Brewed an imperial stout and the ambient temp for fermenter high 60s, inside fermenter it’s at 82!!! Been that way for 14 hours, already chugged from 1.117 down to 1.062.
If I were you I'd get that temperature down to the 60s. Very warm fermentations can create off flavors. While there are exceptions that need a warm fermentation (a Saison or maybe Farmhouse Ale), generally you want your fermenation to be within the temperature range noted by the manufacturer of the yeast.
If you don't have a fermentation chamber, you can use a swamp cooler arrangement. Get a turkey pan from the dollar store, put the fermenter in it, add water to just about overflowing. Put an old t-shirt over the top and let it drape into the water. It will saturate and the evaporation will help cool the fermenter.
You can also add ice to the water as one way to cool it in a hurry. I'd probably be trying that.
I'd also probably pour a little water over the upper part too to keep it wet. Or put ice cubes under the shirt so when they melted they'd make the t-shirt wet.
