Immersive System Monitoring & Customisation
The standout 3.5-inch LCD display transforms your cooling system into a live dashboard, showing real-time CPU frequencies, voltages, temperatures, fan speeds, and coolant flow. You can also personalise it with custom GIFs, animations from the ROG gallery, or even your own text and images. This makes the Ryujin III not just a cooler, but a centrepiece of your build.
Enhanced Cooling Performance
A new 8th Gen Asetek pump with a 32% larger cold plate maximises heat transfer from modern processors. The 30 mm thick radiator (3 mm thicker than previous generations) and enlarged 7 mm inner diameter tubing improve coolant flow and heat dissipation. An embedded Axial-tech fan actively cools motherboard VRMs, reducing their temperatures by up to 35°C for more stable overclocking.
Magnetic Daisy-Chainable ARGB Fans
The two included 120 mm ARGB fans connect magnetically, requiring only a single cable for both power and control. This simplifies installation and keeps your build tidy. With nine blades per fan and PWM support, they deliver quiet yet powerful airflow, adjustable via intuitive software.
