The ASUS ROG Ryujin III 240 is an all-in-one liquid CPU cooler built with an 8th-generation Asetek pump to facilitate heat transfer from the processor. Its thermal assembly utilizes a 240 mm aluminum radiator paired with two 120 mm fans designed to dissipate heat under sustained workloads. A copper cold plate makes direct contact with the CPU integrated heat spreader for thermal exchange, and the pump housing includes an embedded fan to deliver airflow to the motherboard's voltage regulator module (VRM).
This cooler incorporates a 3.5-inch LCD screen on the pump housing, which can be configured to display real-time system metrics or custom graphics and animations. Control over the display, fan performance, and integrated ARGB lighting is managed through the Armoury Crate software suite via a USB header connection. For installation flexibility, the unit is fitted with 400 mm braided tubes and offers broad compatibility with current Intel and AMD sockets, including LGA 1700 and AM5.
