Overview of the Products

In this comparison, we are examining the Thermalright Assassin X 90 SE V2 CPU Cooler and the Thermalright AM5 Secure Frame Black AM5 CPU Holder. The Assassin X 90 SE V2 is priced at C$24.90, while the AM5 Secure Frame is available for C$14.90. These products cater to different needs in CPU cooling and support, making it essential to understand their unique features and applications.

Product Design and Build Quality

The Thermalright Assassin X 90 SE V2 boasts a robust design with a height of 118mm and dimensions of 94(L)x77(W)x118(H)mm. It features an aluminum heat sink and a PWM fan that delivers a maximum air flow of 32.77 CFM. In contrast, the AM5 Secure Frame is designed specifically for AMD’s AM5 CPUs, measuring 70(L) x 54(W) x 6(H)mm. Made from all-aluminum alloy with an anodized finish, it is engineered for durability and aesthetic appeal. The build quality of both products reflects Thermalright's commitment to high standards, but they serve different purposes within a CPU setup.

Cooling Performance

The Thermalright Assassin X 90 SE V2 is a dedicated CPU cooler that utilises AGHP technology with a 4x6mm heatpipe, ensuring effective heat dissipation. It can operate at a fan speed of 2200 RPM, maintaining a noise level of ≤23.85 dB(A), which is relatively quiet for a cooler. On the other hand, the AM5 Secure Frame does not provide cooling directly; instead, it supports the CPU and cooler, preventing bending under pressure. Therefore, while the Assassin X 90 SE V2 excels in cooling performance, the AM5 Secure Frame is an essential accessory to maintain structural integrity.

Compatibility and Installation

The Assassin X 90 SE V2 supports a wide range of CPU slots, including Intel’s 1150 to 1200 and AMD’s AM4 and AM5, making it versatile for various setups. It comes with the necessary mounting plates and instructions to facilitate installation. The AM5 Secure Frame is exclusively designed for AMD's AM5 CPUs and includes an L-shaped screwdriver for easy installation. Its compatibility is limited to AM5 motherboards, specifically for the X670 and B650 series chipsets. This focused compatibility may appeal to users with specific needs, while the Assassin X 90 SE V2 offers broader support.

Thermal Management Features

The Assassin X 90 SE V2 incorporates advanced thermal management features such as an industrial-grade PWM fan and S-FDB bearings, which ensure long service life and efficient cooling. The fan's design contributes to achieving a maximum air flow of 32.77 CFM, which is crucial during high-performance tasks. Conversely, the AM5 Secure Frame enhances thermal management by ensuring an even pressure distribution on the CPU, reducing the risk of bending. It also includes TF7 silicone grease with a thermal conductivity of 12.8 W/M.K, which can further improve cooling performance when paired with a cooler. Thus, while the Assassin X 90 SE V2 provides direct cooling, the AM5 Secure Frame complements this with structural support.

User Experience

Users of the Thermalright Assassin X 90 SE V2 often appreciate its balance between performance and noise levels, making it suitable for both gaming and professional use. The product's design, which incorporates a high-speed fan, allows for effective cooling without excessive noise. The AM5 Secure Frame, on the other hand, is noted for its straightforward installation process and precise fit, which reduces the risk of damage during cooler installation. While user experiences may vary based on individual setups, both products are generally well-received for their respective functionalities.

Brand Reputation

Thermalright has a solid reputation in the cooling market, backed by over 20 years of experience in developing computer accessories. The brand's focus on R&D ensures that both the Assassin X 90 SE V2 and the AM5 Secure Frame reflect high manufacturing standards and innovative technology. This reputation adds an extra layer of confidence for consumers when choosing either product, as they can expect quality and reliability from Thermalright.

Price Consideration

The Thermalright Assassin X 90 SE V2 is priced at C$24.90, making it a budget-friendly option for a dedicated CPU cooler. The AM5 Secure Frame is even more affordable at C$14.90, providing a cost-effective solution for enhancing CPU support and preventing bending. While both products are reasonably priced, the choice may ultimately depend on the user's specific needs—whether they require a cooling solution or additional support for their AM5 CPU.

Which should you buy?

Choosing between the Thermalright Assassin X 90 SE V2 CPU Cooler and the Thermalright AM5 Secure Frame Black AM5 CPU Holder hinges on your specific requirements. If you need an effective cooling solution for a range of CPUs, the Assassin X 90 SE V2 is the superior choice, offering excellent thermal management and compatibility. However, if you are focused on supporting an AM5 CPU to prevent bending while using a cooler, the AM5 Secure Frame is an essential addition. Ultimately, for optimal performance, consider pairing both products to achieve the best results in your CPU setup.
