does the fan come on in our 6.0L's

I read somewhere that the the thermostat starts to open at about 185-190*F, and is fully open at about 205*F.

Guy's with aftermarket water temperature gauges, what do you see for temperatures???
 
Don't know the operating temp of the fan. The stock thermostat is rated at 104c (219.2f). Haven't done a test on one to see when it actually starts opening though.
