Here is one of my five attics:

Would an attic fan, of some sort, be feasible in this location?

The house has AC, and three floors, and it's insulated with the
loose stuff, at least anywhere where I can 'see' the rafters.

It's California. Northern. So, it's a pretty mild climate, but,
it's as hot as blazes in these attics, so, I was just wondering
if it's better to run the home heating system fans, or, put an
attic fan in to cool the house down, without running the A/C?
