We run ours during the day at about 77 degrees and as soon as it starts to cool down outside we turn it off and open windows and fantastic fan. We do have trees to either side so only get an hour or two of sun straight up. So it Really helps to keep our heat gain down. Also use a couple small fans inside to move air. Of course we are in southern Idaho now, so that helps also! In the am we close up before it gets warmer outside than in, so we are not starting the day from behind!
