The first shot is the outside of my box when it's all closed up. I pulled the box out a bit, sealed around the fan with a blue towl, cut a few small holes in the bottom and created a vacume that sucks out the heat. When I put my hand up to the whole I can really feel the air getting sucked in nicely:thumbsup:

I ended up placing some emergency blanket on the two walls. I don't really like having the bulbs sit against the cardboard even if they really don't get all that hot. Since I've read that heatblanket is a semi-sort-of decent reflector, thought better safe than sorry.
