If you do a search for temp contol or swamp coolers you will see some off the ingenious ways we've come up with...mine's not too ingenuis, it's just a rubbermade bin that can hold 2 5 gallon buckets, or any other combination...plus t-shirts to work as water wicks.
It can work in several combinations of fermenters.
I figured out with the 3 gallon square sided betterbottles I could get between 6 and 8 of those bad boys in there.
I've gotten down to about 57 in the heat of summer with that setup.
But don't count that beer out, even if it doesn't taste good after 3 weeks in the bottle, read what happened to my last year's "Spring heatwave" beer.
Not to mention the followup to it in the thread...http://www.homebrewtalk.com/862209-post48.html
