Well, not having access to a "Lab quality" temperature meter... I have simply used several commercially available thermometers and averaged the results.
Once that was done at idle and under load I "adjusted" my MBM5 software to compensate. As stated before the sensors on most motherboards are neither accurate or placed in very good spots.
I then remeasured my temps with the external thermometers (yes they had thermister probes) and verified that my MBM5 temps were within 1 degree C.
I will see if I can obtain a temp meter from the lab and bring it home to verify.
My ambient air temperatures in my apartment range from 21° C to 25° C this is also based on those same external thermometers.
I have not directly monitored the water temperature, so I guess I can't give numbers for that. :shrug:
If my methodology is flawed... please relate the proper proceedure for measuring these temps without a lab quality meter.
