Overview of the Products
The Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright AXP90 X47 Full Low Profile CPU Cooler are two distinct CPU cooling solutions catering to different needs and preferences. The Assassin X 120R is currently priced at $24.90, while the AXP90 X47 is available for $33.99, making the former about 17% cheaper. This price difference reflects their varying designs, features, and target applications.
Design and Aesthetics
The design of the Thermalright Assassin X 120R is not only functional but also visually appealing, featuring a digital screen top cover that displays real-time CPU and GPU temperatures and usage. Its height of 151mm allows for a substantial heat dissipation area, making it suitable for most cases without sacrificing performance. In contrast, the AXP90 X47 takes a low-profile approach with a total height of just 47mm, which is ideal for compact builds. While the AXP90 offers a more understated design, it lacks the aesthetic flair of the Assassin X 120R's digital display.
Performance and Cooling Efficiency
When it comes to cooling performance, the Thermalright Assassin X 120R utilizes a 2000 RPM fan and four heat pipes to effectively dissipate heat. With an air volume of 70.84 CFM and a noise level of 29.8 dB(A), it provides robust cooling suitable for high-performance CPUs. On the other hand, the AXP90 X47 also features four heat pipes but employs a 92mm PWM fan that operates at a lower airflow of 42.58 CFM and a noise level of just 22.4 dB(A). This makes the AXP90 quieter but potentially less effective at cooling under heavy loads compared to the Assassin X 120R.
Compatibility and Installation
The Thermalright Assassin X 120R supports a wide range of sockets, including Intel LGA 1851, 1700, 1150, and AMD AM4/AM5. Its comprehensive compatibility ensures that it can fit into various systems, making it a versatile choice. Installation is straightforward, aided by the included accessories and manuals. The AXP90 X47 is also compatible with Intel LGA 1150, 1151, 1200, and AMD AM4/AM5 sockets, but its low-profile design is particularly advantageous for smaller cases. Both coolers come with clear installation instructions, making the setup process user-friendly.
Noise Levels
The noise levels of CPU coolers are critical for users looking for a quiet computing experience. The Thermalright AXP90 X47 operates at a maximum noise level of 22.4 dB(A), making it an excellent choice for users who prioritize silence in their builds. In contrast, the Assassin X 120R has a slightly higher operating noise level of 29.8 dB(A). While the difference may not be significant for some users, those sensitive to noise might prefer the quieter operation of the AXP90.
Build Quality and Materials
The materials used in both coolers reflect their intended use cases. The Assassin X 120R features an aluminum heat sink and a PWM fan designed for high performance, while the AXP90 X47 boasts a pure copper base that enhances thermal conductivity. The AXP90 also includes a plating anti-oxidation protective layer, which helps prevent corrosion and prolongs the cooler's lifespan. Both coolers are made with quality materials, but the AXP90's copper base may provide a slight edge in terms of heat transfer efficiency.
User Experience and Feedback
While user feedback is not explicitly provided in the product data, the features of both coolers suggest a focus on user satisfaction. The Assassin X 120R's digital screen adds a modern touch and allows users to monitor temperatures easily, while the AXP90 X47's low noise levels and compact design make it appealing for smaller builds. Each cooler has its strengths, and user experiences will likely vary based on individual needs and system configurations.
Which should you buy?
Choosing between the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright AXP90 X47 Full Low Profile CPU Cooler ultimately depends on your specific requirements. If you prioritize aesthetics, robust cooling performance, and broader compatibility, the Assassin X 120R is the better option at a price of $24.90. However, if you need a compact, quieter solution for a small form factor build, the AXP90 X47, priced at $33.99, offers excellent performance and a lower noise level. Consider your case size, noise tolerance, and cooling needs to make the best decision for your setup.
