Ismalley,
For what it is worth, I live in the Palm Springs area. I had Jim Forgione make a special resistor that turns on the dual aux fans at 90C My car always runs in the 85-92C area. yes, the fans are on most of the time but like you I have a guy who rebuilds motors quite reasonably. In October, I simply pull the added resistor and return to normal operation.
