The fan is to try to ensure that the temperature throughout the incubator is constant without dead spots. I use coke fridges as incubators, which are about 1.5m from floor to ceiling. Without the fan on you can get 2-3 degrees difference in temperature from bottom to top shelf. It is a little like the temperature gradient in a reptile cage. My fan also blows the air across water to maintain humidity.is air flow a big concern. I have been told to wire up a computer fan or something to circulate the air.
