You are probably correct, the middle temp may represent a sensor that is not recognized, but the other readings seem normal. > I started to trust mbmon, and i think the 1st temp must be motherboard, while the 3rd CPU, > and indeed the first value varies betaeen 41-42 degrees, and the third value from 39, (~ 100% idle) > to 45 (0% idle).

For stressing the machine, try math/mprime in torture mode. Watch the temperatures and make sure you leave it running for a couple of hours and you don't get any errors. Usually, if you have a termperature problem it will bail out in half an hour or less.
