Fermentation has slowed but the gravity is still WAY high. Be careful you don't cool it too much and send all your yeast to sleep before the work is done. You could end up with a very sweet beer.
+1. My advice would be to leave it at 75-80F at this point. Whatever off flavors could have been avoided have probably already formed. Also, as said above, by putting your beer in a cooler enviornment it can trick your yeast into thinking it's time to go to sleep.
