Price Comparison

When it comes to pricing, the AMD AM4 Backplate is significantly more affordable at C$5.85, compared to the Thermalright Assassin X 120 SE, which is priced at C$24.29. The stark difference in cost highlights that the AMD AM4 Backplate is a budget-friendly option for those specifically looking to mount heatsinks on AM4 motherboards. In contrast, the Thermalright Assassin X 120 SE is positioned as a premium cooling solution, suitable for users who require enhanced cooling performance and are willing to invest more for it. If price is a primary consideration, the AMD AM4 Backplate clearly stands out.

Design and Build Quality

The AMD AM4 Backplate features a precision-crafted design tailored for the AM4 platform, ensuring a secure hold for heatsinks. Its construction incorporates copper and high-quality ABS plastic, aimed at maximising heat dissipation. This design is specifically engineered to meet the thermal requirements of AM4 socket processors, promoting efficient thermal management. On the other hand, the Thermalright Assassin X 120 SE boasts a more robust build, featuring an aluminium heat sink and a weight of 0.645 kg. It employs advanced AGHP technology with four 6mm heat pipes, which enhances cooling performance by addressing inverse gravity effects. This makes the Thermalright a more versatile and durable option for users looking for reliable, long-term cooling solutions.

Cooling Performance

In terms of cooling performance, the Thermalright Assassin X 120 SE is built for efficiency, with its PWM fan capable of delivering an airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A). This makes it suitable for both effective cooling and quiet operation, ideal for gamers and professionals alike. In contrast, the AMD AM4 Backplate, while enhancing heat dissipation, does not serve as a cooling fan itself, and thus lacks the active cooling capabilities offered by the Thermalright. Users requiring superior cooling performance will find the Thermalright's specifications more appealing, particularly for demanding tasks or overclocking scenarios.

Compatibility

The AMD AM4 Backplate is exclusively designed for AM4 socket motherboards, making it a very specific solution for those systems. It ensures stable mounting pressure for optimal heat transfer, but its limited compatibility means it won't serve users with other CPU types. The Thermalright Assassin X 120 SE, however, supports a broader range of sockets, including Intel's 115X/1200/1700 series and AMD's AM4. This versatility offers users greater flexibility, making the Thermalright a more attractive option for those who may upgrade their systems in the future or use multiple platforms.

Installation Process

The installation process for the AMD AM4 Backplate is straightforward, given its design tailored specifically for the AM4 platform. It is intended for users who might not require extensive cooling solutions or who are replacing existing backplates. However, the Thermalright Assassin X 120 SE comes with metal fasteners compatible with both Intel and AMD platforms, which may complicate installation slightly for those unfamiliar with CPU coolers. That said, its design allows for a secure and efficient installation, ensuring that users benefit from optimal cooling right from the start. For those comfortable with installation, the Thermalright may provide greater long-term benefits.

Brand Reputation

In terms of brand reputation, Thermalright has over 20 years of experience in the computer accessories market, gaining popularity and influence within the community. Their commitment to research and development has established them as a trusted name in CPU cooling solutions. While HuGuWdy, the manufacturer of the AMD AM4 Backplate, provides a solid product, it lacks the same level of brand recognition and long-standing reputation as Thermalright. Users often prefer products from established brands for the assurance of quality and reliability, which may sway some buyers toward the Thermalright option.

Customer Support and Information

The AMD AM4 Backplate offers detailed product information and images, which can assist customers in understanding the product better and saving time during the purchasing process. The brand also emphasizes being available for customer queries, enhancing user confidence in their support. Conversely, while the Thermalright Assassin X 120 SE is supported by an established brand, specific customer support details are not outlined in the product information provided. Users may find the proactive approach of HuGuWdy appealing, especially if they value detailed product guidance.

Which should you buy?

Choosing between the AMD AM4 Backplate and the Thermalright Assassin X 120 SE comes down to your specific needs and budget. If you are looking for an economical solution solely for mounting heatsinks on AM4 motherboards, the AMD AM4 Backplate at C$5.85 is a clear choice. However, if you require a high-performance CPU cooler that supports multiple sockets and offers advanced cooling capabilities, the Thermalright Assassin X 120 SE at C$24.29 is the better investment. Ultimately, your decision should be guided by whether you prioritise cost or performance in your CPU cooling solution.
