i didnt read through them all sorry but... u think maybe the mylar
and Styrofoam maybe the problem considering they are used to
keep heat in

like for a body going into hypothermia or when u want to keep ur
beer cold in a cooler
i have like 8 - 48 watt cfls and mine doesn't go over 82

and its sounds like ur intake and outtakes are setup right after
what every one else has said

but hey thats just my 2 cents
