cooling

The hotter you run it the more power it will make, until the oil cooks. That would be too-hot...
The stat trys to set the minimum temp. It has nothing to do with the maximum. The maximum is set by the ability of the rest of the system to shed heat. If the only time you are over heating, or think you are overheating,is with the car stopped and the engine idling, that speaks to the inability of the system to shed heat.Since you are stopped, the job goes to the fans and rad. Since everybody who runs that rad and a mechanical fan, has no problem keeping cool......that would point to the fans.

In post 12, you said "clutch fan".
In post 11, I said "Ford thermostatic clutch". I should have said- Ford Truck thermostatic clutch
Was yours a thermostatic clutch fan? or a viscous clutch fan?
Yeah, Chrysler makes thermostatics too; for stock engines. The Ford truck T-clutch works.; and keeps on working.And keeps on keeping on.

I had an OE Chrysler Thermostatic clutch fan. It was from some late 1970s truck IIRC.

The Contour Electric fan moves more air than that does by a lot, even on low speed. The OP probably has some much weaker aftermarket fans (CFM and shrouds vary greatly) so I'm not disagreeing with you that the fans aren't working, and yes, I know the thermostat controls the minimum temp...and we both agree that taking it out does not control the maximum temp, so there really should be one there.

They make full size trucks now with Electric fans, if you have good ones, they work. Why would you want to go back to an engine driven fan to loose power to "fix" a problem that doesn't seem to exist in the first place? If the OP never hits 210 degrees under any circumstance, why worry? We don't know that yet.
