Aux fan should be on and the visco clutch locked up at that temp. I'd replace the visco clutch and find out why the aux fan won't run before getting too excited.

My 300D runs 100+ in slow traffic with the AC on, never had a problem yet.

As stated above, cracked head will show cold coolant tank pressure, oil in the coolant tank, water in the oil, or "mystery" coolant loss.
