hi guys,
I was just wondering how you manage to keep your cards this cool?!
I got two xfx 5870  running at 860/300 stock voltage and I can´t get the temperature down.
My temperature after a day of mining is between 83C - 86C the cards fans are working their asses of at 100%
How can that be? This is my current setup:

Maybe you got some tips?

Thank you!
