No interior fan is going to make a fridge cooler. It is going to cool to the thermostat setting, fan or no fan.
No, and yes. The thermostat sensor (on my Dometic, anyway) is mounted to the cooling fins, so that's the temperature it senses. That's about the coldest spot in the fridge, because that's where the "cool" comes from. It's warmer at the bottom if there's no fan to move the air.
With a fan circulating the air, the temperature is very consistent throughout, and most of the fridge is colder than it would be without a fan.
