Let's see.....1 squealing fan....or.....
having a house in 90s° F with 100% humidity. I have no A/C. I'd love
to hear a fan squeal.

I have to laugh at the weather channel making a big deal out of 110
temps in the south west. That is DRY heat and is nothing compared to
having high humidity. Been out west when it's hot and dry and it's
not so bad. The only thing is my skin feels like there are bugs on it
because my skin is drying out.
