That really is the main consideration. A 30" fan requires TEN square feet
of exhaust to function to maximum. When you get to figgering vent space,
that's quite a bit. And if the fan gets bigger, then the exhaust area
multiplies accordingly.

I doubt they really allow enough air flow

open a ****ing window.

You misunderstood. I'm talking about the exhaust area in the attic. You're
"open a window" idea only works if you happen to have a window in your
attic. I do have one house that has one, but it's not 10 sq. ft.

Are you talking about a whole house fan, or an attic fan?

A whole house fan pulls air in from the house.
an attic fan just blows hot air out of the attic.

He said "whole house fan." That's pretty clear. They exhaust through
the attic.

The entire thread is about 'whole house fans'. They used to be called attic
fans however.
