The way I see it, its not really a hot card, it just has a weak reference cooler (allegedly the 7970 cooler repackaged), power consumption wise it's almost on par with the GTX690 however it's not *that* far ahead of the 7970GE/Titan (about ~30w), and when you consider that the hotter a GPU runs the more energy it consumes, if it had a better cooler it would probably be much closer to the 7970GE/Titan.
All in all I say it's not a lava GPU issue it's a weaksauce reference cooler issue and the Windforce/ACX/Lightning/etc models should fare a lot better on temps, noise and overclocking potential.
