Assuming it's done to spec mechanically, perhaps the fan's just pushing too
much air too fast? Not an exptert by any means, but I do know you can often
adjust the pulleys (set screw on the motor pulley can make it bigger &
smaller).
Or, there is air supposed to be entering somewhere else? It almost
sounds like all the air is being pulled in thru one opening? Usually there
are more than one, sometimes several; are any closed off?

Save your wild-assed guesses for something you actually have
information about.
