I have I big cooler bator hold about 40-50 eggs. I was worried my computer fan wasn't big enough which it probly is. I always go over board my wife says.
But I had one of those light sockets you screw in were the bulb goes it has a plug in too. So when the light kicks on it circulates the air to put the heat evenly i hope. So I seen a small fan at walmart for 5 bucks about 6 inches round and that does a awesome job better than the computer fan which is the bib one too.Just wanted to share Hope this helps somebody
