This is not based on any research or objective information, only my personal findings. I usually ferment at the cooler side (about 65-68 for WLP001), then take the carboy out of temp control after bubbling stops. In the winter at my house, this is about 66-68 degrees. But in the summer, ambient temp is 76-78 degrees. I will keep the carboy at that temp for anywhere from 2 to 10 days, depending on how long fermentation took. Given that information, I have not tasted any of the off-flavors that are typical of a hot ferment.
Again, this is just anecdotal data.
