Overview of Thermalright Assassin X 120R SE V2 and Thermalright Aqua Elite 360 V3
The Thermalright Assassin X 120R SE V2 is a budget-friendly air cooler priced at C$23.59, while the Thermalright Aqua Elite 360 V3 is a more premium liquid cooler costing C$91.70. Each cooler serves the same purpose but employs different technologies and designs to achieve CPU cooling.
The Assassin X 120R SE V2 utilises a straightforward air-cooling method with a PWM fan, whereas the Aqua Elite 360 V3 leverages a liquid cooling system, promising enhanced cooling performance. This fundamental difference sets the stage for a deeper comparison of their features, performance, and suitability for various PC builds.
Cooling Performance
When it comes to cooling performance, the Thermalright Aqua Elite 360 V3 has a clear advantage over the Assassin X 120R SE V2. The Aqua Elite features a 360mm radiator and a fourth-generation pump head designed for high heat dissipation. This design allows it to maintain lower CPU temperatures even under heavy loads, making it an excellent choice for high-performance systems.
In contrast, the Assassin X 120R SE V2 employs a single 120mm PWM fan with a maximum airflow of 66.17 CFM. While it is efficient for moderate use, it may struggle to keep up with extreme workloads compared to the liquid cooler. The Aqua Elite, with its efficient cooling capabilities, is better suited for overclocked CPUs and gaming setups that require sustained performance.
Noise Levels
Noise is a critical factor when selecting a CPU cooler, and both products perform quite well in this regard. The Assassin X 120R SE V2 operates at a maximum noise level of 25.6 dB(A), making it relatively quiet during operation.
On the other hand, the Aqua Elite 360 V3 has a slightly lower maximum noise level of 23 dBA, thanks to its advanced pump and fan design. While both coolers are designed to operate quietly, the Aqua Elite offers a slightly quieter experience, which can be a significant advantage for users who prefer a silent PC environment.
Design and Aesthetics
The design of both coolers reflects their intended use. The Thermalright Assassin X 120R SE V2 has a more traditional air cooler design, suitable for medium-sized cases with a height of 148mm. It features a self-luminous fan and an industrial strength build, ensuring durability and effective cooling.
In contrast, the Aqua Elite 360 V3 boasts a modern aesthetic with ARGB lighting that synchronises with the motherboard. Its octagonal pump head and black aluminium fin heat sink create a visually appealing setup that enhances any gaming rig. The design elements of the Aqua Elite cater not only to performance but also to users who value visual flair in their build.
Installation Process
The installation process can significantly impact user experience. The Thermalright Assassin X 120R SE V2 is designed for easy installation, featuring compatibility with a range of Intel and AMD sockets. Users can follow provided installation instructions or video tutorials to set it up without hassle.
Similarly, the Aqua Elite 360 V3 also supports a wide array of Intel and AMD sockets and comes with all necessary accessories for installation. However, due to its liquid cooling design, it may require a bit more effort to install compared to the air cooler. Users should be prepared to manage tubing and ensure proper placement of the radiator, which can be more complex than simply mounting an air cooler.
Compatibility
Compatibility is crucial when selecting a cooler, especially for custom PC builds. The Thermalright Assassin X 120R SE V2 supports multiple CPU socket types, including Intel’s LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, and AMD’s AM4 and AM5. This wide compatibility ensures that it can fit into a variety of systems without issues.
The Aqua Elite 360 V3 also supports a broad range of sockets, including Intel’s LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA2011, LGA2066, LGA1700, and LGA1851, as well as AMD’s AM4 and AM5. While both coolers are highly compatible, users should ensure their cases can accommodate the size and configuration of the chosen cooler, particularly for the larger liquid cooler.
Price Comparison
Price is a significant differentiator between the two coolers. The Thermalright Assassin X 120R SE V2 is priced at C$23.59, making it an affordable option for budget-conscious builders or those with less demanding cooling needs.
In contrast, the Thermalright Aqua Elite 360 V3 carries a price tag of C$91.70. This higher cost reflects its advanced liquid cooling technology and superior performance capabilities. While the Aqua Elite may seem expensive, for users looking for maximum cooling efficiency and aesthetics, the investment could be justified.
Which should you buy?
Choosing between the Thermalright Assassin X 120R SE V2 and the Thermalright Aqua Elite 360 V3 ultimately depends on your specific needs and budget. If you are looking for a cost-effective solution for moderate gaming or general use, the Assassin X 120R SE V2 is an excellent choice, offering reliable cooling at an accessible price point.
However, if you require superior cooling performance for high-end gaming or overclocking, the Aqua Elite 360 V3 is worth the investment. It provides enhanced cooling capabilities, a more visually appealing design, and slightly quieter operation, making it ideal for power users who demand the best from their systems.
