Fortunately, I have not experienced anything to that extent but it sure does sound like not enough air flow is being pulled thru the radiator by the fan. With the increase in speed the ram effect is keeping it cool.

I know others have mentioned Packards not having a shroud lets the fan pull air from directly in front of fan, but not necessarily thru the radiator. Since they didn't have problems new, wonder if any of the radiator cores have been blocked off in front of the fan area either with sediment or by a shop fixing leaks with the resulting reduced capacity?

One thing to try if there is a next time is roll down the windows & turn the heater on full blast. While you suffer, the added air flow thru an additional radiator of sorts may help. I drove home about 100 miles that way when a thermostat stuck barely open on a car. The engine temp stayed higher than normal with the heater going but not where it had been.
