One thing I have done to my '5100s but not to my '5200 as of yet, is to
connect 12V through a low value resistor at the pad where the fan's
positive lead connects to keep the fan running slowly, but running all
the time.  It probably also helps that I don't get a chance to ragchew
as much as I used to so the finals last longer.   ;-)
