my incubator is a typical DIY minifridge setup. 2ft of 11in flexwatt taped down the back. all spare room is filled with water bottles and hot/cold gel packs.. fan mounted on the front door pointed at the back wall helps to create a circular air motion... idk haha i opened the door put my hand on the fan and it was burning hot therefore acting like a heat source in the closed incubator.. maybe a bad fan? idk

this is the fan http://www.radioshack.com/product/in...ductId=2102825

on a side note... i decided to leave it setup the way it has been running for months and months now and its doing just fine. temps inside the egg box are holding 87.8-88.2
