Overview
COOLER THAN COOL
Go cooler than cool with the ROG Ryujin III. Its roomy 3.5-inch LCD screen displays live system stats or your custom artwork and animated GIFs. Underneath, an embedded fan upgraded with Axial-tech improves motherboard VRM thermals by up to 35° Celsius, and an 8th Gen Asetek pump and coldplate combine to deliver even lower CPU temperatures. Liquid is piped in through generously long braided tubing and chilled by a higher capacity radiator and two famously quiet 120 mm Noctua fans.
Full Color 3.5” LCD Display
System Monitoring The industry-leading 3.5-inch LCD built into the pump block delivers instant monitoring of clock frequencies, voltages, temperatures, fan speeds and water flow, or your custom GIFs.
Exploded View
The 8th Gen Asetek pump sports a 3-phase motor for higher flow and quieter operation, riding on a larger cold plate ideally sized for the latest Intel® and AMD processors.
New Cold Plate
The contact surface is now 32% larger to keep the chill on power hungry processors.

Enhanced Tubing
The sleeved rubber is wrapped in braided mesh, and the inner diameter has been enlarged from 5 mm to 7 mm to reduce flow resistance.
Thicker Radiator
279.5 x 120 x 30 mm radiator — 3 mm thicker than previous gen, for improved cooling performance.
Embedded VRM Fan
A larger embedded Axial-tech fan improves airflow, reducing motherboard VRM temperatures by up to 35° Celsius.
Noctua Industrial iPPC Fan
To overcome the thermal challenges of the latest multi-core CPUs, ROG Ryujin III offers industrial-grade Noctua iPPC-2000 PWM radiator fans that deliver high performance and minimal-noise operation.
