Keep the fans pointed at the roots. The leaves can handle the heat without probs but the roots can not and should be kept below 70 degrees, 60 if possible. Plus it won't blow the leaves around as much which dehydrates them and causes more odor problems than if not disturbed. Also PH your water. It looks as though they have lost their entire lower canopy and it'll be working it's way up unless you fix it.
