I've run overclocked 7970s for over a year and know it isn't that hard to dial in a good heat/performance sweet spot. And that's (mostly) with stock air cooling!
Wow you really do come out with some sh1t don't you. ha ha ha ha lol yes it's just the same as your gpu. Over a year? I mean overclocking your card for 6months is amazingly but you did it for a whole year! congrats. looks like we have a real pro here guys. :-D
give eASIC a call and give them some tips
