Does that make the solution more complicated? There are about 20 little
capacitors, packed like mushrooms. Are you sure it can't be anything
else? BTW, if I later unplug it, the fan spins back up again. Maybe I
could just disable whatever shuts the thing down? (I'm somewhat
squeamish about spending two hours checking each and every capacitor
with a hot soldering iron - that'll _really_ dry out my capacitors :)
