2. 安全情報
- クーラーの取り付けやメンテナンスを行う前に、必ずコンピューターの電源を切ってください。
- Handle components with care to avoid damage. Avoid touching the thermal paste or the cold plate surface directly.
- Ensure all cables are properly connected and routed to prevent interference with moving parts (e.g., fan blades).
- Do not attempt to open the sealed liquid cooling loop. Doing so will void the warranty and may cause leakage.
- 製品を湿気や極端な温度から遠ざけて保管してください。
- この製品には小さな部品が含まれており、お子様には適していません。

4. セットアップとインストール
Follow these steps for proper installation of your Zalman Alpha2 RGB AIO cooler. Ensure your motherboard and CPU are compatible with the provided mounting hardware.
4.1 ラジエーターとファンの準備
- Attach the two 120mm fans to the radiator using the longer fan screws. Ensure the fan airflow direction is appropriate for your case (typically blowing air through the radiator and out of the case).

4.2 ラジエーターの取り付け
- Identify a suitable mounting location in your PC case (e.g., top, front, or rear panel) that supports a 240mm radiator.
- Secure the radiator to the case using the shorter radiator mounting screws.
4.3 CPUソケットの準備
- Intelソケットの場合は、マザーボードの背面に適切なバックプレートを取り付けます。AMDソケットの場合は、標準のAMDバックプレートを使用してください。
- Attach the correct standoffs to the motherboard's CPU socket mounting holes.
- If thermal paste is not pre-applied to the cold plate, apply a small pea-sized amount to the center of your CPU's Integrated Heat Spreader (IHS).
4.4 Install the Pump/Cold Plate
- Align the pump block with the standoffs on the motherboard.
- Place the appropriate mounting bracket over the pump block and secure it with the thumb screws or nuts provided, tightening them in a diagonal pattern until snug. Do not overtighten.

4.5ケーブルを接続します
- Connect the pump's 3-pin or 4-pin power cable to the motherboard's CPU_FAN or AIO_PUMP header.
- Connect the fan power cables to available fan headers on your motherboard or to a fan controller.
- Connect the RGB cables from the fans and pump to the included RGB controller or directly to your motherboard's 5V ARGB header (if supported). Refer to your motherboard manual for specific header locations.
5. 操作手順
Once installed and powered on, the Zalman Alpha2 RGB cooler will automatically begin cooling your CPU. The integrated display on the pump block will show the current coolant temperature.
- 温度表示: The digital display on the pump block provides real-time coolant temperature readings. This helps monitor the efficiency of your cooling system.
- RGB照明コントロール: If connected to a motherboard's ARGB header, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync). If using a dedicated RGB controller, refer to its specific instructions for lighting adjustments.

6. メンテナンス
定期的なメンテナンスを行うことで、最適なパフォーマンスが確保され、AIO クーラーの寿命が延びます。
- ほこりの除去: ラジエーターフィンとファンブレードの埃は、圧縮空気または柔らかいブラシを使用して定期的に除去してください。清掃中はファンが回転していないことを確認してください。
- ケーブル管理 Check that all cables are securely connected and not interfering with fan rotation or other components.
- 漏れ検査: While AIO coolers are sealed, it's good practice to occasionally inspect the tubing and connections for any signs of leakage, especially after moving the system.
- サーマルペースト: The thermal paste applied to the CPU cold plate typically lasts for several years. If you notice a significant increase in CPU temperatures over time, consider reapplying fresh thermal paste.
7。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| Fans or Pump not spinning/no power | Loose power connection; incorrect header connection; faulty component. | Check all power cables (SATA, fan headers, pump header). Ensure pump is connected to CPU_FAN or AIO_PUMP header. Test components if possible. |
| CPU温度が高い | Improper cold plate contact; insufficient thermal paste; radiator/fans clogged with dust; pump failure. | Re-seat the pump block, ensuring even pressure. Reapply thermal paste. Clean radiator and fans. Check if pump is running (listen for faint hum, feel for vibration). |
| RGB照明が機能しない | Incorrect RGB header connection (e.g., 12V RGB instead of 5V ARGB); software issue; faulty RGB component. | Ensure RGB cables are connected to a 5V ARGB header on the motherboard. Check motherboard RGB software settings. Verify connections to any external RGB controller. |
| Unusual noises (gurgling, grinding) | Air bubbles in the loop (gurgling); fan bearing issue (grinding). | Gurgling usually subsides after some operation. Try gently tilting the PC case to help move air bubbles. If grinding, identify the source (fan or pump) and consider replacement if persistent. |
