Short answer:
1. Both top and bottom
2. 60C (140F) and bottom absorber coil
Long answer:
I originally bought the Valterra fridge vent fan kit that came with a rocker switch and a thermostat. The fan itself was junk and failed after less than a year but I kept the switch and thermostat to use with replacement fans. The best information I can find is the thermostat closes at 60C (140F). I have the thermostat zip tied to the lower absorber coil.
2 120mm Noctua NF-S12A FLX fans sit on top of the vent stack and 1 120mm fan is zip tied to the lower cover.
The fans get power from the fridge light circuit so they only come on if the fridge is on. The Noctua fans are almost silent and keep the fridge temp consistently at 1C (34F). The freezer keeps ice cream hard.
Without the fan setup, the fridge temps varied wildly and took forever to cool down. The freezer would not keep ice cream frozen, especially in hot southern climates.
