:-) For the record, I have lots of fans, including the new one they
bought me at work. None are small enough to fit on the window sill.
(a cheap modern one that has no overhang.) I could put a fan on the
table next to me, but that wouldn't blow the cool outside air in after
sundown and all night.

Then buy a fan that fits INTO the window opening.

This is the perfect sized fan. I think after it was oiled again, it
only overheated because the blade wasn't spinning fast enough to blow
air through the vents. I"m so glad it works again. Plus I did like
fixing it.

One day that fan WILL catch fire. An electric motor that is powered and not
spinning is pretty much a short circuit.
