This is normal operation. It is either a temporary cooling phase (3–5 mins) or a result of the Network Standby feature being enabled.

Detailed Explanation:

1. Cooling Down Period

• Behavior: The fan remains on for 90 seconds to 5 minutes after pressing the power off button.

• Purpose: To dissipate residual heat from the lamp. Do not unplug the power cord until the fans stop completely to prevent hardware damage.

2. Network or Standby Settings

• Behavior: The fan stays on indefinitely at a low speed while in standby.

• Reason: The fan runs to cool communication components when [Network Control] or [CEC/Quick Start] features are active.

• How to Disable: If you prefer the fan to turn off completely after the cooling phase, navigate to:

• Menu > Option > Network > Off.

• Alternatively, set the [Standby Mode] to [Eco].

Important Notes:

• Tip: Setting the Standby Mode to "Eco" ensures the fan shuts down fully and reduces power consumption to under 0.5W.
