Overview

When it comes to CPU cooling solutions, the Thermalright Aqua Elite 240 V3 Liquid CPU Cooler and the Thermalright Assassin X 120 SE CPU Air Cooler offer two distinct approaches. Priced at C$71.90, the Aqua Elite is a liquid cooling solution, while the Assassin X is available at a more budget-friendly C$25.59 as an air cooler. Each product has its unique features and advantages that cater to different user preferences and system requirements.

Cooling Performance

The Thermalright Aqua Elite 240 V3 is designed for superior cooling efficiency. It features a fourth generation pump head and a 240mm radiator, allowing for a high heat dissipation rate. This liquid cooler operates with a maximum fan speed of 1,500 RPM, providing an airflow of 66.17 CFM while maintaining a low noise level of 23 dBA. In contrast, the Thermalright Assassin X 120 SE, with its 120mm design, also achieves a maximum airflow of 66.17 CFM but with a slightly higher noise level of up to 25.6 dBA. This indicates that while both coolers provide similar airflow, the Aqua Elite is likely to offer better cooling performance due to its liquid cooling capabilities and larger radiator size.

Design and Aesthetics

In terms of design, the Thermalright Aqua Elite 240 V3 stands out with its octagonal pump head and ARGB lighting. This cooler not only provides effective cooling but also enhances the visual appeal of your build with its colourful lighting effects that sync with your motherboard. The Assassin X 120 SE, while practical, does not feature ARGB lighting. It has a more traditional look, focusing on functionality over aesthetics. Users looking for a visually striking cooler may prefer the Aqua Elite, whereas those prioritising simplicity might opt for the Assassin X.

Installation Process

Installation can be a critical factor for many users. The Thermalright Aqua Elite 240 V3 supports various AMD and Intel sockets, including AM4, AM5, and LGA 1700, and comes with all necessary accessories for straightforward installation. The Assassin X 120 SE also supports multiple Intel and AMD sockets and is similarly designed for easy setup. However, the Aqua Elite’s AIO (All-In-One) design may require more space and a slightly more complex installation process compared to the compact and user-friendly Assassin X. For users who prefer a simpler installation experience, the Assassin X may be the better choice.

Compatibility

Both coolers are compatible with a range of CPU sockets, making them versatile options for various builds. The Thermalright Aqua Elite 240 V3 supports AMD AM4/AM5 and Intel sockets up to LGA 2066, while the Assassin X 120 SE is compatible with Intel 115X/1200/1700 and AMD AM4 sockets. However, the Aqua Elite has the advantage of supporting a wider range of Intel socket types. Users with more diverse or modern builds may find the Aqua Elite to be more accommodating in terms of compatibility.

Noise Levels

Noise levels can significantly affect the user experience, especially for those building a quiet PC. The Thermalright Aqua Elite operates at a maximum noise level of 23 dBA, which is relatively quiet for a cooler of its size and performance. On the other hand, the Assassin X 120 SE has a maximum noise level of 25.6 dBA, making it slightly noisier than the Aqua Elite. For users who prioritize a tranquil computing environment, the Aqua Elite's quieter operation may be more appealing.

Longevity and Reliability

Both coolers are built with longevity in mind. The Aqua Elite's pump head boasts a lifespan of up to 40,000 hours at a rotation speed of 3,300 RPM ± 10%, which is impressive for a liquid cooling solution. The Assassin X also offers durability, featuring S-FDB bearings and a service life of approximately 20,000 hours. While both products are designed for extended use, the Aqua Elite's superior lifespan makes it a more reliable choice for long-term users.

Price Consideration

Price is always a significant factor in purchasing decisions. The Thermalright Aqua Elite 240 V3 is priced at C$71.90, which reflects its advanced liquid cooling technology and design features. In contrast, the Assassin X 120 SE is priced at a budget-friendly C$25.59, making it an attractive option for users looking to save money without compromising too much on performance. For those on a tighter budget or who do not require the advanced cooling capabilities of a liquid cooler, the Assassin X presents a compelling choice.

Which should you buy?

Ultimately, the choice between the Thermalright Aqua Elite 240 V3 Liquid CPU Cooler and the Thermalright Assassin X 120 SE CPU Air Cooler depends on your specific needs and preferences. If you are looking for superior cooling performance, aesthetics, and lower noise levels, the Aqua Elite is the clear winner. However, if budget constraints are a priority and you need a straightforward, reliable air cooler, the Assassin X is an excellent option. Each cooler has its strengths, making them suitable for different types of users and builds.
