If you're running it with a fan and no water, it's a ... fan.
Swamp cooling relies on the fact that water evaporation cools nearby air.
You pull outside air into the wet medium, and pump the cooler
and more humid air through the house. It then exits the house through open
windows (to the poster who recommended closing all the windows,
that's going to completely undermine the whole thing).
