Hmm, doesn't seem to work, after loading jc43, I don't see anything new 
appearing in sensors output.

Ah, that makes sense, even if it's interesting that the PCH Chip is so 
much hotter than the CPU, but then it doesn't have a fan attached to it 
and still enough work, so sounds reasonable. And "PECI Agent 0" being 
similar to the values from coretemp is also probably reasonable, as IIRC 
PECI means something similar to that, right?

The i7-2600K is just an incredibly cool CPU, I guess. ;-)
