Overview of the Products
In this comparison, we will look at two CPU coolers from Thermalright: the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright AXP90 X47 Full Low Profile CPU Cooler. Both coolers offer distinct features and cater to different user needs, with the Assassin X 120R priced at C$32.90 and the AXP90 X47 available for C$43.39. Choosing the right cooler depends on your specific requirements, such as size constraints, noise levels, and aesthetic preferences.
Cooling Performance
The Thermalright Assassin X 120R boasts a fan speed of 2000 RPM and an impressive air volume of 70.84 CFM, which contributes to its effective heat dissipation capabilities. This cooler is designed for users seeking robust cooling performance in standard cases. Conversely, the AXP90 X47 features a slightly higher fan speed of 2700 RPM but with a lower air volume of 42.58 CFM. While both coolers are efficient, the Assassin X 120R is better suited for high-performance cooling, especially in larger setups, whereas the AXP90 X47 is optimized for smaller builds without compromising on cooling.
Design and Aesthetics
The Assassin X 120R stands out with its digital ARGB lighting, offering a visually appealing design that allows for light synchronization with compatible motherboards. This cooler's dimensions of 120x71x151 mm make it compatible with most cases while maintaining aesthetic appeal. In contrast, the AXP90 X47 features a more utilitarian design at just 94.5x95x47 mm, prioritizing form factor and low profile over flashy aesthetics. Its compact size makes it ideal for HTPC and ITX builds, where space is limited, but it lacks the visual flair of the Assassin X 120R.
Noise Levels
When considering noise levels, the Thermalright Assassin X 120R operates at a maximum noise level of 29.8 dB(A). This is relatively quiet for a cooler of its performance class. On the other hand, the AXP90 X47 operates even quieter at 22.4 dB(A), making it a suitable choice for users who prioritize silent operation in compact builds. If noise is a critical factor for your setup, the AXP90 X47 provides a quieter cooling solution without compromising on essential cooling capabilities.
Compatibility
The Assassin X 120R is compatible with a wide range of sockets, including Intel LGA 1851, 1700, and AMD AM4/AM5. It also comes with installation accessories to facilitate setup. The AXP90 X47 also supports various CPU sockets, including Intel LGA 1700 and AMD AM4/AM5, and is designed to be easily installed with its included mounting fasteners. While both coolers offer broad compatibility, the Assassin X 120R provides slightly more flexibility for users planning to upgrade their systems in the future.
Material and Build Quality
The Assassin X 120R features an aluminum heat sink that is lightweight and effective at heat dissipation. Its construction ensures durability and efficiency. In contrast, the AXP90 X47 stands out with its pure copper radiator, which enhances oxidation resistance and thermal conductivity. This factor can significantly improve thermal performance, especially in low-profile designs where heat dissipation is critical. Users looking for the best material for heat management may find the AXP90 X47's copper construction more appealing, despite its higher price point.
User Experience and Installation
Both coolers are designed for ease of installation, with the Assassin X 120R providing a detailed manual and video for guidance. Its compatibility with modern sockets means that most users will find installation straightforward. The AXP90 X47 similarly includes installation instructions and is designed to be user-friendly, especially for compact builds. However, the need to use the motherboard's original backplate for AMD installations may pose a slight inconvenience for some users of the Assassin X 120R.
Price Comparison
The Thermalright Assassin X 120R is priced at C$32.90, making it an attractive option for users seeking a performance cooler without breaking the bank. In contrast, the AXP90 X47 is priced higher at C$43.39, reflecting its low-profile design and copper construction. While the AXP90 X47 may offer superior materials for thermal performance, the price difference may deter budget-conscious consumers. Ultimately, the choice between these two coolers may come down to a balance between budget and the specific needs of the computer build.
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 comes down to your specific needs and preferences. If you require high-performance cooling with an aesthetic touch, the Assassin X 120R offers greater air volume and visual appeal at a lower price. However, if you are building a compact system where space is a constraint and you prefer quieter operation, the AXP90 X47 is an excellent choice with its low-profile design and superior copper material. Assess your priorities—whether it's performance, aesthetics, noise levels, or compatibility—to make the best decision for your build.
