Price Comparison

When it comes to price, the Waveshare Active Cooler is significantly more affordable than the Thermalright Peerless Assassin 120 SE Black CPU Cooler. Priced at C$15.99, the Waveshare Active Cooler is an entry-level option, perfect for budget-conscious consumers. In contrast, the Thermalright Peerless Assassin is priced at C$46.79, making it nearly three times more expensive. This price difference highlights the market positioning of both products, with the Waveshare model catering to those looking for basic cooling solutions, while the Thermalright model targets users seeking advanced cooling performance.

Cooling Performance

The Thermalright Peerless Assassin offers superior cooling performance compared to the Waveshare Active Cooler. With a maximum air volume of 66.17 CFM and the ability to operate at a fan speed of 1550 RPM, the Thermalright cooler is designed for high-efficiency heat dissipation. In comparison, the Waveshare Active Cooler provides a modest air flow of 1.39 CFM at 8000 RPM. While the Waveshare cooler is suitable for basic applications, it cannot match the extensive cooling capabilities of the Thermalright model, making it clear that for intense CPU workloads, the latter is the better choice.

Build Quality

The build quality of the Thermalright Peerless Assassin is superior to that of the Waveshare Active Cooler. The Thermalright cooler features a refined construction that includes a blackened nano coating and a fully electroplated heat pipe, which enhances its durability and performance. Additionally, it has a fine micro-carved copper bottom that maximises heat dissipation. The Waveshare Active Cooler, while made of anodised aluminium, does not offer the same level of sophistication in terms of materials or design. Therefore, users looking for longevity and reliability in their CPU cooler may prefer the robust design of the Thermalright cooler.

Fan Technology

In terms of fan technology, the Thermalright Peerless Assassin benefits from dual PWM fans, which can significantly improve cooling efficiency. These fans operate at a quieter noise level of ≤25.6 dB(A) while providing a powerful airflow. The Waveshare Active Cooler, on the other hand, features a single fan that operates via pulse width modulation with tachometer control. While the Waveshare fan is efficient for its intended use, it lacks the dual-fan setup of the Thermalright, which allows for enhanced air circulation and better temperature management during heavy CPU loads.

Compatibility

Compatibility is another important factor when choosing a CPU cooler. The Thermalright Peerless Assassin supports a wide range of CPU socket types, including Intel’s LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, and LGA1851, as well as AMD’s AM4 and AM5 platforms. This extensive compatibility ensures that users can install the Thermalright cooler on various systems without hassle. In contrast, the Waveshare Active Cooler is specifically designed to be powered via the four-pin fan header on the Raspberry Pi 5, limiting its application to that particular platform. Therefore, the Thermalright cooler is the more versatile option for users with different CPU setups.

Installation Process

The installation process for both coolers varies significantly. The Thermalright Peerless Assassin comes equipped with metal fasteners for Intel and AMD platforms, making it easier to install on a variety of systems. The included mounting kit ensures that users can follow installation instructions or tutorials smoothly. In contrast, the Waveshare Active Cooler is a simpler device, designed primarily for the Raspberry Pi 5, which may make it easier for users familiar with that platform. However, the simplicity comes at the cost of versatility, as the Waveshare model does not accommodate other systems. Users seeking a cooler that can easily adapt to different builds may find the Thermalright's installation process more advantageous.

Aesthetic Appeal

Aesthetic appeal can be a deciding factor for many consumers when selecting a CPU cooler. The Thermalright Peerless Assassin features a sleek black painted design with a refined finish that adds a modern look to any build. Its dual tower and dual fan setup provide a visually striking appearance that can enhance the overall aesthetics of a gaming or high-performance PC. In contrast, the Waveshare Active Cooler has a more utilitarian design, focusing on functionality over style. While adequate for its purpose, it may not attract users looking for a visually appealing component. Therefore, for those who prioritise aesthetics in their builds, the Thermalright cooler is the more attractive option.

Which should you buy?

Choosing between the Waveshare Active Cooler and the Thermalright Peerless Assassin 120 SE Black CPU Cooler ultimately depends on your specific needs and budget. If you are looking for an affordable and straightforward cooling solution for a Raspberry Pi 5, the Waveshare Active Cooler at C$15.99 will serve you well. However, if you require superior cooling performance, build quality, and compatibility for a wide range of CPU platforms, the Thermalright Peerless Assassin at C$46.79 stands out as the better choice. For users seeking high efficiency and robust performance in demanding environments, the Thermalright cooler is the clear winner.
