We can eliminate the fan clutch because if the cluthc was the issue, as soon as it engages and "roars", temps would drop fast, but on my 300TE it does not. It just stops it rising further, but never cools it down enough.

Yup, I put the clutch from the 93 on my car, too. The fan cannot be stopped with a rag at idle when the engine is hot. The electric fans are operating correctly, too. It's something to do with the coolant not circulating and the thermostat is the only obvious obstruction in the system for the pump to overcome. If the thermostat isn't opening far enough, it would act exactly the way we are seeing.
