[resolved] lm_sensors reports extremely low voltage on +2.5V

Hi all.

I recently discovered that my old motherboard has support for I2C (for use with hardware sensors). Curious about my CPU temperature and fan speed, I installed lm_sensors from Portage. I then ran `sensors-detect`as root, scanning all busses and devices. Then I ran `sensors -s` as the script suggested. Now when I run `sensors` I see

lm_sensors gives some wicked results - I wouldnt worry about it.

here's mine:

Ok. Thanks.

It's been awhile, but iirc...

'lm _sensors' doesn't just display the data it reads off the chips,
'cause that data wouldn't make any sense. It converts them with a
certain amount of "factoring", that maybe based on published data
from the harware manufacturers involved or educated guesses.

Your system might_be/probably_is different from the system that
was used to derive the "factoring".

_Possibly_, you might be able to check this by letting your system
run for some period of time, with just the one full screen console
(runlevel 3) running, to get the system to stabilize. After that period of
time run 'sensors' and copy the data down.

Then reboot into the bios, and check the temps after some period of time.
If there's a big difference you could go into that lm_sensors config file
and make some adjustments, or.... you could google... maybe someone
else has already done the work.

YMMV'
