You can't really compare heat of two cards unless you're trying them both in the same system. Keep in mind, a smaller case will run hotter, more/less components will add more heat to the cards. I do however know, my 270x idles at 18-20 degrees fully stock, and ramps up to about 50 degrees. At the same time though, I have a water cooled CPU, a full tower and two 140mm fans blowing air into the case. Its actually cooler in the case than it is in the room.

Obviously others would have drastic changes in temps, depending on how their systems are built. So like I said, its not really fair to go comparing heat output between your gpus when chances are your systems are completely different
