So umm, first I'll just say hi, because I'm new on these forums, although I've been coming to this place for reviews for a fairly long time. So yeah, I bought these 2 5770's like a week ago, and today I decided it was time for some oc'ing. Downloaded Afterburner, installed it + Kombustion. Decided to run the Kombustion stability test with stock clocks first to see what the temps were like (I've overclocked before, every card I've ever owned actually). So I check out temps in kombustion and it says the top card is hitting like 80°C + while the bottom card remains below between 60 and 70°C. Isn't the top card a little too hot? Or is this normal? Will the temp difference go up once I start overclocking or will it remain the same? Is it safe for these cards? and what I a safe range of temps? Thanks in advance.
