## Summary description

The ASUS ROG Ryujin III 240 ARGB is an all-in-one liquid cooler designed for high-performance cooling. It features a 12 cm fan for efficient airflow and is compatible with various CPU sockets. The sleek black design and RGB lighting enhance the aesthetics of your build, while providing superior thermal management for gaming and intensive tasks.

## Long description

The ASUS ROG Ryujin III 240 ARGB is an all-in-one liquid cooler with a 240 mm radiator and two 120 mm ROG ARGB fans. It integrates a 3.5-inch full-color LCD on the pump housing for live system monitoring, animated GIFs or custom artwork. The cooler uses an 8th Gen Asetek pump with a larger cold plate, widened 7 mm coolant tubing and an embedded Axial-tech fan to assist motherboard VRM cooling. The unit is finished in black and includes 400 mm of tubing for flexible installation across a wide range of Intel and AMD sockets.
Advantages
The Ryujin III combines an expanded 3.5-inch display and increased internal memory for clearer animations and longer videos with a quieter, higher-flow pump design. Improved thermal contact from a 32% larger cold plate, thicker 30 mm radiator and upgraded 120 mm ARGB magnetic daisy-chainable fans simplify installation while improving heat dissipation. An embedded Axial-tech fan helps reduce VRM temperatures, and bundled software support allows pump and fan control plus live telemetry display via the LCD.
Suitable for
High-performance gaming PCs requiring effective CPU cooling
Workstations running CPU-intensive tasks such as rendering or simulation
Systems where integrated ARGB lighting and a customizable LCD are desired
Builds using Intel LGA or AMD AM4/AM5 sockets listed in compatibility

Usage recommendations
