our house in the Nashville area has a huge (cubic feet) attic that is
hotter then hell. There are 8 of what I call 'passive' vents mounted
near the peak, and plenty of soffet vents. Even so, there is
absolutely NO air flow. During the hot summer days, the few metal
shelves I have in there are HOT to the touch. So the attic is
absolutely useless as storage space for anything but the heartiest
items.

My plan is to replace 2 of the vents w/ those mushroom-shaped powered
vents, one on each end of the roof line, and block off the remaining
passive vents from the underside w/ a thin piece of plywood.I figure
this would force air to come in through the soffet vents and move all
that hot air out.

does that sound reasonable, and do any of you experts see a problem w/
that?
I mean blocking off the remaining vents should suffice, right, or do I
have to remove them and re-roof?

and can you believe that the dumb assed builder actually mounted some
of the vents so they cut across a rafter??? Lucky for me there are a
couple where the hole is completely between two rafters, or I'd have a
heck of a time mounting new vents.

thanks,

You will increase your energy consumption with powered fans, but it
will work. Don't block the existing vents, you can't have too many
vents. It will take time, but consider planting some shade trees on
the south or south-west side of the house.

Existing vents near the exhaust fan will "short circuit" the air flow. He wants the
air to be drawn from the lowest, furthest vents, not from the closest vent at the
top. Of course, it would be easy to experiment to find the best result.
