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:
