a fan propped against a window pumping in outside air above 95 degrees

You're supposed to hang wet bedsheets in front of the fan.

Old towels work, too. It is basically a field-expedient 'swamp cooler', and can lower inside temps considerably. The lower the relative humidity, the better the evaporative cooling effect works. If you have hard water, though, expect the towels or sheets to be a write-off at some point from the accumulated minerals in them.

If you have water, a mist (we have some black, flat, soaker hose which sprays a fine mist along its length) on/next to the side of the house can drop temps by 5-10 degrees inside, but if your water has lots of minerals in it, it could leave a mineral stain on your siding.

The idea is to create a microclimate, inside the home or just around it which is more bearable than that outside your immediate area.
