4. 操作とソフトウェア制御
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照明: Synchronize the cooler's RGB lighting effects with other Aura Sync-enabled components in your system for a unified aesthetic.
- ファンコントロール: Utilize the precise PWM pump and fan control features within LiveDash to optimize airflow and static pressure, balancing cooling performance with noise levels.

5. メンテナンス
Regular maintenance ensures optimal performance and extends the lifespan of your liquid CPU cooler.
- ほこりの除去: ラジエーターフィンとファンブレードは、空気の流れを妨げて冷却効率を低下させる可能性のある埃の蓄積を防ぐため、定期的に清掃してください。圧縮空気または柔らかいブラシを使用してください。
- ファンの検査: Check fans for any signs of wear, unusual noise, or obstructions. Ensure they are securely mounted.
- チューブと接続: Inspect the tubing for any kinks, leaks, or damage. Ensure all connections are secure.
- サーマルペースト: 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。 トラブルシューティング
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.
- 高いCPU温度:
- ポンプが作動していることを確認します(わずかな振動を感じたり、かすかな音が聞こえたりすることがあります)。
- ファンが回転しており、空気の流れが正しい方向になっていることを確認します。
- ポンプ ヘッドが CPU にしっかりと取り付けられており、良好な接触が保たれていることを確認します。
- ラジエーターフィンにほこりがたまっていないか確認し、必要に応じて清掃します。
- Ensure LiveDash fan control settings are not set too low.
- Unusual Noise from Cooler:
- ノイズがファンから発生しているのか、ポンプから発生しているのかを特定します。
- 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 webサイト。
- 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.
