When the gauge is in the middle, the coolant temp in the thermostat housing is approx 88-90 degrees. So when the gauge is at 3/4, the temp is approx 94 degree, this is equal to your engine temp, but much higher as the temp in the bottom of the radiator.
Hope this explanation helps
I just now took a photo of the thermos switch for the fan, isn't it this? :

So, on the top not near bottom of the radiator
