## Summary description

The ASUS ROG RYUJIN III 240 is an all-in-one liquid cooler designed for efficient CPU cooling. It features a 12 cm fan with an airflow of 121.8 m³/h, ensuring optimal thermal performance. The sleek black design complements any gaming setup, making it a perfect choice for gamers and PC builders looking for reliable cooling solutions.

## Long description

The ASUS ROG Ryujin III 240 is an all-in-one liquid cooler with a 3.5-inch full-color LCD built into the pump housing, a high-capacity 240 mm radiator and two 120 mm fans. The display shows system information such as clock speeds, voltages, temperatures, fan speeds and water flow, or can present custom images and animated GIFs. An embedded Axial-tech VRM fan improves airflow around the motherboard VRM, while an Asetek-designed pump and coldplate combination and long braided tubing circulate coolant for lower CPU temperatures. The cooler is finished in black and supports a wide range of Intel and AMD sockets, offering straightforward compatibility for many builds.
Advantages
The built-in 3.5” LCD provides live system monitoring and supports personalized animation or custom wallpapers. An upgraded embedded Axial-tech fan enhances VRM cooling and can reduce motherboard VRM temperatures. The cooler uses an 8th Gen Asetek pump and a large radiator combined with two quiet 120 mm fans (Noctua IndustrialPPC in the source description) to improve overall CPU thermal performance. Software control allows adjustment of pump and fan speeds, and a one‑year subscription to AIDA64 Extreme supplies additional live telemetry for the display.
Suitable for
Gaming PCs with mid-size to compact cases compatible with 240 mm radiators
PC builders who want integrated system monitoring on the cooler
Systems that require improved motherboard VRM airflow
Intel and AMD desktop platforms listed in the product specifications

Activate the included AIDA64 Extreme subscription to display additional telemetry on the screen if desired.
Usage recommendations
Use the manufacturer software to set pump and fan profiles according to workload for balanced noise and cooling. Ensure case airflow complements the embedded VRM fan to maximize VRM cooling benefits, and verify motherboard compatibility before installation.
