Overview of the Products

In this comparison, we examine the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Waveshare Active Cooler. The Thermalright model is significantly more expensive at C$23.59, while the Waveshare cooler is priced at C$15.99. Both products serve distinct cooling needs, appealing to different segments of the market.

The Thermalright Assassin X 120R SE V2 is a CPU air cooler designed for optimal performance in gaming and high-performance computing setups. In contrast, the Waveshare Active Cooler is tailored for use with Raspberry Pi devices, providing basic cooling capabilities at a lower price point. This price difference suggests that the Thermalright cooler is intended for users seeking higher performance, while the Waveshare product targets budget-conscious consumers or those with simpler cooling requirements.

Design and Build Quality

The design and build quality of a cooler can significantly impact its performance and longevity. The Thermalright Assassin X 120R SE V2 boasts a robust construction with industrial strength materials, including PBT and PC, ensuring durability. Its height of 148mm makes it suitable for medium-sized cases without obstructing memory installation.

On the other hand, the Waveshare Active Cooler features an anodised aluminium body, which contributes to its lightweight and portable design. However, its cooling capacity of just 1.39 CFM indicates that it is more suited for less demanding applications. While the Thermalright cooler is built for extensive usage in high-performance scenarios, the Waveshare cooler is designed for ease of use with Raspberry Pi devices, making it less versatile overall.

Performance and Cooling Efficiency

When comparing performance, the Thermalright Assassin X 120R SE V2 stands out with its efficient cooling capabilities. It incorporates a PWM fan that can achieve an airflow of 66.17 CFM and operates at a maximum noise level of 25.6 dB(A). This means that users can expect substantial cooling without excessive noise, making it ideal for gaming and intensive tasks.

In contrast, the Waveshare Active Cooler operates at 8000 RPM and delivers a mere 1.39 CFM. While it may be effective for smaller devices like the Raspberry Pi, it lacks the robust airflow necessary for demanding CPU cooling. This stark difference in cooling efficiency illustrates that while both coolers serve their purposes, the Thermalright model is far superior for high-performance needs.

Noise Levels

Noise levels are crucial when selecting a cooling solution, especially for gamers and content creators who require a quiet environment. The Thermalright Assassin X 120R SE V2 operates at a noise level of 25.6 dB(A), which is relatively quiet for a CPU cooler, allowing for a peaceful computing experience even under load.

In contrast, the Waveshare Active Cooler does not specify its noise level, but given its higher RPM and lower airflow, it may not provide the same quiet operation as the Thermalright model. Users who prioritize a quiet system may find the Thermalright cooler more appealing, as it is designed to balance performance with low noise output.

Compatibility

Compatibility is a key consideration when choosing a cooling solution, and the Thermalright Assassin X 120R SE V2 excels in this area. It supports a wide range of CPU sockets, including Intel’s LGA1150/1151/1155/1156/1200/1700/17XX and AMD’s AM4/AM5. This extensive compatibility ensures that the cooler can be used with various systems, making it a flexible choice for different builds.

In contrast, the Waveshare Active Cooler is specifically designed for Raspberry Pi devices, which limits its compatibility to that ecosystem. While it may excel in that niche, users looking for a versatile cooler for different CPU setups will find the Thermalright model far more accommodating.

Installation and User Experience

The installation process can affect the overall user experience with a cooling solution. The Thermalright Assassin X 120R SE V2 provides detailed installation instructions and video guidance, facilitating an easier setup for users. Its thoughtful design includes features that prevent obstruction of memory installation, enhancing the overall experience.

The Waveshare Active Cooler, while easy to install due to its simplicity, may not provide the same level of user experience for those who are working with more complex builds. Its design caters primarily to Raspberry Pi users, meaning those seeking a broader application may find the Thermalright cooler more user-friendly.

Price and Value

The Thermalright Assassin X 120R SE V2 is priced at C$23.59, reflecting its advanced features and performance capabilities. This price might seem higher, but for users needing serious CPU cooling, the investment is justified by its performance and build quality.

In contrast, the Waveshare Active Cooler is priced at C$15.99, making it an attractive option for those on a budget. However, its limited performance may not provide the best value for users who require effective cooling for more demanding applications. When considering price versus performance, the Thermalright cooler offers greater long-term value for serious users.

Which should you buy?

Ultimately, the choice between the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Waveshare Active Cooler boils down to your specific cooling needs and budget. If you are looking for a high-performance cooler with excellent compatibility, efficiency, and low noise levels, the Thermalright model at C$23.59 is the clear winner. It is designed for serious computing applications and can handle the heat generated by demanding processors.

On the other hand, if you are seeking a budget-friendly option for a Raspberry Pi or less intensive tasks, the Waveshare Active Cooler at C$15.99 may suffice. However, it is essential to consider whether its limited performance meets your requirements. Overall, for serious gamers and high-performance users, the Thermalright Assassin X 120R SE V2 is the recommended choice, while the Waveshare Active Cooler serves well for simpler applications.
