thnx for replying, I think i have done nothing that overclock my card. It is al on standart values. Now in windows i have a temperture of 41/42 degrees when idle.
I have done a test with scan for artifacts, and when it's over like 2/3 minutes of scanning and hit the 69> degrees the problems begins for me. I have also tried to use the fixed percentage in fan control to 100% but when i hit the scan for artifacts button it still climbs in temperture with no reachable stable point.
I think myself that the problem is when it hit the 70 degrees it gives me problems.
But i'm no expert.
