Mine tends to run anywhere from 190°-210°, but I have a pretty weak Mishimoto fan trying to cool a massive PWR radiator, so YMMV. I don't worry until it starts approaching 230°+...

Mine runs between 180 and 205. The fans switch off at 180 and it doesnt have much trouble staying there. 195 is a solid average during normal driving or a few pulls under boost. Very hot weather (100+) and long sprinted hill climbs will get me up around 230 in which case I pull it back to let it cool down
