ASUS ROG Ryujin III 240
ASUS ROG Ryujin III 240 Review & Specifications
The ASUS ROG Ryujin III 240 by Asus is a Liquid CPU cooler designed for compatibility with LGA 1150, LGA 1151, LGA 1155, LGA 1156, LGA 1200, LGA 1700, LGA 1851, AM5, AM4 sockets.
This liquid cooler uses a high-efficiency CPU block made of Copper for optimal heat transfer. It features a 240 radiator with dimensions of 279.5 x 120 x 30 mm, paired with 2 fan(s) of 120 mm each. The fan(s) operate at a maximum speed of 2000 RPM with a noise level of 30.0 dBA, achieving a total airflow of 72.0 CFM. Please ensure your PC case can accommodate the radiator size and mounting configuration. You can check compatibility with our PC Builder, which filters cases based on radiator size. This cooler does not include RGB lighting, focusing instead on performance, reliability, and low acoustic output. The cooler is backed by a 6-year warranty, providing long-term reliability and manufacturer support.
Performance
ASUS ROG Ryujin III 240 is a high-end performance liquid CPU cooler built for CPUs with a TDP exceeding 200 W, delivering an excellent relative cooling performance score of 87.50%. It is particularly well-suited for high-end gaming PCs, as it helps exhaust heat directly outside the case, improving internal airflow and thermal headroom for powerful GPUs. While it can be used in workstation builds, caution is advised due to inherently lower reliability compared to air coolers. Liquid coolers offer top-tier thermal performance, often unmatched by air coolers, but come with increased complexity, more moving parts (such as the pump), a risk of coolant leakage, and a higher likelihood of requiring maintenance over time.
Cost-Effectiveness
The ASUS ROG Ryujin III 240 achieves a moderate performance-to-price ratio of 21.2% when compared to the best-performing air cooler_selected. Note: While liquid coolers typically trail behind in value, this cooler still provides respectable efficiency and is suitable for those prioritizing quieter operation and improved aesthetics.
