Overview of the Products
In the world of CPU coolers, the DGZZI AM4 Backplane and the Thermalright AXP90 X47 Full Low Profile CPU Cooler offer distinct features for different needs. The DGZZI is a budget-friendly mounting bracket priced at $7.99, while the Thermalright AXP90 X47 comes at a higher price of $33.99, boasting advanced cooling capabilities. Your choice will depend largely on your specific cooling needs and budget constraints.
Design and Build Quality
The DGZZI AM4 Backplane is designed specifically for AMD Socket AM4 motherboards, featuring a combination of copper and plastic materials. It ensures good heat dissipation and prevents deformation over time. On the other hand, the Thermalright AXP90 X47 showcases a low-profile design, with a height of only 47mm. Its pure copper base and four heat pipes enhance heat transfer efficiency. The Thermalright's plating anti-oxidation protective layer adds to its durability, making it a robust choice for those needing a reliable cooler.
Cooling Performance
When it comes to cooling performance, the Thermalright AXP90 X47 outshines the DGZZI AM4 Backplane. The Thermalright features a 92mm PWM fan that operates at a noise level of 22.4 dB(A) while delivering an airflow of 42.58 CFM. This design allows for excellent heat transfer from the CPU, making it suitable for high-performance computing. In contrast, the DGZZI is primarily a mounting bracket that does not include a fan, limiting its cooling capabilities significantly.
Compatibility
In terms of compatibility, the DGZZI AM4 Backplane is tailored exclusively for AMD Socket AM4 motherboards, making it a straightforward choice for users with that specific setup. Conversely, the Thermalright AXP90 X47 accommodates both Intel and AMD systems, supporting a variety of sockets including Intel LGA 1150/1151/1155/1156/1200/1700 and AMD AM4. This versatility allows users of the Thermalright cooler to integrate it into a broader range of builds.
Installation Process
The installation process for both products differs considerably due to their designs. The DGZZI AM4 Backplane features a straightforward installation with a mounting hole spacing of 90x54mm, making it easy to set up for those familiar with CPU coolers. However, it doesn't include a CPU fan, which means users must purchase one separately. The Thermalright AXP90 X47, while more complex due to its integrated cooling solution, offers an all-in-one package that simplifies the process for users looking to upgrade their cooling system.
Price Comparison
The DGZZI AM4 Backplane is priced at $7.99, making it about 76% cheaper than the Thermalright AXP90 X47, which retails for $33.99. This significant price difference makes the DGZZI an appealing option for budget-conscious consumers who may only need a mounting bracket. However, the additional investment in the Thermalright cooler can be justified by its superior cooling performance and compatibility with various CPU sockets.
User Experience and Feedback
While there is limited data on user feedback for both products, the Thermalright AXP90 X47 is likely to garner more positive reviews due to its advanced cooling capabilities and versatility. The DGZZI AM4 Backplane may meet the needs of users looking for a simple replacement part, but it lacks the features that typically earn high praise in user reviews. Customers seeking reliable cooling solutions often prioritize performance, which the Thermalright cooler offers.
Which should you buy?
Choosing between the DGZZI AM4 Backplane and the Thermalright AXP90 X47 depends on your specific needs and budget. If you are looking for an affordable mounting solution specifically for AMD Socket AM4, the DGZZI is a practical choice. However, for those needing superior cooling performance and compatibility across multiple socket types, the Thermalright AXP90 X47 is worth the investment despite its higher price. Ultimately, weigh your requirements against the features offered by each product to make an informed decision.
