Overview of the Products

In this comparison, we will look at the AMD AM4 Backplate - CPU Heatsink Bracket and the Thermalright Assassin X 90 SE V2 CPU Cooler. The backplate is priced at C$5.85, while the cooler comes in at C$24.90. Each product serves a distinct purpose in enhancing the cooling capabilities of AMD processors, but they cater to different needs depending on the user's setup and requirements.

The AMD AM4 Backplate is a mounting bracket specifically designed for AMD AM4 socket motherboards. Its main function is to provide a secure hold for heatsinks, ensuring optimal cooling performance. In contrast, the Thermalright Assassin X 90 SE V2 is a complete air cooler that offers both enhanced cooling performance and compatibility across various CPU sockets, including AM4 and AM5.

Design and Build Quality

The design and build quality of the AMD AM4 Backplate focuses on precision and durability. Crafted with copper and high-quality ABS plastic, the bracket ensures maximum heat dissipation while providing a secure mounting solution for your heatsink. This thoughtful engineering is aimed specifically at optimizing the cooling efficiency of AMD AM4 processors.

The Thermalright Assassin X 90 SE V2, on the other hand, showcases advanced technology with its AGHP upgraded heatpipe design, which promotes efficient cooling through an innovative heat transfer method. The cooler is built with industrial-grade materials, including aluminum and PBT + PC, ensuring longevity and reliability. Its dimensions measure 94mm x 77mm x 118mm, making it compact yet effective in its cooling performance.

Cooling Performance

When it comes to cooling performance, the AMD AM4 Backplate optimizes the heat transfer between the CPU and the heatsink, which is crucial for stable operation. However, it does not provide active cooling itself, relying on the heatsink it supports to dissipate heat effectively.

Conversely, the Thermalright Assassin X 90 SE V2 offers a more robust cooling solution with a maximum airflow of 32.77 CFM and a fan speed of up to 2200 RPM. This active cooling capability allows it to manage temperatures more effectively during intensive computing tasks. The quieter operation, with a noise level of ≤23.85 dB(A), ensures that users can enjoy a silent computing experience while benefiting from exceptional cooling performance.

Compatibility

The AMD AM4 Backplate is specifically engineered for AMD AM4 socket motherboards, making it a targeted solution for users with compatible setups. Its design guarantees a perfect fit, ensuring stable mounting pressure for optimal thermal management.

In contrast, the Thermalright Assassin X 90 SE V2 boasts broader compatibility, supporting both Intel and AMD sockets, including AM4 and AM5. This level of versatility makes it a more appealing option for users who may switch CPU platforms in the future, as it can adapt to various setups without necessitating additional purchases.

Installation Process

Installation of the AMD AM4 Backplate is straightforward, as it is designed specifically for the AM4 platform. Users can expect a hassle-free setup, although they will need to have a compatible heatsink to complete the cooling solution.

The Thermalright Assassin X 90 SE V2 also emphasizes ease of installation, coming with the necessary mounting plates and instructions to facilitate a smooth setup process. Its design accommodates multiple CPU socket types, which simplifies the installation experience for users with different configurations.

Price Comparison

The AMD AM4 Backplate is priced at C$5.85, making it an economical choice for users looking to enhance their cooling setup without investing heavily. However, it only serves as a bracket and does not include a cooling fan, which means users will need to purchase a compatible heatsink separately.

On the other hand, the Thermalright Assassin X 90 SE V2 is priced at C$24.90. While it is significantly more expensive, this investment includes a complete cooling solution with active fan capabilities, providing a more comprehensive approach to CPU cooling. The additional cost may be justified for users seeking a more effective and versatile cooling system.

Brand Reputation

HuGuWdy, the brand behind the AMD AM4 Backplate, may not be as widely recognized as Thermalright, which has over 20 years of experience in the cooling market. Thermalright has built a solid reputation for producing high-quality cooling solutions and has a strong presence in both domestic and international markets.

This brand distinction could influence consumer confidence, especially for those prioritizing reliability and performance in their cooling solutions. The established track record of Thermalright may appeal more to users looking for proven products.

Which should you buy?

Ultimately, the choice between the AMD AM4 Backplate and the Thermalright Assassin X 90 SE V2 depends on your specific cooling needs and budget. If you are looking for a cost-effective solution solely for mounting purposes on an AM4 motherboard, the AMD AM4 Backplate is a suitable choice at C$5.85. However, if you're seeking a comprehensive cooling solution with active performance and compatibility across various CPU platforms, the Thermalright Assassin X 90 SE V2 is the better investment at C$24.90. Consider your requirements and choose the product that aligns best with your cooling objectives.
