As mentioned in my post, I did change the thermal paste already. I also already did CPU stress-tests, with OCCT, AVX2, and Core Cycler with no issues. I am not sure another test with y-cruncher would tell me something I don't realdy know.

I already lowered the CPU maximum power state for 99% for what its worth. Still crashes.

Hey,
So I've just tried to run the Intel Processor Diagnostic Tool and it all passed.
Sadly I cannot turn off XMP on my Computer as ACER or Intel, I don't know which one, won't allow my computer model to play with the BIOS menu too much.

The temp spike is suspicious but do note that the crash has happened recently with temperatures of 70 degrees, which is a normal temperature mid game.
