X399 - 1900x temperature?

I'm a little confused and need some help...

According to AMD's website the Threadripper max temp should be 68.c, I have heard that AMD enforces a policy of a 27.c offset called tCtl which I believe is applied to tDie so if the actual maximum tDie is 95.c this would mean that either thermal throttling or thermal shutdown would occur at ( 95 -27.c ) = 68.c

So my main question is would a sustained temperature of say 72.c under full load being reported for 24 hours cause damage? I also note that my mobo manufacturer ASUS has set a temperature of 75.c I believe it is before things start to happen ( I don't know if this is a throttling temp or a shutdown temp ).

Basically what I want to know is what a proper temperature range for operating the CPU is and what sort of temperature is the danger point.

Thanks in advance.
