ipmitool cpu temp

["michael" <michael@estone.ca>]

Hello,

Have an Intel S5000VSA board.
Here's the output from the ipmitool command:

# ipmitool sdr type temperature

Baseboard Temp   | 30h | ok  |  7.1 | 48 degrees C
P1 Therm Ctrl %  | C0h | ok  |  3.1 | 0 unspecified
P1 Therm Margin  | 99h | ok  |  3.1 | -34 degrees C
P2 Therm Margin  | 9Bh | ok  |  3.2 | -34 degrees C

What I don't understand is why the CPU temps are negative.
Can anyone shed some light on this?

If I work the CPU a little harder the temp will go up to about -28 degrees C.

Perhaps I just don't understand what a P1 Therm Margin is refering too.

Thanks,
Mike
