Anyone have experience with an S3 where chain #1 gets much hotter? I have a 40 degree temperature on chain #1 while chain #2 is only 32 degrees. The whole thing is a lot slower than the other S3 I have.

Have already tried removing all the thermal paste from the chips and applying arctic MX-2, but that didn't change anything. Does it also help to change the paste on the inside? What else is there to try?
