A water bath will REALLY help! I fill up a tall cooler, and put the fermenter in that, and then add water to that to the level of the beer. It really helps reduce big temperature fluctuations, since takes a long time for that much liquid to change temperature.
Unfortunately, big temperature fluctuations usually have a detrimental impact on the flavor of the beer.
