インストールガイド
Follow these steps carefully to install your Thermalright Assassin X 120R SE PLUS CPU Cooler. The installation process varies slightly depending on your CPU socket type (AMD or Intel).
1. AMD AM4/AM5のインストール
- マザーボードを準備します。 For AMD AM4/AM5, remove the existing plastic brackets around the CPU socket. Keep the motherboard backplate in place.
- スタンドオフの取り付け: Place the four red plastic standoffs onto the motherboard's CPU cooler mounting holes.
- 金属ブラケットを取り付けます。 Position the two metal brackets over the plastic standoffs and secure them with the provided AM4 screws. Tighten them evenly.

2. Intel LGA1700/115X/1200/1851 Installation
- バックプレートの準備: Adjust the mounting hole position on the universal backplate to match your Intel socket (e.g., 115X or 1700).
- バックプレートの取り付け: Place the adjusted backplate on the backside of your motherboard, aligning the holes with the CPU socket.
- スタンドオフの取り付け: From the front side of the motherboard, install the four blue Intel plastic standoffs into the backplate.
- 金属ブラケットを取り付けます。 Position the two metal brackets over the plastic standoffs and secure them with the provided Intel screws. Tighten them evenly.

3. 共通手順(全ソケット)
- サーマルコンパウンドを塗布する: Apply a small amount of thermal compound (pea-sized dot or line method) to the center of your CPU's IHS (Integrated Heat Spreader).
- Remove Heatsink Sticker: Ensure you remove the protective sticker from the heatsink's base before mounting.
- ヒートシンクの取り付け: Carefully place the heatsink onto the CPU, aligning the mounting nuts with the screws on the installed brackets. Tighten both nuts evenly with a screwdriver until snug. Do not overtighten.
- ファンの取り付け: Attach the fan clips to the 120mm PWM fans. Then, clip the fans onto the heatsink, ensuring proper airflow direction (typically pushing air through the heatsink towards the rear of the case).
- ファンケーブルを接続します。 Connect the 4-pin PWM power cables from the fans to the CPU_FAN header(s) on your motherboard.

操作手順
Once installed, the Thermalright Assassin X 120R SE PLUS CPU Cooler operates automatically. The PWM (Pulse Width Modulation) fans adjust their speed based on CPU temperature, providing efficient cooling while minimizing noise. Ensure your motherboard's BIOS/UEFI settings are configured to allow PWM control for the CPU fan header.
- 初期ブート: After installation, power on your computer. Monitor CPU temperatures using system monitoring software to confirm proper cooler function.
- BIOS/UEFI設定: Access your motherboard's BIOS/UEFI to verify that the CPU fan is detected and operating in PWM mode. You can often customize fan curves here to suit your preference for noise and cooling performance.
- 気流: Ensure that the fans are oriented correctly to draw cool air through the heatsink and exhaust warm air out of the case. The dual fan configuration (one intake, one exhaust reverse airflow fan) creates strong airflow.
メンテナンス
定期的なメンテナンスを行うことで、CPU クーラーの最適なパフォーマンスと寿命が確保されます。
- ほこりの除去: Periodically clean dust from the heatsink fins and fan blades using compressed air or a soft brush. Accumulation of dust can reduce cooling efficiency.
- ファンの検査: Check the fans for any signs of wear, damage, or unusual noise. Ensure fan clips are securely attached.
- サーマルペースト: While not frequently required, if you remove the heatsink for any reason, it is recommended to clean off the old thermal paste from both the CPU and heatsink base and apply a fresh layer before reinstallation.
トラブルシューティング
CPU クーラーに問題が発生した場合は、次の一般的なトラブルシューティング手順を参照してください。
- 高いCPU温度:
- Verify that the heatsink is securely mounted and making good contact with the CPU.
- サーマルペーストが正しく均一に塗布されているかどうかを確認します。
- Ensure fans are spinning and oriented for proper airflow.
- ヒートシンクとファンにたまったほこりを取り除きます。
- Check case airflow and fan configuration.
- ファンが回転しない:
- Ensure fan cables are securely connected to the CPU_FAN header(s) on the motherboard.
- BIOS/UEFI 設定をチェックして、ファン制御が有効になっており、非常に低い RPM に設定されていないことを確認します。
- Test fans by connecting them to a different fan header if available.
- 異常なファンの騒音:
- Inspect fan blades for any obstructions or damage.
- Ensure fan clips are properly seated and not vibrating against the heatsink.
- Check fan bearings for wear; consider replacing the fan if noise persists.
