	A lot of manufacturers design the air flow this way so the heat
generated by the fan motor itself doesn't get injected into the equipment,
adding to the cooling burden. Fans give off a surprising amount of heat !

	It shouldn't be a problem. When I opened up my machine the *ONE*
fan was just resting in place with some foam tape around it to cushion
and (presumably) quiet it. Just flip the fan around ...
