The ASUS ROG Ryujin III WB (part number 90RC00V0-M0UAY0) is a black CPU water block for custom open-loop liquid cooling, featuring a 3.5-inch full-color IPS LCD (60 FPS, 24-bit), an embedded Axial-tech VRM fan (5100 RPM, 21.08 CFM), an Asetek-powered copper cold plate with 178 micro cooling fins, and support for Intel LGA 1851/1700 and AMD AM5/AM4.
It brings the Ryujin III display and VRM-cooling fan to enthusiasts who build their own water-cooling loop, showing system stats or custom animations right on the CPU block. ASUS states the embedded fan can lower VRM temperatures by up to 35°C (tested on Core i9-13900K with ROG Maximus Z790 Hero). Radiator, tubing, coolant and other loop parts are sold separately.
