Because the fan speed has everything to do with how stable the temperatures are shelf to shelf, that and our fan is a lot larger bathroom ceiling fan and had to be slowed down.Originally Posted by llovelace
If the fan runs too fast it makes the bottom of the incubator hotter than the top
Micro-managing the fan lets me dial in all 3 shelves to the same temperature.
We fought shelf to shelf temperature differences until plugging the fan into a rheostat.
Our incubator is a 24 cubic ft. true cooler and for now we use 3 shelves that will hold six 7qt tubs. To get the same temperatures on all three shelves we just move the fan speed up and down until the temps are equal on all shelves.
Bathroom ceiling fan plugged right into a zoo-med rheostat facing backwards to blow against the back of the inc.
Sorry, I do not know how to do the same with a computer fan
