MSI GS66 throttling at extremely low temps, fan shoots up to max RPM until system reboot

I have a 1.5 year old GS66 stealth that has been having throttling issues when gaming, about 10 minutes into a session the fans will blast up to their max RPM and the system will become extremely sluggish (cpu will become locked at 800mhz) until I restart it.

I suspect it is an issue with BD PROCHOT via some debugging with throttle stop, but the issue persists even if I disable BD PROCHOT, the flags in throttle stop that come up are PL2 and BD PROCHOT when the throttling issue happens.

It is interesting to note that when the throttling happens with BD PROCHOT disabled, the CPU is throttled to 2500 mhz instead of 800 mhz, but I really have no idea what the issue is.
