I know I should be watching the temp gauge, but I don’t constantly watch it everywhere I go. Just questions I have.

An electric fan is more efficient, especially if driving slow or idling. Mechanical fans were never any good even brand new, and I blame the fan shape design as well as the large gap needed between the fan blade tips and the shroud. This gap is to allow the engine to flex under load and not have the blades hit the edge of the shroud.
Most of the installs I do are on computer controlled vehicles, so it's easy to switch the fan on and off because the vehicle's computer has one or two fan outputs that can easily be programmed. The link below is a simple type of controller you want if you don't have a computer controlled engine. I've never used this particular one, but it's one I quickly found doing a search. As I said before, it senses coolant temperature, not fin temperature.
