Hi!
Arg, I actually wanted to continue writing my last email later, but pressed
the send button by accident...

No they dont. eg:
VCore: +1.23 V (min = +0.00 V, max = +4.08 V)
Bios shows 1.35V, so clearly the voltages are off.
Here are the dumps:

Yes, looks better now. Maybe you want to lower the fan limits, as well?
fan1: 830 RPM (min = 3245 RPM) ALARM
fan2: 0 RPM (min = 3245 RPM) ALARM
fan3: 782 RPM (min = 0 RPM)

Actually I never searched for AMD docs, but in the AM2 section doc 33425
refers to 31117 and 31119.

It is this one: http://www.arctic-cooling.com/cpu2.php?idx=80&data=2&disc=, so
the fan should be quite big, that's what makes me wonder.

True, but I probably can'T fix the broken hw anymore. ;-)
