ASUS ROG RYUJIN III 240 ARGB White Edition Processor All-in-one liquid cooler 12 cm 1 pc(s)

The ROG Ryujin III White Edition is an all-in-one liquid CPU cooler featuring a 3.5-inch full-color LCD on the pump housing, an 8th Gen Asetek pump, reinforced 400 mm tubing, a thicker high-capacity radiator, and two ROG 120 mm ARGB magnetic daisy-chainable fans. The LCD displays real-time system statistics, animated GIFs or custom images, while the built-in Axial-tech fan helps reduce motherboard VRM temperatures. The cooler is compatible with a broad range of Intel and AMD platforms and includes software support for pump and fan control plus a one-year AIDA64 Extreme subscription for advanced monitoring.

Advantages

The integrated 3.5-inch LCD provides live monitoring of clocks, voltages, temperatures, fan speeds and water flow, and supports personalized animations and custom wallpapers. Magnetic daisy-chainable ARGB fans simplify installation and cable management by requiring a single connector for both fans. Design improvements include a 32% larger cold plate for better CPU contact, reinforced sleeved tubing with a larger inner diameter for improved coolant flow, a radiator 3 mm thicker than the previous generation for increased cooling capacity, and an embedded Axial-tech fan that reduces VRM temperature on the motherboard by up to 35 °C.

How to use

Install the ROG Ryujin III White Edition following the motherboard and CPU socket instructions: mount the radiator in the case (ensure compatibility with case mounting points for a 279.5 x 120 x 30 mm radiator), attach the pump block to the CPU using the supplied bracket and thermal interface material, and connect the magnetic ARGB fans using the included magnetic daisy-chain connector. Connect power and control cables for the pump, fans and RGB to the appropriate headers or the cooler’s controller, then use the supplied software to configure pump and fan curves and to upload custom images or animations to the 3.5-inch LCD. Optionally activate the one-year AIDA64 Extreme subscription to display additional system telemetry on the LCD.

Recommendations

Before installation, verify case clearance for a thicker radiator and 400 mm tubing routing. Use the manufacturer’s mounting bracket and follow torque guidelines for secure CPU contact. Keep the embedded fan and radiator dust-free to maintain optimal cooling performance, and update the cooler software to access the latest control and display features.
