Hi Rudolf !
Thanks a lot for your answer !
You'll find enclosed the dsdt.bin and cpuinfo files and my comments inline :

No, no the discrepancies between the two core temps, and the temp seen 
by the mobo regarding the CPU temp. it goes from 13 to 40 ?C depending 
which way you use to find it...

This is low regarding BIOS readings : When the CPU is at 28?C the mobo 
is about 31 ?C for the BIOS. (BTW I've the latest BIOS :  Rev 0603)
