I have asus p8z68 motherboard, i get abnormal results when i use Probe 2 with HWiNFO64 monitoring software. It looks very similar i got warnings like:
6:40 CPU temp -120
6:40 CPU temp 40 (normal)
Maybe you are experiencing something similar, i think that Probe 2 makes mistakes when used with other monitoring programs.

temp can't go this far !
clear your old reports and run probe 2 (singly) for 12h and then go and check the errors (if any error available )...
i just running the prob 2 (whit other apps like CPU-z this app can shown wrong things) and got this errors in idle !

[10/20/2012 at 09:29 pm] MotherBoard -92.0 Abnormal
[10/20/2012 at 09:29 pm] MotherBoard 33.0 Normal
[10/19/2012 at 02:29 am] Vcore 0.000 Abnormal
[10/19/2012 at 02:29 am] Vcore 1.208 Normal
but only when things like HWiNFO64 are on at the same time, when not everything is normal. Because of that i think that Probe 2 makes false warnings, also abnormalities last only minimim amount of time.
