Bert,
Since you have been running your unit for a long time, what temperature are
you holding your 5680 to? I suppose more to the point, I attached my unit
to a 1/2" think aluminum plate slightly larger than the 5680 footprint, and
that in turn is attached to a painted surface of a cabinet (no effort to
achieve max temp transfer there). The top (hidden mounting screw) of my
unit stabilizes at 140 F. It locks up just fine, but sometimes, after
several hours, it will unlock and fail to re-lock. I was wondering if I
need to drop the temperature.
