Pretty much rules out fan clutch as well as the auxiallary electric, I would think. After about 20 mph airflow cools the radiator and condenser. Probably would have noticed engine temp rising anyway at a stop or in stop-n-go traffic.
Try pinching the heater hoses off.

Well, it's Florida in the summer so the engine temp does rise a *little* in stop and go, but it never goes past halfway on the gauge. How do I pinch off the heater hoses? AC systems are something I'm very unfamiliar with.
