ASUS ROG RYUJIN III 240 ARGB liquid cooler

3.5-inch LCD monitoring block

The ROG Ryujin III 240 ARGB is an all-in-one liquid CPU cooler built around a 240 mm aluminium radiator and a copper cold plate measuring 89 x 91 x 101 mm. It supports AMD Socket AM4, AM5 and Intel LGA 1150, 1151, 1155, 1156, 1200 and 1700 platforms. A 3.5-inch LCD on the pump head shows real-time hardware data or custom GIF animations. The unit ships with 400 mm sleeved rubber tubes for flexible routing.

Asetek 8th gen pump and magnetic daisy-chain fans

The integrated Asetek 8th generation pump uses a three-phase motor to increase flow and reduce impedance while lowering acoustic output. Two 120 mm ARGB fans with a ring-shaped frame design spin between 600 and 2200 RPM, delivering 70.07 CFM at 36.45 dB(A). Their magnetic daisy-chain connectors simplify cable management and synchronise lighting effects through Armoury Crate software, which also controls pump speed, embedded fan curves and LCD content. A one-year AIDA64 licence is included for extended sensor logging.

240 mm radiator capacity and clearance limits

The 279.5 x 120 x 30 mm radiator fits standard dual-fan mounting locations and handles typical mainstream and enthusiast CPU thermal loads. The 400 mm tube length reaches most mid-tower and full-tower layouts but may fall short in oversized chassis or rear-exhaust routing. Builders needing greater surface area for sustained heavy overclocks or silent operation at extreme wattages will require a larger radiator format.
