Overview of Thermalright AM5 Secure Frame Black AM5 CPU Holder and Thermalright Assassin King 120 SE ARGB CPU Air Cooler
The Thermalright AM5 Secure Frame Black AM5 CPU Holder is priced at C$14.90, while the Thermalright Assassin King 120 SE ARGB CPU Air Cooler retails for C$24.59. These products cater to different needs within the CPU cooling realm, with the former focusing on CPU support and stabilization, and the latter on active cooling.
The AM5 Secure Frame serves primarily to prevent CPU bending, particularly for AM5 socket motherboards, while the Assassin King 120 SE offers robust cooling capabilities with its fan and heatsink design. Both products are manufactured by Thermalright, a brand known for its focus on computer accessories, contributing to their reliability in performance.
Design and Build Quality
In terms of design and build quality, the Thermalright AM5 Secure Frame is crafted from all-aluminum alloy, featuring a black anodized finish that enhances its durability. Weighing only 55g, it is designed to provide non-marking installation with even pressure edges, ensuring that it won’t wear out over time. The frame’s insulated foot pads are specifically designed to prevent thermal conductive silicone from contacting the CPU, thus reducing capacitance and enhancing performance.
Conversely, the Thermalright Assassin King 120 SE boasts a larger structure, measuring 120mm in length, 73mm in width, and 148mm in height. The cooler is built from aluminum and equipped with metal fasteners that support both Intel and AMD platforms, making it versatile for different setups. Its design includes advanced AGHP III technology that mitigates the inverse gravity effect, ensuring consistent cooling performance regardless of orientation.
Cooling Performance
The cooling performance of the Thermalright Assassin King 120 SE far surpasses that of the AM5 Secure Frame, as the latter does not provide active cooling but rather stabilizes the CPU. The Assassin King 120 SE features a PWM fan that operates at 1550 RPM, generating an airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A). This combination ensures that it effectively dissipates heat while keeping the operating environment quiet.
On the other hand, the AM5 Secure Frame does not contribute to cooling but is essential for maintaining the integrity of the CPU under heavy loads. It supports the weight of CPU coolers and prevents bending, which indirectly aids in maintaining optimal cooling performance by ensuring that the CPU is properly seated. However, it lacks any active cooling features, which is crucial for high-performance builds.
Installation Process
The installation process for the Thermalright AM5 Secure Frame is straightforward, as it comes with an L-shaped screwdriver and includes a tube of TF7 thermal grease. The design allows for easy, one-step installation, ensuring that users can set it up without hassle. It is specifically designed for AM5 CPU motherboard slots, making it an ideal choice for users with compatible setups.
In contrast, the Thermalright Assassin King 120 SE requires a bit more effort due to its larger size and more complex installation involving mounting plates or fasteners. However, it comes with a detailed installation guide that helps users effectively install the cooler onto various CPU sockets, including AM4 and AM5. This level of compatibility is a significant advantage for users who may upgrade their systems in the future.
Compatibility
The compatibility of the Thermalright AM5 Secure Frame is limited to the AM5 CPU slots on motherboards equipped with the X670 and B650 chipsets. This specialized focus makes it an excellent choice for users specifically building or upgrading systems with AMD’s latest architecture.
On the other hand, the Thermalright Assassin King 120 SE offers broader compatibility, supporting not only AM5 but also multiple Intel socket types, including 115X, 1200, and 1700. This versatility allows it to cater to a wider audience and various builds, making it a more flexible option for users looking to invest in a cooling solution that will last through several upgrades.
Brand Reputation and Market Position
Thermalright has established itself as a reputable brand in the CPU cooling market, with over 20 years of experience. The company is known for its commitment to research and development, producing a diverse range of products that meet the needs of gamers and PC builders alike.
Both the AM5 Secure Frame and the Assassin King 120 SE are representative of Thermalright's dedication to quality and performance. The reputation of the brand adds value to both products, ensuring users are making a reliable choice when investing in their cooling solutions.
Price Point
The price point is a significant differentiator between the two products. The Thermalright AM5 Secure Frame is priced at C$14.90, making it an affordable option for users seeking to support their CPU without breaking the bank. This low-cost solution is ideal for budget-minded builders who may be looking to enhance their system's stability without investing heavily.
In contrast, the Thermalright Assassin King 120 SE is priced at C$24.59, reflecting its advanced features and active cooling capabilities. While it is more expensive, the added benefits of better cooling performance and compatibility with multiple CPU sockets justify the higher price for users requiring more robust cooling solutions.
Which should you buy?
When deciding between the Thermalright AM5 Secure Frame Black AM5 CPU Holder and the Thermalright Assassin King 120 SE ARGB CPU Air Cooler, it largely depends on your specific needs. If you require a solution focused on CPU support and stabilization for an AM5 setup, the AM5 Secure Frame is a cost-effective choice at C$14.90.
