Modern cars run at 210 because that's what the fan controller is programmed for.
The fan "controller" for the original poster comes on with the ignition. There's no excuse for engine coolant temp to be much higher than the thermostat rating AT IDLE OR CRUISE. (It would be higher under load.)
If the engine has already maxed-out the thermostat and cooling system under light load, there's no reserve capacity for operation under heavy load.
It takes a big-deal electric fan system to keep up with a pretty common OEM fan, clutch, and shroud system. Good electric fans do exist, but they're either taken from OEM-engineered vehicles at the Treasure Yard, or someone paid
big money for an aftermarket system. Typical aftermarket fan setups are on the skimpy side; and the shrouds tend to either not fit well, and/or block airflow at higher speed.
