A Couple Of Ideas

From what you have posted I'm not convinced you are really overheating.
Get yourself one of those fancy infrared thermometers and find out what is really going on temp wise.
Run a temporary jumper wire from the sending unit to the gauge. Any grounding of the wire sending unit->gauge will give a false high reading. Are you sure the sending unit is matched to the gauge? You can check the gauge as follows: Disconnect the wire from the sending unit at the gauge. Power up the gauge. It should peg low. Next take a short wire and connect the sending unit terminal of the gauge to ground. When you power up the gauge it should peg high. Don't leave the gauge powered up for more than a minute or two when the engine isn't running because when you power up the gauge you are also powering up the coil.
