When fan mode is set to Auto, the fans will run at variable speed, depending on the LED panel temperature. The fans will start running on very low speed when the temperature reaches 50°C, and turn off at 45°C. If the temperature increases, then the fan speed will increase also.
When running in Quiet, Medium or High speed modes, the fans will run continuously at the specified speed regardless of the LED panel temperature. If the panel temperature exceeds the safety limit of 75 °C then the fans will automatically switch to high speed mode, until the temperature falls below the limit.
In Pause mode, the fans will stop running. When the LED panel temperature reaches 70°C, the fans will turn onto Quite mode, until the temperature falls below 60°C, when the fans will switch off again. If the panel temperature exceeds the safety limit of 75 °C then the fans will automatically switch to high speed mode, until the temperature falls below the limit.
If the LED panel temperature exceeds 80°C (regardless of the fan mode), then the light output will start to slowly dim to prevent damage to the system. The light output will NOT dim in any of the fan modes unless this critical temperature is exceeded.
