Larry -
Coming in a bit late on this discussion, but...
When I went to an electric fan, I experimented a bit with the position
of the temperature sensor in the radiator, to get the fan to switch on
and off when I felt it should. It now switches on midway between N and
H, and switches off just the cool side of N.
