Similar experience with an Asus motherboard. With their automatic tuning, instability leading to compiler crashes. Had to manually set the BIOS for sanity.
I believe the problems are compounded by the way their SuperIO controls the cooler, because the crashes were associated with temperature excursions to 100C. It's too slow to ramp up and too quick to ramp down. It is possible to tune this from userspace under Linux. But really the up ramp should be controlled by a leading indicator like the voltage regulator instead of a lagging indicator. Alternately the Linux p-state controller could anticipate the power levels and program a higher fan speed.
I'm dealing with this right now (Asus ROG Z790, 14900k, Noctua NH-D15). The stock fan curves seem to be ineffective and also annoying as they are hunting constantly. Single P core temps bounce around constantly causing the fans to be spastic.
I have read increasing the ramp up time would smooth out the fan behavior but your experience says this can cause processor fails.
Exact same setup, I'm afraid. Best solution I have been able to come up with is to read the datasheet of the SuperIO on that board and tune the hysteresis parameters from Linux after boot.
