Overview of the Products

In this comparison, we will examine the Thermalright Peerless Assassin 120 SE CPU Cooler and the Thermalright ASF-RED AM5 CPU Holder. The Peerless Assassin is a high-performance CPU cooler priced at C$48.90, while the ASF-RED is a dedicated CPU holder retailing for C$10.99. Both products come from Thermalright, a brand with over 20 years of experience in computer cooling solutions. Understanding the key features and specifications of each product will help consumers make an informed decision based on their specific cooling needs.

Design and Build Quality

The Thermalright Peerless Assassin 120 SE features an impressive design with dimensions of 125(L)x135(W)x155(H)mm and is constructed from aluminium and copper. Its dual tower heatsink configuration is designed for optimal heat dissipation, making it suitable for high-performance setups. In contrast, the ASF-RED AM5 CPU Holder is smaller, measuring 70(L) × 54(W) × 6(H) mm, and is crafted from all-aluminium alloy with an anodised sandblasting process. This ensures a premium finish and durability. While the cooler is built to handle high thermal loads, the holder is specifically designed to support the weight of the cooler to prevent CPU bending.

Cooling Performance

Cooling performance is a critical aspect when choosing a CPU cooler. The Thermalright Peerless Assassin 120 SE is equipped with two high-performance ARGB fans that operate at a maximum speed of 1550 RPM and produce a rated airflow of 66.17 CFM. With a noise level capped at 25.6 dB(A), it promises efficient cooling while maintaining a quiet operation. On the other hand, the ASF-RED AM5 CPU Holder does not provide cooling itself but enhances the cooling efficiency by preventing the CPU from bending under the weight of larger coolers. Therefore, the Peerless Assassin is the clear winner in terms of cooling performance, while the ASF-RED serves as a supportive accessory.

Compatibility

Compatibility is a vital consideration for computer builders. The Thermalright Peerless Assassin 120 SE is compatible with a range of Intel and AMD sockets, including Intel’s LGA 1150 through LGA 1851 and AMD’s AM4 and AM5. It is essential to note that the installation on AM4 and AM5 requires the original motherboard’s built-in backplate, which is not included. In contrast, the ASF-RED AM5 CPU Holder is specifically designed for AMD’s AM5 CPU, making it a perfect match for those building on this platform. If you are using an AM5 motherboard, the holder is a straightforward addition that enhances CPU stability.

Installation Process

When it comes to installation, the Thermalright Peerless Assassin 120 SE employs an SS2 install system that simplifies the mounting process. However, users need to ensure that their case and motherboard are compatible with its dimensions. The ASF-RED AM5 CPU Holder is designed for easy installation, equipped with an L-shaped screwdriver and featuring precise positioning for the AM5 socket. The inclusion of TF7 2g silicone grease enhances thermal conductivity and simplifies the cooling setup. For ease of installation, the ASF-RED clearly offers a more user-friendly approach, particularly for beginners.

Price Comparison

Pricing plays a significant role in the decision-making process. The Thermalright Peerless Assassin 120 SE is priced at C$48.90, reflecting its high-performance capabilities and robust design. Conversely, the ASF-RED AM5 CPU Holder is priced at a mere C$10.99, making it an affordable addition to any AM5 build. While the cooler represents a more considerable investment, its performance justifies the cost. The holder, however, is an economical solution for those looking to stabilise their CPU without breaking the bank.

Target Audience

The intended audience for each product differs significantly. The Thermalright Peerless Assassin 120 SE CPU Cooler is aimed at gamers and PC enthusiasts who require superior cooling performance for demanding applications. Its advanced design and cooling capabilities cater to high-performance CPUs. In contrast, the ASF-RED AM5 CPU Holder is targeted towards users with AM5 motherboards who want to prevent CPU bending caused by heavy coolers. This makes it an essential accessory for those prioritising the longevity and stability of their CPU.

Which should you buy?

Ultimately, the choice between the Thermalright Peerless Assassin 120 SE CPU Cooler and the Thermalright ASF-RED AM5 CPU Holder depends on your specific needs. If you’re looking for efficient cooling performance and are building a high-performance system, the Peerless Assassin is the clear choice with its advanced cooling technology and dual fan setup. However, if you already have a suitable cooler and are seeking a cost-effective way to support your AM5 CPU, the ASF-RED offers an excellent solution to prevent bending. In conclusion, consider your cooling requirements and budget before making a decision.
