Overview of Thermalright Products

When comparing the Thermalright ASF-RED AM5 CPU Holder and the Thermalright Assassin X 120 SE CPU Air Cooler, we see two distinct products catering to different needs in CPU cooling. The ASF-RED AM5 is priced at C$10.99, while the Assassin X 120 SE is more robust and comes in at C$25.59. This price difference reflects the different functionalities they offer—one is a holder designed to prevent CPU bending, while the other is a full air cooler aimed at enhancing thermal management.

Design and Build Quality

The design and build quality of each product vary significantly. The ASF-RED AM5 CPU Holder features an all-aluminum anodized sandblasting process, ensuring durability and resistance to scratches. It has a compact size of 70 mm by 54 mm, making it unobtrusive while effectively supporting the CPU. In contrast, the Assassin X 120 SE boasts a larger footprint, measuring 125 mm by 71 mm and standing 148 mm tall. This larger design accommodates its advanced cooling capabilities, utilising aluminum heat sinks and a PWM fan that operates up to 1550 RPM. The build quality of the Assassin X is also enhanced by metal fasteners compatible with both Intel and AMD platforms.

Cooling Performance

In terms of cooling performance, the Thermalright Assassin X 120 SE is designed for significant heat dissipation. It supports a thermal design power (TDP) of between 125 to 225 watts, making it suitable for more demanding CPUs. The presence of four 6mm heat pipes using AGHP technology enhances its efficiency by mitigating the inverse gravity effect. Meanwhile, the ASF-RED AM5 CPU Holder does not provide cooling capability itself but supports the CPU to prevent bending under the weight of larger coolers, thus indirectly contributing to thermal stability.

Compatibility and Installation

Compatibility is a key factor for both products. The ASF-RED AM5 CPU Holder is exclusively designed for AMD's AM5 CPU and motherboard slots, supporting the X670 and B650 chipsets. It comes with an L-shaped screwdriver and thermal grease, allowing for straightforward installation. On the other hand, the Assassin X 120 SE supports a broader range of sockets, including Intel's 115X, 1200, 1700, and AMD's AM4. This versatility makes it a more universal option for users with different CPU configurations. Installation is made easier with the provided mounting plates and fasteners.

Noise Levels

Noise levels are an essential consideration for many users. The Assassin X 120 SE operates at a maximum noise level of 25.6 dB(A), ensuring a quiet operation during use. This is particularly important for users who prioritise a noise-free environment. The ASF-RED AM5 CPU Holder, being a passive support, does not generate any noise, but it is not designed to contribute to cooling performance directly. Therefore, if silence is a priority alongside effective cooling, the Assassin X would be the preferable choice.

Price vs. Value

When evaluating price versus value, the ASF-RED AM5 CPU Holder at C$10.99 offers a very specific utility—preventing CPU bending during the use of heavy coolers. However, it lacks active cooling capabilities. In contrast, the Assassin X 120 SE, priced at C$25.59, provides comprehensive cooling solutions for a range of CPUs, justifying its higher price point with enhanced functionality. Users must consider whether they need a support system or a full cooling solution based on their gaming or computing needs.

Brand Reputation and Experience

Thermalright has over 20 years of experience in the computer accessory market, establishing a reputation for quality and innovation. Both products reflect this heritage, with the ASF-RED AM5 focusing on niche requirements while the Assassin X 120 SE aims to offer a reliable cooling solution for a broader audience. The brand's commitment to research and development is evident in the design and functionality of both products, which cater to different segments of the market.

Which should you buy?

In conclusion, the choice between the Thermalright ASF-RED AM5 CPU Holder and the Thermalright Assassin X 120 SE CPU Air Cooler hinges on your specific needs. If you require a simple solution to prevent CPU bending, the ASF-RED AM5 is a cost-effective choice at C$10.99. However, if you seek a comprehensive cooling solution that supports a variety of CPU sockets and offers efficient cooling performance, the Assassin X 120 SE at C$25.59 is the way to go. Ultimately, your decision should be based on whether you need support for your CPU or an active cooling solution.
