Product Overview
The AMD AM4 Backplate and the Thermalright Assassin King 120 SE White ARGB CPU Air Cooler are two distinct products designed for different aspects of CPU cooling. The backplate, priced at $6.99, is a simple mounting solution specifically for AMD AM4 sockets, while the cooler is a more comprehensive air cooling solution priced at $19.82. This price difference of about 184% highlights the varying complexities and functionalities between the two products.
The AMD AM4 Backplate is engineered to ensure a secure hold for heatsinks on AMD motherboards, optimizing heat dissipation with a design that includes copper and high-quality ABS plastic. Conversely, the Thermalright Assassin King offers advanced cooling technology with five heat pipes and an ARGB PWM fan, catering to users looking for enhanced cooling performance and aesthetics.
Design and Build Quality
In terms of design, the AMD AM4 Backplate is precision-crafted to fit the AM4 socket perfectly, ensuring stability and optimal heat transfer. Its materials focus on durability and efficiency, designed specifically for AMD's requirements. On the other hand, the Thermalright Assassin King boasts a more complex structure with a 120mm aluminum radiator and five heat pipes that utilize AGHP technology to enhance cooling efficiency.
The choice of materials in the Assassin King, including industrial-grade PBT and PC, contributes to its robustness, making it suitable for various setups. This difference in design complexity signifies that while the backplate is straightforward and utilitarian, the cooler is built for performance and longevity.
Cooling Performance
The cooling performance of the Thermalright Assassin King is significantly superior to that of the AMD AM4 Backplate. The Assassin King features five heat pipes and a PWM fan that can achieve a maximum airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A). This performance is aimed at users who push their CPUs to high limits and require efficient cooling solutions.
In contrast, the AMD AM4 Backplate is not a cooling solution by itself but rather a necessary component for securing a heatsink. While it enhances cooling indirectly by ensuring proper mounting, it does not provide active cooling features. Thus, users looking for direct cooling solutions should consider the Thermalright Assassin King as their primary option.
Compatibility
The AMD AM4 Backplate is specifically designed for AMD AM4 platforms, making it a perfect fit for users with compatible motherboards. Its simplicity lies in its targeted use, ensuring that it meets the specific requirements of AM4 socket CPUs.
In contrast, the Thermalright Assassin King offers broader compatibility, supporting not only AMD AM4 sockets but also Intel LGA1700, 1150, 1151, 1200, and 1851 sockets. This wide compatibility makes it a versatile choice for users with different CPU brands and socket types. Therefore, if you are building or upgrading a system with mixed components, the Assassin King is the clear winner in this category.
Price Comparison
The price difference between the two products is substantial, with the AMD AM4 Backplate retailing at $6.99 and the Thermalright Assassin King priced at $19.82. This translates to a price difference of approximately $12.83, making the cooler about 184% more expensive than the backplate.
While the backplate offers an economical option for those solely needing a mounting solution, the cooler's higher price reflects its advanced features and capabilities. Consumers must weigh their options based on their cooling needs and budget constraints, as the backplate serves a specific purpose, whereas the cooler provides comprehensive performance enhancements.
User Experience
Customer feedback for the AMD AM4 Backplate is generally positive, with users appreciating its straightforward installation and effective mounting capabilities for heatsinks. The detailed product information provided by the manufacturer assists users in understanding the product better, thereby enhancing the overall user experience.
On the other hand, the Thermalright Assassin King has garnered attention for its efficient cooling performance and aesthetic appeal due to the ARGB lighting. Users value the combination of high performance and low noise, which is critical for gaming and intensive computational tasks. Thus, while both products have their strengths, the Assassin King may provide a more fulfilling experience for users seeking advanced functionality.
Brand Reputation
HuGuWdy, the brand behind the AMD AM4 Backplate, is less known compared to Thermalright, which boasts over 20 years of experience in the market. Thermalright has established itself as a reputable brand in the CPU cooling sector, known for innovative designs and effective products. This brand recognition can influence purchasing decisions, especially for users who prioritize reliability and proven performance.
The established reputation of Thermalright may also contribute to the perceived value of the Assassin King as a premium product. Buyers often feel more confident investing in a brand with a known track record, especially when it comes to critical components like CPU coolers.
Which should you buy?
Choosing between the AMD AM4 Backplate and the Thermalright Assassin King 120 SE White ARGB CPU Air Cooler largely depends on your specific needs. If you require a straightforward mounting solution for an AMD AM4 socket, the backplate at $6.99 is an economical choice. However, if you are looking for a robust cooling solution with advanced features, the Thermalright Assassin King is worth the investment at $19.82. Its superior performance, compatibility, and brand reputation make it a compelling option for users aiming for optimal CPU cooling.
