Genius roommate

I probably sound really stupid but can someone explain pls?

Fans take air from back. If ice is there that means cooler air.

This is the same concept wealthy people had before air conditioning.

raise the ice higher, use strips of dish rags, or clothes, soak, and place one end in the ice, the cold icy water will be drawn into the clothe, creating a more efficient evaporative cooler, done this when it's been too hot, works well, chux wipes work best.
