+### 风扇在系统关机后仍然开启
+
+有用户报告 Penta SATA HAT 的风扇在系统关机后仍然保持开启状态。这可能是由于以下原因：
+
+1. **电源管理问题**：某些电源配置可能导致风扇在关机后继续供电
+2. **软件配置问题**：`rockpi-penta` 服务可能未正确停止
+3. **硬件设计**：风扇可能由独立的电源电路供电
+
+**解决方案**：
+
+1. **检查电源连接**：确保系统完全断电，而不是进入待机状态
+2. **停止服务**：在关机前手动停止 `rockpi-penta` 服务：
+   ```bash
+   sudo systemctl stop rockpi-penta.service
+   ```
+3. **修改配置**：如果不需要风扇功能，可以禁用风扇或降低温度阈值：
+   ```ini
+   [fan]
+   lv0 = 60  # 提高温度阈值，使风扇更少启动
+   lv1 = 65
+   lv2 = 70
+   lv3 = 75
+   ```
+4. **物理断开**：如果问题持续存在，可以考虑物理断开风扇连接
+
+**注意**：风扇在关机后短暂运行可能是正常现象，特别是在高温环境下。如果风扇持续运行，建议检查系统是否完全关机。
 ```

+## Troubleshooting
+
+### Fan remains on after system shutdown
+
+Some users have reported that the Penta SATA HAT fan remains on even after system shutdown. This could be due to:
+
+1. **Power management issues**: Certain power configurations may keep the fan powered after shutdown
+2. **Software configuration problems**: The `rockpi-penta` service may not be stopping properly
+3. **Hardware design**: The fan may be powered by an independent power circuit
+
+**Solutions**:
+
+1. **Check power connection**: Ensure the system is fully powered off, not just in standby mode
+2. **Stop service**: Manually stop the `rockpi‑penta` service before shutdown:
+   ```bash
+   sudo systemctl stop rockpi‑penta.service
+   ```
+3. **Adjust configuration**: If fan functionality isn’t needed, disable the fan or raise its temperature thresholds:
+   ```ini
+   [fan]
+   lv0 = 60  # Raise thresholds so the fan runs less often
+   lv1 = 65
+   lv2 = 70
+   lv3 = 75
+   ```
+4. **Disconnect physically**: If the problem persists, consider physically disconnecting the fan
+
+**Note**: A brief fan run after shutdown may be normal, especially in hot environments. If the fan continues to run, check whether the system is completely powered down.
