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?

I had a similar problem. Mine were off by 4 to 5 degrees. I used the same paste as you, but went one step further and did one of the inside heatsinks, before I ran out paste. I have more on the way. The inside heatsinks have hundreds of thermal paste dots over the whole surface, so it was a challenge to try and spread the paste around.
The results were that the blades are now within 2 degrees of each other, but the unit still struggles to pull 440gh/s, drops over time, and can't be overclocked without lower hash rates and Xs and -s showing up.
After the paste gets here, I will redo the other blade and see if it helps at all.
On a side note, I have also installed heatsinks on the R47s and the little black chips above them, and it did not seem to help at all. At this point I'm a little nervous about them being in there.

Thanks. Seems you have a similar problem as I do, just with a smaller temp diff. My problematic unit also doesn't OC well. I actually ran out of paste after just doing all the chips. Let me know if you see any improvement from repasting the backside of the other blade. Might get new paste and try that as well.

If you say the temps dropped but you didn't see any improvement in speed it might not be the source of the problem actually.
