One way to quiet the DC fan in the Amiga 2000 is to reduce the voltage 
supplied to the fan.  The fan in my 2000 is rated at 12 VDC (190mA).  When
operated at 9 VDC, it is noticeably quieter and appears to have no problem 
keeping my 2000 cool.  I used a 38 ohm (1 watt) resistor in series with
the power line to the fan to reduce the voltage.   I don't recommend anyone
try this unless they know how to tell if their computer is running too
hot.  Because the fan will be spinning slower, the volume of air moved by
the fan is reduced.   Your computer could overheat.  If not right away, maybe
during the summer.

(the !@#$% fan is still too loud)
