I suppose then that immediately after shutdown and entering bios (let's
say after 1 minute after launching sensosrs) temp. in BIOS will be a
little higher then befoure running linux. And it is not.

Besides I don't know which sensor Temp2 indicates (why it does not
change) - I'm pretty sure it is not CPU sensor. How can I check/change

I'll do my best.
