in this area.
Installation Process
The ARCTIC Freezer 36 A-RGB features an innovative click installation system that simplifies the installation process, making it easier for users to set up or replace fans. This design consideration can save time and reduce frustration during installation. In contrast, the Thermalright Assassin X 120R does not highlight any unique installation features.
For those who may not have extensive experience with CPU cooler installation, the ARCTIC cooler's user-friendly system may provide a more straightforward experience. This ease of installation could be a significant factor for less tech-savvy users looking for hassle-free assembly.
Compatibility
The ARCTIC Freezer 36 A-RGB is compatible with Intel's LGA1851 and LGA1700 sockets, ensuring it can accommodate a wide range of modern CPUs. The Thermalright Assassin X 120R expands this compatibility further, supporting AM4/AM5 sockets alongside Intel's LGA1700, 1851, 1150, 1151, and 1200. This broad compatibility makes the Thermalright cooler a versatile choice for various builds.
For users looking to upgrade or build a new system, the Thermalright Assassin X 120R may offer an edge in terms of compatibility with a greater number of socket types. This could be particularly appealing for those working with different platforms or planning future upgrades.
Build Quality
Both coolers are constructed with high-quality materials, but the ARCTIC Freezer 36 A-RGB emphasizes its fluid dynamic bearing technology, which enhances longevity and performance. The Thermalright Assassin X 120R employs industrial-grade materials and S-FDB bearings, promising durability and stability during operation.
While both brands focus on quality, the specific mention of fluid dynamic bearings in the ARCTIC cooler suggests a higher level of engineering aimed at reducing wear and tear. Users who prioritize build quality may find the ARCTIC cooler slightly more appealing due to this advanced bearing technology.
Price-to-Performance Ratio
The ARCTIC Freezer 36 A-RGB is priced at $35.80, while the Thermalright Assassin X 120R comes in at a lower $22.90. This significant price difference of approximately $12.90 means that the Thermalright offers better value for those on a budget, without sacrificing essential cooling features.
Despite the lower price, the Thermalright cooler still packs a robust performance with its 2000 RPM fan and four heat pipes. Users looking for a balance between performance and cost may find the Thermalright Assassin X 120R to be a more economically sensible choice, especially for mid-range builds.
Which should you buy?
Choosing between the ARCTIC Freezer 36 A-RGB and the Thermalright Assassin X 120R largely depends on your specific needs and budget. If you prioritize high-performance cooling, advanced features like dynamic RPM adjustment, and striking ARGB lighting, the ARCTIC Freezer 36 A-RGB is a solid option worth the investment. However, for users who are more budget-conscious and looking for a reliable cooler with a digital display and good compatibility across various platforms, the Thermalright Assassin X 120R presents an attractive choice at a lower price point. Ultimately, both coolers have their merits, and the decision should reflect your cooling requirements and aesthetic preferences.
