Recently, I have noticed my GPU temp is running in the high 70's when I play World of Tanks, when it used to run in the 60's. I changed the thermal paste and that helped for a little while but I am thinking that my paste is probably to old and need fresh paste. Having come to this conclusion, I am also looking at the fact that I may need to go ahead and replace all the thermal padding while I have the card broken down as well. So, I ordered some new Arctic Silver 5 paste a 50mm X 50mm X 1.5mm pad, like a dummy not realizing it wouldn't be enough. But, my question is how much padding and what thickness(s) do I need to do a complete thermal pad swap out on my card? Any information and assistance is greatly appreciated. While I could by a new card, I just hate to do that until I decide to build a new Mini ATX computer in the fall of this year. Thanks.
