Yeah that’s highly abnormal and it’s completely possible that you messed something up during the repasting, but it sounds like the issue was there before you did all that.
Looking at your specs, that https://www.amd.com/en/products/processors/laptop/ryzen/7000-series/amd-ryzen-5-7535hs.html is a roughly 50W CPU and has a tjmax of 95C. It could just be AMD doing AMD things, which wouldn’t surprise me.
Can you also verify that WoW is indeed using your RTX 4060 and not the built in AMD Radeon 660M iGPU? Within WoW, there is a setting to pick the graphics card: Pick the RTX one. iGPUs share the same die space with the CPU, so if the game is using the integrated card, it will also heat up the CPU as well. There is also a possibility that it could still potentially be doing some kind of hybrid thing as well, where it’s trying to utilize both cards at the same time.
