Overview of Thermalright Assassin X 120 SE ARGB CPU Air Cooler
The Thermalright Assassin X 120 SE ARGB CPU Air Cooler is a high-performance solution designed for gamers and PC enthusiasts. Priced at C$24.29, it features a robust cooling system supported by advanced technology. The cooler's dimensions are 125mm x 71mm x 148mm, making it suitable for medium-sized cases. With a weight of 0.645kg, it is both lightweight and efficient. This cooler employs a PWM fan that operates at a maximum speed of 1550 RPM, delivering an airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A). The Assassin X is compatible with various Intel and AMD sockets, making it versatile for different setups.
Overview of Waveshare Active Cooler
The Waveshare Active Cooler is an economical cooling solution priced at C$15.99. It is designed primarily for use with the Raspberry Pi 5 and operates on a 5V DC supply. This fan features a tachometer and utilizes pulse width modulation for speed control. Operating at a high speed of 8000 RPM, it produces an airflow of 1.39 CFM. The cooler is constructed from anodised aluminium, ensuring durability while remaining lightweight. Given its specifications, the Waveshare Active Cooler is particularly suitable for compact devices requiring efficient cooling without excessive noise.
Performance Comparison
In terms of performance, the Thermalright Assassin X clearly outshines the Waveshare Active Cooler. The Assassin X can handle a thermal design power (TDP) of 125 to 225W, making it ideal for higher-end CPUs. Its airflow of 66.17 CFM is significantly higher than the Waveshare's 1.39 CFM, which means the Thermalright cooler can effectively dissipate more heat. While the Waveshare operates at a considerable speed of 8000 RPM, its overall cooling output does not compare to the Assassin X. Thus, for users with demanding cooling needs, the Thermalright is the superior choice.
Noise Levels
When evaluating noise levels, the Thermalright Assassin X also takes the lead with a maximum noise level of 25.6 dB(A). This low noise operation is appealing for users who value a quieter computing environment. In contrast, the Waveshare Active Cooler, while not explicitly stated, operates at a higher RPM of 8000, which could potentially result in increased noise, although no specific dB rating is provided. For those who prioritize a silent operation, the Thermalright's design is certainly advantageous.
Build Quality and Materials
The build quality of both coolers reflects their target applications. The Thermalright Assassin X is made with a combination of industrial-grade materials such as PBT and PC, which enhances its durability and thermal efficiency. It also features S-FDB bearings, ensuring a longer service life. On the other hand, the Waveshare Active Cooler is constructed from anodised aluminium, which is lightweight and robust, but may not offer the same level of thermal performance or longevity as the materials used in the Thermalright cooler. Users looking for a long-lasting investment may find the Thermalright to be the better option.
Compatibility
Compatibility is a crucial factor when choosing a CPU cooler. The Thermalright Assassin X supports a wide range of socket types, including Intel's 115X, 1200, 1700, and various AMD AM4 sockets. This broad compatibility makes it a versatile choice for many systems. In contrast, the Waveshare Active Cooler is specifically designed for use with the Raspberry Pi 5. Therefore, while it excels in its niche market, it cannot match the versatility of the Thermalright cooler, which can be used across multiple platforms.
Price and Value
The prices of both coolers reflect their intended use and performance capabilities. The Thermalright Assassin X is priced at C$24.29, while the Waveshare Active Cooler is more budget-friendly at C$15.99. However, the higher price of the Thermalright cooler can be justified by its superior performance, compatibility, and build quality. For users seeking a reliable and efficient cooling solution for demanding applications, the investment in the Thermalright is likely to yield better long-term value compared to the Waveshare, which is more suited for casual use or specific projects.
Which should you buy?
Ultimately, the choice between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Waveshare Active Cooler boils down to your cooling requirements and system compatibility. If you're looking for a robust, versatile cooling solution capable of handling higher thermal loads, the Thermalright Assassin X is the clear winner with its superior performance, quieter operation, and extensive compatibility. However, if your needs are limited to compact devices like the Raspberry Pi 5 and you seek a cost-effective option, the Waveshare Active Cooler is a reasonable choice. Your decision should reflect the performance demands of your specific setup and your budget constraints.
