That coolant temp isn't insanely high for idling. Maybe a little more than expected. Does it go down right away when you start driving?
I would assume that the the 3.0si has an electric fan rather than a fan clutch since it's an N52. Might still be worth checking to see if the fan is running properly and pushing enough air. If you turn the A/C on the fan should ramp up so that's another test you can try.
