84 gl ea81 Electric fans dont kick on until 3/4 up the gauge, i would think they kick on just above half to bring them down to half. Mine always seemed to run halfway up the gauge. But is this right are they sopposed to come on that hot?

The stock gauge is merely a rough guess at the actual temp. They are notorious for reading high. Get a laser temp gun and check the inlet/outlet temps of the radiator.

 

Chances are that if the fans go on/off at regular intervals then there is nothing wrong other than a poorly reading guage or bad sending unit.
