If that fan has no speed control, your house will sound like a 747 preparing for take off. I take it you have heard what a car fan sounds like running at full speed? And that's usually in an ambient environment (i.e outside). 8-10A is A LOT of current, don't even try to run this off your computer's PSU. Even if you power it off a normal outlet, if the current draw is too high you might blow a fuse -- not a good idea.

Overall this doesn't sound like a good idea to me, have you looked into alternatives at all that might be a bit more feasible?
