Hi i have x1600xt, and cannot have my side panel on my case without getting artifacts and vpu failures while in game. ive kept a temp log running in the background while i play a game with the case on, and off off the max temp gets to be about 60c lowest is 43c, no artifacts or vpu failure. witht he case closed it quickly rises to 66c and then vpu errors and it goes to 50-55c and instantly back up to 64+. i want to be able to close my case and OC, if i OC i cant close the case. it has an arctic silencer on it, and the same thermal compound i use on my cpu. my cpu never get hotter then 40c on air with arctic alpine 64. the side panel to my case has 140mm intake fan, with a cone that cups the cpu fan perfectly and my cpu doesnt get any hotter with side panel on. i have an 80mm exaust fan on the rear panel of the case. i have all removed all of the PCI slot back metal panels. What else can be done to help cool my video card core?
