Very interesting usage and heating results.  You've obviously done your
homework.  I think for most of us, the controller will fill the bill.  In your
situation (and contest stations, etc.) some extra cooling does help to level out
the speed.  I'm tempted to dig out my old microMatic and run some automated
tests of my own using your parameters to see how mine does.  I would have
problem with the permanent setting of the minimum fan speed though, because, as
a recent retiree from the broadcast industry, I'm a firm believer that fans
whose bearings dry up and get tight are one of the biggest causes of failure in
electronic equipment that runs all the time - that and not cleaning filters. :o)
Since I leave most of my equipment on all the time, I would count on more fan
maintenance/replacement.

Interesting situation!  Thanks for the explanation.
