Product: HP 470 G7

My wife has a HP 470 G7 notebook for work (Intel Core i7-10510U). It's been having a consistent random core temp spike of 100 C and sometimes shuts down due to the spike in temperature. I've been having her monitor the temps with Core Temp. Nothing that is being done on this computer even comes close to putting any strenuous load on the CPU as it's used mostly for typing documents (yes, overkill I agree). I've disassembled it, cleaned it, replaced the fan and thermal paste. The fins and all air intake holes are completely clean as is the fan. I first used Zalman STC7 paste, but after that made no difference I cleaned it off and applied Cooler Master CryoFuze. After that still made no difference I replaced with fan with a new one identical to the original. The temp still seems to be spiking to 100 C. The PC receives proper ventilation, but that doesn't seem to make any difference.

Any idea why the temp is spiking and overheating like this? Anything else I can try to remedy the issue? I'm no stranger or novice to repairing computers, but this has me stumped.
