sorry for being such a newbie but what is stock cooling and how do you open the case for a 7990? I have two xfx 7990 but temps gets to as high as 95 degree C with a hash rate of around 500MH/s.

Can someone please help me with the best configuration to maximize hashing power.....I did pay big $$$ to get them..thanks

Stock cooling is the cooling already on the card. As for people referring to open case they generally mean taking the side(s) off of the computer case. For dual 7990 you also want a big fan aimed into the general pc case, 500Mhash sounds like they're throttling back due to getting too hot!

Thanks Tom_o!!! Do I still need to use a crossfire for 2 xfx 7990? Also, just wondering what type of fans are the best to cool down the cards?
