Pete, the reservoir sits next to the radiator and the lines run down near when the AC compressor sits (from memory). Not too sure what my engine temp sits at, I think around 89 or so. Usually fans only need to be operated when your idling and when your at speed they actually decrease the airflow through your radiator. By the sound of it your radiator is a little bit too small. Maybe a temp operated thermo is the way to go.
