Two possiblilities come to mind. How likely, I don't know.
Some passages in the rad have become permanently blocked up over the years
and the engine is not not getting full use out of the rads capacity.
I only mention the second one because the symptoms that you have described
are so similar to those that I had on another vehicle ... small internal
hairline crack(s) in the heads in which some coolant is getting into the
engine.
If you've noticed a little more white smoke coming from the exhaust
at start up and for a little while after and/or the coolant level goes
down over a month's time, then this may be a real possibility.
