Installing a fan on my 1040ST was a sinch.  First, I took the sucker apart.
(Warranty???  What warranty???  Oh yeah, do this 91 days after you buy the
machine.)  There is a beautiful place to mount the fan between the power 
supply and the disk drive right on top of the RF shielding.  I just cut a
hole there about 2"x2" and mounted the fan with 4 screws.  Since it was
a 12V DC fan, I just connected one wire to the +12V spot on the power supply
and the other to the negative spot.  These are labeled on the power supply
so you should have no trouble finding them.  Then I put the thing back 
together.  It fits perfectly.  Just go to your local Radio Shack and buy
the fan.  I think they have 2 models that will fit in this small space.  I
can't remember the part number.  It is about 3"x3"x1.5".  It is really
quiet too if you put a small resistor inline or a potentiometer to slow the
fan down a bit.  Even at full speed, however, the bugger is relatively 
quiet compared to a pee cee fan.  Bonne chance!
