Verify that you have a directory in /sys/class/hwmon/ (probably it is
/sys/class/hwmon/hwmon0/). You can actually view the plain-text data
read from your chip in /sys/class/hwmon/hwmon0/device/.

Assuming that's all working, sensors just needs you to edit
/etc/sensors.conf and set up the motherboard-specific parameters, such
as what fans are really present, what the voltage measurements mean,
etc. Your BIOS setup should be useful in getting those numbers right.

Good luck!
