hey shake -
your temp problem in the new box is the oscillating fan. those cpu fans work great, when they don't have to move already-moving air. if you can get by without the fan in there, do it. otherwise, you'll have to reconfigure its location, since you already have the exhausts in place.
another tip for temp control: intake at least 2x as big as exhaust. i'd do 3x or 4x with the pantyhose though.

everything is looking good, bud. that hermie saddens me. if you pick up some butane or acetone, you could salvage it in some hash.

best of luck!
