Thermalright Peerless Assassin 120 Digital ARGB Black CPU Cooler Air with 6X6mm Waveshare Active Cooler

Introduction to CPU Coolers

When it comes to CPU cooling solutions, selecting the right product is crucial for maintaining optimal performance. In this comparison, we will evaluate the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Cooler against the Waveshare Active Cooler. The former is priced at C$62.90, while the latter is a budget-friendly option at C$15.99. Each product targets different user needs, making it essential to understand their features.

Design and Build Quality

The Thermalright Peerless Assassin 120 features a dual tower design, which is not only aesthetically pleasing but also functional for heat dissipation. The cooler is equipped with two high-speed fans and 6 pure copper heat pipes that enhance heat transfer. In contrast, the Waveshare Active Cooler is constructed from anodised aluminium, which provides durability but lacks the advanced cooling capabilities of its counterpart. While the Thermalright is designed for mainstream ATX chassis with a height of 162mm, the Waveshare is more compact, making it suitable for small projects or lower power applications.

Cooling Performance

In terms of cooling performance, the Thermalright Peerless Assassin 120 excels with a fan speed of 1850 RPM and an impressive airflow of 88.89 CFM. This combination ensures effective heat dissipation, essential for high-performance CPUs. On the other hand, the Waveshare Active Cooler operates at a much higher fan speed of 8000 RPM but delivers only 1.39 CFM. While this higher RPM may imply better cooling, the significantly lower airflow suggests that the Thermalright is the superior choice for handling thermal loads, especially in gaming or intensive computing situations.

Noise Levels

Noise can be a critical factor when selecting a CPU cooler. The Thermalright Peerless Assassin 120 operates at a noise level of ≤25.6 dB(A), which is relatively quiet for a high-performance cooler. In contrast, the Waveshare Active Cooler, despite its high RPM, does not provide explicit noise level specifications. However, it's reasonable to infer that the higher RPM may lead to increased noise, potentially making the Thermalright a more appealing choice for users who prioritise a quieter computing environment.

Compatibility and Installation

The Thermalright Peerless Assassin 120 is designed to fit mainstream ATX chassis, ensuring compatibility with a wide range of builds. Its dual fans and towers allow for efficient installation without obstructing high-capacity memory or graphics cards. The Waveshare Active Cooler, while smaller and more versatile, is primarily designed for use with devices like the Raspberry Pi, as it connects via a four-pin fan header. Therefore, while the Waveshare offers ease of installation in compact setups, the Thermalright is better suited for larger systems requiring robust cooling solutions.

Features and Technology

The Thermalright Peerless Assassin 120 boasts advanced features such as PWM intelligent temperature control, allowing the fans to adjust automatically based on CPU temperature. Additionally, it includes TRCC software for monitoring and controlling the cooler's performance, including the colour of the digital display. In contrast, the Waveshare Active Cooler features pulse width modulation control but lacks the extensive monitoring and customization options found in the Thermalright. This makes the Thermalright a more feature-rich choice for users who want to manage their cooling performance actively.

Price-to-Performance Ratio

Price is often a significant consideration when choosing between two products. The Thermalright Peerless Assassin 120 is priced at C$62.90, reflecting its advanced cooling technology and features. In comparison, the Waveshare Active Cooler is much more affordable at C$15.99, making it an appealing option for budget-conscious consumers or those with less demanding cooling needs. However, the higher price of the Thermalright is justified by its superior performance and additional features, particularly for users who require effective cooling for high-performance CPUs.

User Experience and Feedback

While specific user feedback is not available in the provided data, the features of each cooler suggest different target audiences. The Thermalright Peerless Assassin 120 is likely to appeal to gamers, content creators, and enthusiasts who demand high performance and low noise levels. Meanwhile, the Waveshare Active Cooler may attract hobbyists or those working on DIY projects requiring basic cooling solutions without the need for extensive features or high airflow.

Which should you buy?

Ultimately, the choice between the Thermalright Peerless Assassin 120 and the Waveshare Active Cooler depends on your specific needs and budget. If you require robust cooling for a high-performance system and value advanced features like PWM control and monitoring, the Thermalright at C$62.90 is the clear winner. Conversely, if you're looking for a simple, budget-friendly solution for a compact project, the Waveshare at C$15.99 could suffice. Your ideal choice will hinge on the performance requirements of your CPU and your willingness to invest in a cooling solution that meets those demands.
