Overview
When comparing the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright ASF-RED AM5 CPU Holder, it's crucial to note that they serve different purposes within the realm of CPU cooling solutions. The Assassin X 120R SE V2 is a comprehensive air cooling solution, while the ASF-RED is a support accessory designed to enhance the stability of AM5 CPUs. The price difference also reflects their respective functionalities, with the air cooler priced at C$23.59 and the CPU holder at C$10.99.
Purpose and Functionality
The primary function of the Thermalright Assassin X 120R SE V2 CPU Air Cooler is to provide efficient cooling to your CPU through its advanced design and features. With a fan speed of 1550 RPM and an airflow of 66.17 CFM, this cooler aims to maintain optimal temperatures while keeping noise levels to a minimum, rated at ≤25.6 dB(A). In contrast, the Thermalright ASF-RED AM5 CPU Holder serves as a stabilising accessory for AM5 CPUs, preventing bending and ensuring even pressure distribution. This dedicated CPU holder supports the weight of the cooler, making it essential for users working with AM5 socket motherboards.
Design and Build Quality
The Thermalright Assassin X 120R SE V2 boasts a sophisticated design, utilising 4×6mm heat pipes and S-FDB bearings for enhanced cooling performance and durability, promising up to 20,000 hours of service life. Its height of 148mm is suitable for medium-sized cases, ensuring compatibility without obstructing memory installations. On the other hand, the Thermalright ASF-RED AM5 CPU Holder is crafted from all-aluminum alloy with a sandblasted finish, providing both durability and aesthetic appeal. Its insulated foot pads reduce capacitance, ensuring a safe installation without damaging the CPU cover.
Installation Process
When it comes to installation, the Thermalright Assassin X 120R SE V2 requires following specific mounting instructions for various CPU socket platforms, including Intel and AMD options. The cooler's setup may involve more steps compared to the ASF-RED CPU Holder, which is designed for simple integration. The ASF-RED comes with an L-shaped screwdriver and includes thermal grease for immediate cooling enhancement, allowing users to install it in one step, making it a user-friendly choice for AM5 motherboard slots.
Performance Capabilities
In terms of cooling performance, the Thermalright Assassin X 120R SE V2 is designed to handle demanding CPU tasks, ensuring efficient heat dissipation through its fan and heat pipe technology. The maximum airflow of 66.17 CFM contributes to its effectiveness in maintaining lower temperatures during intensive operations. Conversely, the Thermalright ASF-RED AM5 CPU Holder does not directly influence cooling performance but enhances the overall stability of the CPU under the weight of the cooler, ensuring that the CPU remains securely positioned.
Compatibility
The Thermalright Assassin X 120R SE V2 is compatible with various Intel and AMD CPU sockets, including LGA1700 and AM5, making it a versatile choice for different builds. This broad compatibility ensures that users can effectively utilise the cooler across multiple systems. In contrast, the Thermalright ASF-RED is specifically designed for AM5 CPUs, supporting motherboards with X670 and B650 chipsets. While it is limited in terms of compatibility, it excels in its dedicated purpose for AM5 installations.
Pricing and Value
The pricing for these products reflects their functionality and target audience. The Thermalright Assassin X 120R SE V2 is priced at C$23.59, which is a reasonable investment for those seeking a reliable air cooling solution. On the other hand, the Thermalright ASF-RED AM5 CPU Holder is priced at C$10.99, making it an affordable accessory for those looking to secure their AM5 CPUs. The value proposition for each product varies, with the cooler providing extensive cooling capabilities while the holder focuses on stability and support.
Which should you buy?
Choosing between the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright ASF-RED AM5 CPU Holder depends on your specific needs. If you're looking for an effective cooling solution to maintain optimal CPU performance, the Assassin X 120R SE V2 is the clear choice with its superior airflow and advanced design.
