DGZZI AM4 Backplane Back Durable CPU Heatsink vs Thermalright Assassin X 120R SE V2 CPU Cooler, 4×
Updated August 2026 — full head-to-head comparison.
Overview of the Products
In the realm of CPU coolers, the DGZZI AM4 Backplane and the Thermalright Assassin X 120R SE V2 stand out for different reasons. The DGZZI AM4 Backplane is primarily a mounting bracket designed for AMD Socket AM4 motherboards, while the Thermalright Assassin X offers comprehensive cooling capabilities with a full heatsink and fan system. Understanding these differences is crucial for selecting the right product for your needs.
Design and Build Quality
The DGZZI AM4 Backplane features a simple yet effective design focused on functionality. Made from copper and ABS plastic, it provides good heat dissipation and durability, ensuring that your CPU can operate efficiently. It is specifically designed for AMD Socket AM4 motherboards, featuring a mounting hole spacing of 90x54mm. On the other hand, the Thermalright Assassin X 120R SE V2 boasts a more complex structure with multiple components. It includes a pure copper base and four heat pipes, combined with a 120mm PWM fan that operates at a speed of 1550 RPM. This cooler’s robust design not only enhances cooling performance but also adds a layer of aesthetic appeal due to its RGB lighting.
Cooling Performance
Cooling performance is a significant differentiator between the two products. The DGZZI AM4 Backplane serves as a mounting solution and does not provide active cooling, making it suitable primarily for setups where an existing cooling system is in place. Conversely, the Thermalright Assassin X 120R SE V2 excels in this category, with its efficient 120mm PWM fan capable of producing airflow of 66.17 CFM while maintaining a noise level below 25.6 dB(A). This means that the Thermalright cooler is designed to keep your system cool even during intensive tasks, making it a better option for gamers and heavy users.
Compatibility
When it comes to compatibility, the DGZZI AM4 Backplane is tailored specifically for AMD Socket AM4 CPUs, making it a limited choice for users with different CPU sockets. It is an ideal product for users who need a replacement bracket for their existing cooling solutions. In contrast, the Thermalright Assassin X 120R SE V2 offers broader compatibility, supporting both AMD AM4/AM5 and various Intel sockets including LGA1150 and LGA1700. This versatility makes the Thermalright cooler a more adaptable choice for users who may switch platforms in the future.
Installation Process
The installation process varies significantly between the two products. The DGZZI AM4 Backplane requires a straightforward mounting procedure, as it is simply a bracket that attaches to the motherboard. This can be beneficial for users who are looking for a quick and easy setup. On the other hand, the Thermalright Assassin X 120R SE V2 may involve a more complex installation due to its multiple components and the need to apply thermal paste. However, the manufacturer provides mounting plates and fasteners for different platforms, which can simplify the process for users who follow the provided instructions or installation videos.
Price Comparison
In terms of pricing, the DGZZI AM4 Backplane is priced at $7.99, making it a budget-friendly option for users in need of a replacement mounting bracket. In contrast, the Thermalright Assassin X 120R SE V2 is priced at $16.59, representing a difference of about 17%. While the Thermalright cooler is more expensive, it offers significantly enhanced cooling performance and versatility, which may justify the higher price for many users.
Target Audience
The target audience for these products is quite distinct. The DGZZI AM4 Backplane is aimed at users with existing cooling solutions who need a reliable mounting bracket for their AMD Socket AM4 CPUs. It's perfect for budget-conscious individuals who prioritize functionality over performance. On the other hand, the Thermalright Assassin X 120R SE V2 is designed for gamers, content creators, and PC enthusiasts who demand high-performance cooling solutions. Its enhanced cooling capabilities and compatibility with multiple CPU sockets make it an ideal choice for those looking to maximize their system's performance.
Which should you buy?
Ultimately, the choice between the DGZZI AM4 Backplane and the Thermalright Assassin X 120R SE V2 depends on your specific needs. If you require a basic mounting solution for your AMD Socket AM4 motherboard and are on a tight budget, the DGZZI AM4 Backplane is a solid option. However, if you are looking for a comprehensive cooling solution that offers exceptional performance and compatibility, the Thermalright Assassin X 120R SE V2 is the superior choice despite its higher price. Consider your system requirements and budget before making a decision.
