3'x4'6"x1'6" Box With CFLs Help Heat

Let me start by declaring that I'm an immense noob, long time smoker, first time grower, and I'm relatively handy I've worked in the trades for a year and a half now so I don't consider myself completely handy-inept anymore, just a background. Okay here goes:

I just finished all my wiring and lighting, I've converted an old dresser into a grow box(3'x4'6"x1'6"), painted the inside a matte white, I've had it plugged in for like 30 minutes now, just doing a dry run before i move my plant in, and so far it seems to be kicking out a lot of heat. I'm just opening the door periodically (i have no air flow yet, I was planning on installing a 4" duct out the back with a duct fan, but that's why I'm here so I know which one to buy). I was under the impression that cfls created very little heat but this set up is making a noticeable amount.
I'm running 2 x 40w 4000K bulbs, 4x 23w 2700K bulbs, and 2 x 23w 4000k bulbs.
It's my first plant, she's been growing on a shelf in the sun, and I've had her outside on the porch for a week now but last night some prick squirrel decided to dig in her pot and I found her laying on her side. I am PISSED, so I've vowed to finish the box today. Any advice on what to do or if the heat is okay?

(I ordered a thermostat/hygrometer and it's in the mail but I won't have it for another week, other wise I'd tell you the current running temp).

Rip some of the fans out of your computer, hook them up to the corresponding plug adapter, and install them on your cab. LOL, or go to a computer repair shop (I've got 2 near me) and get some used ones for a few bucks.

heat is bad no more than 80 in there, drill some holes in the back at the bottom to let cool air in, when you install the fan it will suck the hot out and pull the cool in from the bottom holes.

So I've been monitoring (basically watching the clock change) for the last hour keeping an eye on the temp in the box, by the feel of it (and I'll get a thermostat in the mail soon, it's en route) it's about 8-85 in there, so hopefully that's okay for a few days, I'm mostly worried about my cfls overheating and starting a fire or something, you know, I live with roommates that don't know about this recent project of mine, and while it's mostly a hobby, I really want some weed out of this because I haven't smoked in a month because my neck of the woods has recently dried up and a couple of my reliable dealers moved away, and the rest quit or what not, so I'm kinda going to have a productive period then when "Terri" my plant (and her clone Sherri (Simpsons)) flower I'll be happy to have some bud to smoke again after harvest
