Well I finally decided to try to control my fermentation temps with a swamp cooler. The other day I brewed a pale ale with US-05 and put 'er in the cooler. I've been switching out 1/2 gallon ice jugs every 12 hours. I checked the temp about 2 hours after the last switch and it is running at 55 degrees! What are the consequences of fermenting US-05 at these temps? Am I stressing the yeast too much? Am I going to get off-flavors? Thanks!
