What temp should car run at? How to test aux fan? (archive)

My temp gauge is always a little over the half way point when I'm driving around. And will flutter between there and 5/8 when sitting. Is this normal?

I still have not been able to see if my aux fan/thermoswitch works after replacing the wires. From what I've heard the fan will not come on till temp reaches 3/4. How can I test it. I heard that if I jump the black wire with one of the others that are connected to the thermo switch the fan should run. Is this correct? I know this won't test the thermoswitch itself but it will atleast tell me if the wires are fine. Also I was thinking of just setting up a switch like i've seen on other cars to activate the aux fan. Has anyone else done this?
