3. Setup and Installation

Follow these general steps for installing your ASUS ROG RYUO 240 Liquid CPU Cooler. Refer to your motherboard manual for specific details regarding CPU socket preparation.

1. Prepare the CPU Socket: Install the appropriate backplate and standoffs for your CPU socket (Intel or AMD) as indicated in the accessory pack.
2. Mount the Radiator: Secure the 240mm radiator to an available fan mount in your PC case. Ensure proper airflow direction (intake or exhaust) based on your case's cooling design.
3. Install the Fans: Attach the two 120mm ROG Ryuo Fan Model 12 fans to the radiator using the provided screws.
4. Position the Pump Head: Carefully place the pump head onto the CPU, aligning it with the standoffs. The thermal compound is pre-applied.
5. Secure the Pump Head: Use the appropriate mounting brackets and thumb screws to secure the pump head firmly to the CPU socket. Do not overtighten.
6. Connect Fan Cables: Connect the 4-pin PWM fan cables from the fans to the fan headers on the pump unit or directly to your motherboard's CPU_FAN/CHA_FAN headers.
7. Connect Pump Power: Connect the pump power cable to an available AIO_PUMP or CPU_OPT header on your motherboard.
8. Connect USB Cable: Connect the included USB cable from the pump unit to an available internal USB 2.0 header on your motherboard. This is essential for software control of the OLED panel and RGB lighting.
9. Cable Management: Route all cables neatly to ensure proper airflow and a clean build.

4. Operation and Software Control

The ASUS ROG RYUO 240 features a 1.77" full-color OLED panel and Aura Sync addressable RGB lighting, both controllable via ASUS LiveDash software.

4.1. LiveDash Software

To fully utilize the OLED panel and RGB lighting customization, download and install the latest LiveDash software from the official ASUS support website. Ensure you also have the Aura Sync software installed for full compatibility.

• OLED Panel Customization: The LiveDash software allows you to display real-time system statistics (e.g., CPU temperature, fan speed), personalized logos, or custom animations on the 1.77" OLED panel. Supported image formats include GIF and JPG with a resolution of 160 x 128 pixels and a maximum size of 1 MB.
• Aura Sync RGB Lighting: Synchronize the cooler's RGB lighting effects with other Aura Sync-enabled components in your system for a unified aesthetic.
• Fan Control: Utilize the precise PWM pump and fan control features within LiveDash to optimize airflow and static pressure, balancing cooling performance with noise levels.

5. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your liquid CPU cooler.

• Dust Removal: Periodically clean the radiator fins and fan blades to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
• Fan Inspection: Check fans for any signs of wear, unusual noise, or obstructions. Ensure they are securely mounted.
• Tubing and Connections: Inspect the tubing for any kinks, leaks, or damage. Ensure all connections are secure.
• Thermal Paste: While thermal paste is pre-applied, consider reapplying it if you remove the pump head for any reason, or if you notice a significant increase in CPU temperatures over time.

6. Troubleshooting

If you encounter issues with your ASUS ROG RYUO 240, refer to the following common troubleshooting steps:

• No Power/No RGB/OLED Display Off:
  • Ensure all power cables (pump, fans) are securely connected to the motherboard headers.
  • Verify the internal USB 2.0 cable is correctly connected to both the pump unit and the motherboard.
  • Check LiveDash and Aura Sync software settings to ensure RGB and OLED are enabled and configured correctly.
• High CPU Temperatures:
  • Confirm the pump is running (you might feel a slight vibration or hear a faint hum).
  • Ensure fans are spinning and correctly oriented for airflow.
  • Verify the pump head is securely mounted to the CPU and making good contact.
  • Check for dust buildup on the radiator fins and clean if necessary.
  • Ensure LiveDash fan control settings are not set too low.
• Unusual Noise from Cooler:
  • Identify if the noise is coming from the fans or the pump.
  • If from fans, check for obstructions or loose mounting. Consider adjusting fan curves in LiveDash.
  • If from the pump, ensure the pump is running at an appropriate speed. Some pump noise is normal, but excessive gurgling might indicate air in the loop (which usually resolves itself over time).
• LiveDash Software Issues (e.g., OLED logo not changing):
  • Ensure you have downloaded and installed the latest version of LiveDash and Aura Sync software from the official ASUS support website.
  • Restart the LiveDash application or your computer.
  • Verify that custom images/animations meet the specified resolution (160x128 pixels) and size (1MB) requirements.
  • Some games or anti-cheat software may conflict with LiveDash. Try exiting LiveDash before launching such applications if you experience issues.
