i wouldnt say it would be crap.. but on reality... what style of beer are you making and what yeast are you using?
I do know that there are some beers out there that require "warm" fermenting tempeartures to get the desired taste off hand i cant think of them, but they are more common than you think.
If it was a high OG, it might have alot of HOT alcohol flavors/feeling to it... (not 100% that this is true)
