I just discovered something. The dead/sick card I told you some posts ago, it was running with 1500 rpm fan but the others were running about 2000-2500. I clicked the user define (on the right of FUN in afterburner. Now all my cards are running at about 2500 rpm fun and they all went about 10 degrees down! Did I do the right thing? The hottest card is now 65 degrees and others are only 55. And they are giving me 430 khs each. So can someone tell me if I clicked the wrong button or right button Or will I find my cards exploded and melted next morning I wake up?
Sounds like you might have found the cause of your problem. Keep a close eye on them over the next few days to be sure.
On a related note, CGWatcher will automatically lower your intensity if the temps get a little too high.
