Bob,

I believe I've got an easy solution for you.  I assume that you have
yet to turn the fan around on the power supply, correct?  If memory 
serves me right, ZDS designed all these 150 series power supplies to have
the fan blow in.  This causes the warm air from the power supply to be
blown over the boards.  Doesn't do much cooling.  Simply remove the four
sheet metal screws from the fan on the power supply, turn it around 
and reinstall it (you may have to actually take the power supply out
to do this, but that too is a simple task). I've done this many times.  
This should solve your problem.
