Any electronics stores in your area? Last time I bought computer fans, it was
at Frys; but only because Torrance Electronics was
closed at the time. Even Best Buy and Radio Shack have some shot at having
what you need.

Of course you'll first have to find out what you need, in terms of both
physical size and cfm. Most likely a computer fan will be
12v DC, but it wouldn't hurt to check that as well.
Usually (though certainly not always), ball bearing fans make more noise for
the same air movement. But they also last longer, and
give you warning when they are about to fail (by getting even louder). Sleeve
fans are quieter to begin with, but fail and stop
without making any extra noise.
