Sensors Explanations

Hello,
I am trying to get some information from the sensors on my pc. But i get confuse with what i get.
I don t know where to find out which sensors watches what..
I use "sensors" under ubuntu 10.10.
Here is the result of the cmd line sudo sensors.
the temp 3 indicates 79�C which makes me wonder what it observes. And globally what do the temp lines exactly watch

I tried to look into the /etc/sensors.conf file and got those line

it didn't help me much and the label shown suit better to Winbond W83792AD/D section of the same file.. but the first line
of the result indicates it8720-isa-0228.

If someone could help me on the matter, I would be grateful :slight_smile:
