At this time - no. We wait adding support of Fintek F71869FG chip (which 
is in Hans TODO list).
Anyway, I think it is not root of problem, because my system is fanless.

If I run (after reboot), for example, cpuburn - and run commands, liste 
above, I have got same results - coretemp get values, that about 2 time 
more.

No.
