Anyways I turned off the computer once temperature hit 65c from going up rapidly from around 35c.
Ryzen likes to report its temperature jump in spikes of +10 to +30°C depending on the kind of load and on the voltage. These are kind of overshots that report a higher temperature than what the CPU already reached.
Here is an example where lower
total CPU load and power draw lead to higher temperature increase (+20°C spike) likely due to a specific CPU instruction set being run.
So am I protected from CPU over temperature or not? I was in a clear case of going to a over temperature condition less than an hour ago and I do not know now.
The default Sense Skew BIOS settings will not allow your CPU to do a thermal shutdown, even when you completely disable all cooling. Instead you will likely rather run into a code 8 crash, which does not do a complete shutdown and keeps applying voltage to the CPU.
This temperature spikes may well be why Asus does the whole Sense Skew stuff to begin with. One big problem of those overshot spikes is that they can overshot X CPUs (+20°C) to throttling and even thermal shutdown territory even when the real CPU temperature isn't quite there yet.
This whole CPU temperature deal is utterly BS, if one is given a temperature it should be the temperature and no skew added to it. If AMD wanted a tighter lower temperature profile then they should have stated that for XMP. Utter chaos that skew temperature has caused users
If you want to use skew then for X CPUs I suggest 262 - 266 MI offset to keep a high headroom for overclocking, else just turn it off and be on the safe side as far as thermal shutdown (then happening earlier) is concerned.
