I'm not sure about a coolant temperature sensor that kicks the fan on earlier - but I know that if it's running too hot it most likely has nothing to do with the fan.
If you just want the fan to come on earlier because you're paranoid about the engine overheating - wire in a toggle switch or button and turn it on yourself when you think it should be on... I find that the fan on my car doesn't come on too often because I do more moving than stopping.
