Overview of the Products
In this comparison, we will take a look at the DGZZI AM4 Backplane and the Thermalright Peerless Assassin 120 Black CPU Air Cooler. The DGZZI AM4 Backplane is priced at $7.99, while the Thermalright Peerless Assassin 120 Black is significantly more expensive at $38.90, making it about 387% higher in price. Both products cater to AMD users but serve different purposes within the realm of CPU cooling solutions.
Design and Build Quality
The DGZZI AM4 Backplane features a combination of copper and ABS plastic, which ensures good heat dissipation and long service life. Specifically designed for AMD Socket AM4 motherboards, it offers a mounting hole spacing of 90x54mm. In contrast, the Thermalright Peerless Assassin 120 Black boasts an aluminum heatsink cover and a double tower design that enhances cooling efficiency. With a weight of 1.02 kg, it is a robust option for serious gamers and overclockers. The latter's advanced design suggests a more professional build quality, aimed at maximizing performance under heavy workloads.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 120 Black stands out. It is engineered with six heat pipes and dual PWM fans that can deliver an airflow of up to 66.17 CFM, operating at a maximum noise level of 25.6 dB(A). The cooling solution is designed for TDPs of up to 245W, making it suitable for high-performance CPUs. On the other hand, the DGZZI AM4 Backplane primarily functions as a mounting solution and does not provide active cooling features. Therefore, if you're seeking superior thermal management, the Thermalright cooler is clearly the better choice.
Compatibility
The DGZZI AM4 Backplane is specifically designed for AMD Socket AM4 CPUs and is compatible with various chipsets like B350, X370, A320, and X470. It provides a simple yet effective solution for mounting CPU fans. In comparison, the Thermalright Peerless Assassin 120 Black supports a wider range of sockets, including Intel LGA 1200, 1700, and several AMD sockets such as AM4 and AM5. This versatility makes the Thermalright cooler a more adaptable option for users who may switch platforms in the future.
Installation Process
The installation process for the DGZZI AM4 Backplane is straightforward, as it involves replacing existing mounting hardware for your motherboard. The bracket is designed to fit securely with a pin hole that corresponds to the motherboard, making it practical for DIY builds. Conversely, the Thermalright Peerless Assassin 120 Black may require a more involved installation due to its dual tower design and multiple components. While both products aim to simplify installation, the DGZZI option is decidedly user-friendly and ideal for those who may not have extensive experience with CPU cooling setups.
Price Comparison
The price difference between these two products is significant. The DGZZI AM4 Backplane is available for $7.99, while the Thermalright Peerless Assassin 120 Black is priced at $38.90. This means that the DGZZI is about 80% cheaper than the Thermalright cooler. While the lower price point makes the DGZZI attractive for budget-conscious consumers, it is essential to consider what you are getting for that price. The Thermalright cooler, while more expensive, offers advanced cooling capabilities and features that may justify the investment for power users.
User Experience and Reviews
Although detailed user reviews are not provided, one can infer from the specifications that the DGZZI AM4 Backplane is likely to meet the expectations of average users looking for a simple and effective mounting solution. However, for enthusiasts and gamers, the Thermalright Peerless Assassin 120 Black is engineered to deliver performance that aligns with higher expectations. Its advanced cooling technology and build quality suggest it would perform admirably during intense computing tasks, making it a more appealing choice for users who demand top-tier performance.
Which should you buy?
The choice between the DGZZI AM4 Backplane and the Thermalright Peerless Assassin 120 Black ultimately depends on your specific needs. If you are looking for an economical solution for mounting a CPU fan and have a standard use case, the DGZZI option is more than adequate. However, if you require superior cooling performance for gaming, overclocking, or demanding applications, the Thermalright cooler, despite its higher price, will likely provide significant benefits in terms of thermal management and reliability.
