That and the yeast will ALWAYS throw less off flavors the more stable the temperature. Yeast do not like rapid temperature fluctuations. The swamp cooler will help you get the temp you need and minimize the swings.
Hooking a temp controller up to a mini fridge was the best thing I ever did for my beer.
