It's a little warmer than usual in Massachusetts right now, and my basement (and my fermenting beer) is at about 80* F. I have 12 gallons of ESB in the tank right now. I'm using us05 ale yeast, and it's max temp in it's profile is 75*. There's no possibility of cooling the fermenter, it's too big. The fermentation seems to be going a little quickly, down from 1.051 to 1.012 in 2 days. Is the rapid fermentation due to the higher temperature, and if so should I be concerned? Or should I just relax because there's not much I can do about it?
