Hi, I have a 780ti SC ACX edition gpu inside of a corsair 250d case(matx case) And when i start up a game in a matter of seconds to minutes the gpu will get up above 70c. And within another 10-15 minutes the computer will freeze. I have adjusted the fans on the gpu and it doesn't seem to help all that much. Could this be a problem with the gpu itself or could it be just overheating because its in a very compact case with little room to breath. Any help would be appreciated. Thanks.
