thanks KP. i have a 465 cfm exhaust and a regular oscilating fan in a closet thats about 130 cubic feet. i can't seem to get the temps much lower. I managed to achieve a steady 83 now, but with summer coming i'm a little woorried i wont be able to keep it cool enough. Any recommendations? i dont really want to spend the money on a portable A/c unit. is there nothing else that can help my situation?
