Hi, a few months ago I posted this thread as I was having problems with my GPU's cooler http://forums.guru3d.com/showthread.php?t=397021 . I went ahead and RMA'd the card and EVGA did a Cross-Ship RMA. Today I received the replacement card and when I first ran Valley, I noticed lower clocks than usual. My original card would boost to 1137 MHz at stock without any overclock. The new card only hits 1084 MHz. The next thing I noticed was that the new card ran about 5 degrees cooler. I can manually set the overclock to put me back at the stock boost of the old card and appear to have no problems and the card is still 5 degrees cooler. Now here is where I have the question. I talked to EVGA and was told since it was an issue with the cooler I could swap the cooler off of the new card and put it on my old one since the old one was boosting higher. I'm not sure if I should do that, the new card appears to run cooler even after I set the clock speed back to where the original card was. Maybe the old card could overclock a hair better (never went higher than 1189MHz) but I never really pushed the old card due to temps. What do you, the wise members here, suggest I do?
