What this product is

The ASUS ROG Ryujin III WB WHT is a white CPU water block built for custom liquid-cooling loops. It pairs an Asetek-powered copper cold plate with 178 micro-cooling fins and a 3.5-inch full-colour LCD running at 60 FPS. An embedded axial-tech fan delivers 21.08 CFM to lower motherboard VRM temperatures by up to 35°C. The block measures 89 x 89 x 101mm and includes all-copper ROG fittings plus a cable organiser. Compatible with Intel LGA 1700, 1200, 1150, 1151, 1155, 1156 and AMD AM4, AM5 sockets.

Who it suits and who it does not

This block suits enthusiasts building a custom loop who want integrated VRM airflow and a high-refresh LCD for system stats or custom graphics. It fits the mainstream Intel and AMD desktop sockets listed in the specifications. Builders using HEDT or server platforms not listed above cannot mount this unit. Users planning an air-cooled or all-in-one build have no use for a bare water block. Anyone whose case or loop layout cannot accommodate the 101mm block height should verify clearance first.

The deciding specification

The block compatibility list is the single specification that decides whether this part fits your motherboard. It covers Intel LGA 1700, 1200, 1150, 1151, 1155, 1156 and AMD AM4, AM5. If your CPU socket is not in that list, the water block will not mount. No other specification overrides this constraint.

Questions about this item

What custom-loop components must I already have for the ROG Ryujin III WB WHT to function?

You need a pump, reservoir, radiator, tubing and coolant to complete the loop; the block includes copper fittings for G1/4 threads.

Will the embedded axial-tech fan clear tall VRM heatsinks on my existing motherboard?

The fan sits above the block and is designed to lower VRM temperatures by up to 35 °C on compatible Intel LGA 1700, 1200, 115X and AMD AM5, AM4 boards.

How can I verify the 3.5-inch LCD is running at its specified 60 FPS after installation?

Open the Armoury Crate display settings and confirm the panel shows a smooth 60 FPS animation or real-time hardware read-out without stutter.
