I'm not sure that'd help.  Is your fan cycling frequently?  If not, the
running temperature is being set by the engine thermostat, not the fan
switch.  Remember, the fan switch comes on only when the *radiator*
reaches a particular temperature, and that may not be the same as the
engine coolant temperature if the thermostat isn't fully open.  I have
to be stopped in traffic for quite a while before the fan on my van
comes on.  I wired an LED across the low speed fan circuit so I could
see when it comes on.  (I did one for the high speed circuit, too, but
now I realize that was silly.  I manually energized the high speed
circuit the other day, and there's no way I need a light to tell me if
that one comes on!)
