The problem I'm having is that the fans come on with the AC compressor even while driving down the highway when they aren't needed. What I would like to do is install some type of device that automatically disables the fans on the highway and allows them to operate as normal at idle and at lower speeds.
What if you're in a situation where you have high load on the engine above 50mph and the temperature gets too high? Perhaps some kind of mechanical issue.

I think you're wasting your time to be completely honest. You're trying to eliminate the waste of an inefficient alternator by changing the operating schema of your cooling fans....
