I just bought the LG still air incubator. I have 14 e-ggs in there now and will see this hatch to whatever end with the incubator as a still air. After reading several posts and other online sources and dealing with temperature variation in my own setup I want to add the circulating fan. My question for those people who have this bator is if the fan made for it is special in someway, or can I use some form of a computer cooling fan? The computer fan would be cheaper and more attainable (the LG fan is around $40 and would have to be bought online), but I don't want to miss having a necessary feature the LG fan may have. Is the LG fan (or any circulating setup) wired in a way that it only comes on when the heating element is on or does it run constantly? Thanks for your help!
