At least on Debian Wheezy with 3.x kernel sensors doesn't work properly.
How it looks:Edit
$ sensors k10temp-pci-00c3 Adapter: PCI adapter CPU Temp: +32.5°C (high = +70.0°C) (crit = +100.0°C, hyst = +95.0°C)
Ok, let's fix it for debian.Edit
- Compile and install https://github.com/fetzerch/hp-n54l-drivers
- If sensors output is still too small then check if sp5100_tco is loaded (lsmod | grep sp5100). Try to unload module (rmmod sp5100_tco) or blacklist it. Temperature (i2c-piix) or watchdog (sp5100_tco), your choice. More info
- Add this ppa and install hp-n54l-dkms package.
