Here's a couple of pics showing the thermocouple and turner shelves. The thermocouple is about 3" from the heating element, and I did have it centered exactly between the 2 fans, but I run both fans during the full ~23 day duration, and cut the right one off on hatch day. With the sensor favoring right in front of the left fan discharge, it picks up the direct heat when the element cycles. I don't run both fans while hatching even though I run super-high humidity because I found it was playing a factor in some of the shrink wrapping I was having (because of the false-back design which forces the air to flow down across the eggs to the return opening at the bottom of the false-back).
