Overview of the Products
In this comparison, we will explore two CPU cooler options: the DGZZI AM4 Backplane Back Durable CPU Heatsink Bracket and the Thermalright Assassin X120 Refined SE CPU Air Cooler. The DGZZI model is priced at $7.99, while the Thermalright cooler comes in at $17.90. This represents a price difference of about 125%, with the DGZZI being the more budget-friendly option. However, their purposes and functionalities differ significantly, which is crucial to consider.
Design and Build Quality
The DGZZI AM4 Backplane is designed specifically for AMD Socket AM4 motherboards, featuring a combination of copper and plastic materials. This design ensures good heat dissipation and prevents deformation over time. It’s a straightforward mounting bracket, making it ideal for users who simply need a replacement part for their CPU fan setup. In contrast, the Thermalright Assassin X120 boasts a more complex design with an aluminum heatsink cover and four heat pipes that apply AGHP technology. This design focuses on maximizing cooling efficiency and features a PWM fan that enhances airflow while minimizing noise levels to 25.6 dB(A).
Cooling Performance
When it comes to cooling performance, the Thermalright Assassin X120 stands out as a more advanced option. With its four heat pipes and a PWM fan that can reach an air flow of 66.17 CFM, it is engineered to cool CPUs effectively under load. The DGZZI bracket, however, serves a different function. It is not an air cooler in itself but a mounting solution that allows for better cooling by securing a CPU fan in place. Thus, if you are looking for substantial cooling performance, the Thermalright is the clear winner.
Compatibility
The DGZZI AM4 Backplane is specifically designed for AMD's AM4 Socket, fitting well with motherboards like the B350, X370, A320, and X470 chipsets. Its compatibility is straightforward, making it a practical choice for users needing a replacement mount. On the other hand, the Thermalright Assassin X120 offers broader compatibility, supporting not only AMD AM4 and AM5 sockets but also various Intel sockets, including LGA 1150 through 1700. This versatility makes the Thermalright a better option for those who might switch platforms or have mixed systems.
Installation Process
The installation process for the DGZZI AM4 Backplane seems relatively simple, as it involves replacing an existing mounting bracket. Its installation hole distance is 90x54mm, which is specific but clear for users familiar with their motherboard layout. In comparison, the Thermalright Assassin X120 comes with multiple mounting plates and fasteners for different CPU socket types. While this may add complexity to the installation, it ensures a secure fit across various platforms, appealing to more advanced users.
Brand Reputation
The DGZZI brand is less well-known compared to Thermalright, which has over 20 years of experience in the computer accessories market. Thermalright has established a reputation for quality and reliability, particularly in the realm of cooling solutions. Their products are often recommended in forums and tech reviews, giving them a solid standing among users looking for dependable performance. The DGZZI, while functional, may not carry the same weight in brand recognition, which could influence purchasing decisions.
Price Comparison
The DGZZI AM4 Backplane is priced at $7.99, making it an economical choice for users needing a basic mounting solution. In contrast, the Thermalright Assassin X120 at $17.90 is about 125% more expensive. This price difference is significant, especially for budget-conscious consumers looking for straightforward solutions. However, the higher cost of the Thermalright is justified by its advanced cooling technology and broader compatibility, which may be worth the investment for performance-oriented users.
Which should you buy?
Ultimately, the choice between the DGZZI AM4 Backplane and the Thermalright Assassin X120 depends on your specific needs. If you are looking for a simple and cost-effective replacement for an AMD AM4 CPU fan bracket, the DGZZI is an excellent option at $7.99. However, if you require superior cooling performance and broader compatibility with both AMD and Intel sockets, the Thermalright Assassin X120 at $17.90 is worth the extra expense. Thus, for users focused on performance and longevity, the Thermalright is the clear recommendation, while the DGZZI serves well for practical, budget-friendly replacements.
