Hello, I replaced the thermal pads now with 3.0 mm Thermalright Odyssey pads and memory temp went down from over 110C to 84C.
But the problem is, that now the other (first) temp is up 88C in about 5 seconds after starting t-rex miner. What is the problem now? I also replaced the thermal paste directly on the chip, like shown in that video:

Yes, this could be the problem. Also make sure none of your pads moved or folded when you were putting it back together. Your new temps are more concerning than your old temps to be honest. I would definitely crack it back open and have another look. As others have mentioned, your over/underclock settings have a lot to do with power usage and hashrate. I'd advise you to do some googling and read what settings other people are using to get their hashrate. You may find that you're able to increase your hashrate and decrease temps/power usage by fiddling with some adjustments on your settings. Hope that helps. Good luck!
