ASUS ROG Ryujin III 240 ARGB All-in-One CPU Liquid Cooler - Black
Go cooler than cool with the Ryujin III. An expansive 3.5-inch LCD screen displays live system stats, animated GIFs, or even your own custom artwork. Underneath, a new 8th Gen Asetek pump quietly, paired with larger coolant tubes, keeps the latest processors from Intel and AMD cool, while an embedded Axial-tech fan helps control motherboard VRM temps. And the coolant within flows through a higher capacity radiator graced with two ROG 120 mm ARGB fans that utilize magnets to make installation a snap.
Magnetic Daisy-Chainable Fans:
The customizable ARGB fans snap together with a magnetic connector that links the fans and transmits control signals and power. Only one cable is required for all two fans, making installation and cable management a breeze.
Full Color 3.5” LCD Display:
Internal memory has also been doubled to support clearer default animations and longer videos.
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.
Embedded VRM Fan:
A larger embedded Axial-tech fan improves airflow, reducing motherboard VRM temperatures by up to 35 Celsius.
Fan Control:
This generation of ROG all-in-one coolers now includes software that lets you control the speeds of your pump and embedded fan, in a way that should be instantly recognizable to FanXpert veterans.
