The Radio Shack fan is a 3" DC brushless, about $14.  I bought one but
haven't gotten around to installing it yet.  The posting I read about
it warned that this one is a tight fit.  The Panasonic fan someone
mentioned has a lower db spec so that sounds like a better solution.

I think this technique would be more appropriate for an AC fan.
