Shove a pencil (or anything that will fit) through the fan to keep it from 
spinning.  Turn on your computer.  If you don't hear the noise anymore, you
found the problem.  You probably *should* have a vent fan from keeping the
machine from heating up too much.  I wouldn't recommend leaving the pencil
in the fan as the fix.  Replace the fan motor - it should be cheap.
