So i've been running 2 7970 lightnings and I had a huge iverheat issue! Unless I have vsync enable my top card would easily make it over 90 celcius!! Out of boredom I switched cards, xfire bridge, and took both of the gpu reactors off to see what would happen! And to my surprise now the top card(after swap) hasent gotten over 56 celcius (with vsync) Does that mean I have a bad card? I know my case isnt the best airflow out there but is really good at it!
