I had an area that size and did have a few issues cooling it, although my plants seemed to do ok with temps around 85 or 86. I had two computer fans blowing out air, that were both rated at 45cfm I believe, but I had the air routed through some pipes into a different sealed compartment to blow out for light concerns. If you aren't worried about the light escape from the fans then venting the room itself with 2 or 3 fans ought to do the trick. If you get a voltage adapter from Radio Shack, or Frys, you can splice all the power cords from the multiple fans on to it and just plug the adapter into the wall. There are also a few computer fans that have variable speed settings on a switch on the cord, which may be useful to you as well. Happy Growing.
