The small fan on your desk is a purely aesthetic item, but it serves as a subtle indicator of your power status. When your power runs out, the fan will stop spinning, and the lights will flicker before going out completely. It's a visual cue that your time is running out.
Significance:
- Visual Cue: Its cessation indicates imminent power failure.
- Atmosphere: Its constant hum contributes to the game's oppressive atmosphere.
While you can't interact with it, the fan is a small detail that adds to the immersion and provides a subtle, non-UI warning about your dwindling power supply.
