Not sure if I understand exactly what component it is that is getting to 123 degrees in a second, is it the motherboard chipset or a core on the CPU? Either way such a fast rise to 123 degrees sounds like a false reading to me, have you tried checking your temps with some other software and possibly also in the bios? If it is the CPU hitting those temps it is almost certainly a false positive and the fault of the program you are using, the chipset on x79 motherboards can get quite hot, but I doubt they could legitimately hit 123 degrees and not shut down.
