Overview of the Products

In this comparison, we examine the AMD AM4 Backplate and the Thermalright Assassin X 120R SE V2 CPU Air Cooler. The AMD AM4 Backplate is priced at C$5.85, while the Thermalright cooler retails for C$23.59. Understanding their primary functions and features will help potential buyers determine which product is more suitable for their needs.

The AMD AM4 Backplate is designed specifically for the AM4 platform, providing a secure hold for heatsinks. It focuses on optimizing cooling performance for AMD CPUs. In contrast, the Thermalright Assassin X 120R SE V2 is a comprehensive air cooler that incorporates advanced technologies and noise-reduction features, making it suitable for a wider range of CPUs, including both AMD and Intel sockets.

Design and Build Quality

When it comes to design and build quality, both products serve their unique purposes. The AMD AM4 Backplate features a precision-crafted design tailored for AM4 motherboards, ensuring an exact fit and stable mounting pressure. Its construction includes high-quality ABS plastic and copper, enhancing heat dissipation.

On the other hand, the Thermalright Assassin X 120R SE V2 boasts a more complex build. It employs 4×6mm heat pipes and S-FDB bearings for longer service life, and its overall dimensions are tailored to fit medium-sized computer cases without obstructing memory installation. This contrasts with the simple yet effective function of the AMD backplate, which is purely a mounting solution.

Cooling Performance

Cooling performance is a critical factor for any CPU component. The AMD AM4 Backplate focuses on maximizing heat dissipation for AMD CPUs, ensuring stable performance under load. However, it does not include a fan or cooling mechanism itself; it's merely a mounting solution.

In comparison, the Thermalright Assassin X 120R SE V2 offers a maximum airflow of 66.17 CFM, significantly enhancing heat management for various CPU models. With a noise level capped at 25.6 dB(A), it allows for efficient cooling while maintaining a quiet environment. This makes the Thermalright cooler a superior choice for users looking for effective thermal management.

Compatibility

Compatibility is essential when choosing a cooling solution. The AMD AM4 Backplate is exclusively designed for the AM4 socket, making it a dedicated option for AMD users. It is specifically crafted to ensure a perfect fit, providing optimized performance for AMD processors.

Conversely, the Thermalright Assassin X 120R SE V2 supports a wider range of CPU sockets, including both AMD (AM4 and AM5) and several Intel sockets (LGA1150/1151/1155/1156/1200/1700). This broader compatibility makes it a versatile choice for users who may upgrade their systems or switch between AMD and Intel processors in the future.

Noise Levels

Noise levels can significantly impact the user experience, especially in gaming or professional environments. The AMD AM4 Backplate, being a passive mounting solution, does not generate any noise, making it an ideal choice for those prioritizing silence.

In contrast, the Thermalright Assassin X 120R SE V2 operates at a maximum noise level of 25.6 dB(A). While not excessively loud, it is an important consideration for users who are sensitive to noise. Its PWM fan technology allows for efficient cooling with minimal sound, balancing performance and quiet operation effectively.

Price Point

Price is always a crucial factor when making a purchasing decision. The AMD AM4 Backplate is priced at C$5.85, making it an economical choice for those specifically needing a mounting bracket for AM4 motherboards. It offers excellent value for users who already have a cooling solution in place.

On the other hand, the Thermalright Assassin X 120R SE V2 is priced at C$23.59. While it is more expensive, it offers a complete cooling solution that includes fan technology and broader compatibility. For users looking for a comprehensive cooling solution rather than just a mounting bracket, the additional cost may be justified.

User Experience and Installation

User experience and ease of installation are important factors to consider. The AMD AM4 Backplate is designed for straightforward installation, aimed at users who need a reliable mounting solution for their AM4 CPUs. The detailed product images and descriptions provided by the manufacturer also help users understand installation requirements.

In contrast, the Thermalright Assassin X 120R SE V2 comes with detailed installation instructions and videos, ensuring that users can install the cooler efficiently. Its user-friendly design allows for easy adjustments, making it suitable for both novice and experienced builders. The comprehensive nature of this cooler enhances the overall user experience compared to the simpler backplate.

Which should you buy?

Choosing between the AMD AM4 Backplate and the Thermalright Assassin X 120R SE V2 largely depends on your specific needs. If you require a dedicated mounting solution for an AMD AM4 motherboard and already have a cooling fan, the AMD AM4 Backplate at C$5.85 is a cost-effective choice. However, if you are looking for a complete cooling solution that offers compatibility with both AMD and Intel processors, superior cooling performance, and quieter operation, the Thermalright Assassin X 120R SE V2, priced at C$23.59, would be the better investment.
