Only thing I could think would be to invest in a window or portable a/c unit. Aside from A/C i don't know of anything else you could do....?

Mine get to 95 sometimes during the day, I just make sure I have a lot of air movement/circulation. They will grow slower than normal. My plants at three weeks look like others at two weeks.
I have the same problem man. I can't get temps below 90 in my box. Very unfortunate, just try to lower the temp in the room outside the box. My apt is set up with a hotel style AC unit which is at the farthest point away from my box in the apt (very small apt) if I turn my AC off and the temp in the apt goes up, then the temp in my box will soar.
You can however add a homemade CO2 dispenser, a high level of CO2 in your box will help to offset the negatives of the high temps.

my dog farts @ greater than 85cfm......
you need more rapid air exchanging, get a bigger fan!, like 120+ cfm......

I would go to a pawn shop, look on craigslist. Think outside the box for an A/C man. My temps were getting to 100 and I found a cheap A/C for $30. Dropped my temps right down to 77. And My room is 26' by 16'.

yup, my cab is 2'x3'x5' and I have a 400CFM exhaust fan on full. Of course it's much less than that because it's hooked up to a cooltube and filter but it gets the job done. 85CFM is less than most 120mm PC fans lol
