Thought it might be interesting. Last night I assembled my new computer, installed, run and played Dayz for about 3 hours. Today in the morning installed HWMonitor of curiosity to have a look at temps - 100 degress Celsius on idle. Restart, checked in BIOS - the same.
Apparently I had not pushed well the heatsink push-pins. I know, a newbie job. The processor worked for hours w/o cooling, other than its own integrated heatsink. Replaced the heatsink, temperature is 35-40 degress, it is all right. I am happy the trottling is made so well - to limit the processor, without me even noticing - not a single crash or shutdown.
