Have a fan that is about the size of a register and 3 inches tall. You set it over the register. When it senses air coming thru the register it turns on sucking more air thru that register. Used it for a while in my hot bedroom for my bro with MS. It couldn't make up the 5 degree difference in that bedroom so put a window A/C unit in. There is a ceiling fan in that room as well.

Took the window A/C out after my bro with MS moved in with his girlfriend. That room also didn't get as hot. It was the only room in my how that got afternoon and evening sun. The sweet gum tree and crepe mertyles have grown up to shade that room much better.

If you would like to borrow and try out that register fan thing you are welome to.

The window A/C unit is in my next door neighbors garage. He borrowed it and just never has bothered to carry it back. Said to tell him if I needed it. Seems we are both fairly lazy. You can borrow it too if that will help.

Back when my bro lived here we had to keep the house at 70°F or he would start sweating and couldn't move. Mom and I got used to it being 70°.
