Thanks John. I added pics.
Is there a reason you placed thermal switch at bottom of refer on absorber pipes instead of up top closer to fan on the upper tubes? I thought the upper areas were the hottest?
Since I have the OEM fan which is about 1'-2' below yours, which is at roof vent, I will add the two fans down below just inside the bottom vent just below absorber tubes, horizontally mounted, pointing upwards. These fans (similar to Titan 90mm fans) have a wire probe as a thermostat. Where should this probe be mounted?
The fans have a wired remote that controls speed and also has auto/manual modes so speed can be reduced if fans are working too good and refer temps are too low. I live and camp in SoCal (where it can get HOT and mostly camp in warm areas, so having refer temps too low may be a pipe dream, but definitely welcomed!!
Since with the above mentioned wiring method, what would be the efficiency/advantage or disadvantage of having two lower fans NOT in thermostat synch with the solo upper fan?
