Overview of the Products
The AMD AM4 Backplate - CPU Heatsink Bracket is priced at $6.99, while the Thermalright AXP90 X47 Full Low Profile CPU Cooler is considerably more expensive, at $33.99. This price difference of $27.00 highlights a significant disparity in their intended use and capabilities. The backplate is a specialized mounting solution for AMD's AM4 socket, designed for secure heatsink installation, whereas the Thermalright cooler serves as a comprehensive cooling solution for various CPU platforms, including both AMD and Intel systems.
Design and Build Quality
The AMD AM4 Backplate is precision-crafted for a specific purpose, facilitating secure mounting for heatsinks on AM4 motherboards. It is constructed with a combination of copper and high-quality ABS plastic, emphasizing heat dissipation. In contrast, the Thermalright AXP90 X47 features an ultra-compact design with a total height of only 47mm, making it suitable for small computer builds. Its pure copper base and a 92mm PWM fan offer excellent heat conductivity and low noise levels. The distinct design of each product reflects their primary functions: the backplate focuses solely on mounting, while the cooler emphasizes efficient thermal management.
Heat Dissipation Performance
The AMD AM4 Backplate enhances heat dissipation by ensuring optimal contact between the CPU and heatsink. However, it does not act as a cooling solution on its own, as it lacks an integrated fan. In contrast, the Thermalright AXP90 X47 features four heat pipes and a 92mm PWM fan, which ensures superior heat transfer from the CPU. The fan operates at a noise level of only 22.4 dB(A) while delivering an airflow of 42.58 CFM, making it an effective choice for maintaining lower temperatures during intensive computing tasks. Therefore, while the backplate aids in heat management, the cooler provides active cooling capabilities.
Compatibility and Use Cases
The AMD AM4 Backplate is exclusively compatible with AM4 socket motherboards, making it a specialized component for users with AMD CPUs. It is ideal for individuals who need to replace or upgrade their mounting hardware without altering their cooling solutions. On the other hand, the Thermalright AXP90 X47 is versatile, supporting not only AMD AM4 but also AM5 and various Intel sockets (LGA 1150/1151/1200/1700). This broad compatibility makes the cooler suitable for a wide range of builds, catering to users who may switch between different CPU brands or models in the future.
Installation Process
The installation of the AMD AM4 Backplate is straightforward, as it is designed specifically for easy mounting on AM4 motherboards. Users can simply replace their existing backplate without requiring additional tools or modifications. Conversely, the Thermalright AXP90 X47, while compact, may involve a more intricate installation process due to its cooling components and multiple compatibility options. Users must ensure proper alignment of the cooler with their specific CPU socket, which could require additional effort compared to the simpler backplate installation.
Noise Levels
The AMD AM4 Backplate does not produce any noise since it does not include a fan; its function is purely mechanical in securing heatsinks. In contrast, the Thermalright AXP90 X47, with its PWM fan, operates at a noise level of just 22.4 dB(A), which is notably quiet for a CPU cooler. This low noise level makes the Thermalright option suitable for users seeking a quiet computing environment, especially in compact builds where noise can be more noticeable.
Price and Value Proposition
The AMD AM4 Backplate is available for $6.99, making it an economical choice for users needing a reliable mounting solution. In comparison, the Thermalright AXP90 X47 is priced at $33.99, which is about 487% more expensive than the backplate. While the backplate offers great value for specific needs, the cooler provides a comprehensive solution with active cooling capabilities suitable for high-performance systems. Therefore, the choice between these products hinges on the user's specific requirements—whether they need a simple mounting solution or a full-fledged CPU cooler.
Which should you buy?
Choosing between the AMD AM4 Backplate and the Thermalright AXP90 X47 ultimately depends on your needs. If you are looking for an affordable solution to secure your heatsink on an AM4 motherboard, the AMD AM4 Backplate at $6.99 is a sound choice. However, if you're in need of an efficient cooling solution that supports multiple CPU sockets, the Thermalright AXP90 X47 offers superior performance, albeit at a higher price of $33.99. Consider your system's cooling requirements, compatibility, and budget to make the best decision for your build.
