So you have this same problem as reported on bugzilla. Feel free to add
a comment there, stating you have the same problem. I would like to see
the problem resolved.

Quite possibly in1 is VCore2. Edit /etc/sensors.conf, look for the
w83627thf-* section, and edit the labels as:
label in0 "VCore1"
label in1 "VCore2"
And comment out the "compute in1" line.
Might do the trick. More generally I invite you to search for hardware
monitoring data in the BIOS setup screens at boot time, write down
everything, and tweak /etc/sensors.conf accordingly. I usually helps.

I doubt that. 19.5 degrees is not much. I never saw a CPU running below
24 degrees - and it wasn't an Opteron. If Opertons can really run that
low, I'm going to buy one.

Unused, no. Unmonitored, quite possibly.

Gkrellm and sensors share the drivers, but sensors relies on libsensors
and sensors.conf, while gkrellm does its own confiugration stuff. This
explains the differences.
