You sure about that?
Check out Dave's comments in this thread:
The #14 head on the 603, really bad? For sure?
Additionally, it would make far more sense to monitor refrigerant pressure. The concern is the high side pressure gets too high, so the fan engages to bring the condenser temperatures down, and the pressure falls with the drop in temperature.
