Here's the output of sensors command:

Adapter: ISA adapter
fan1:        3414 RPM

Adapter: ISA adapter
Physical id 0:  +50.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:         +47.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:         +49.0°C  (high = +86.0°C, crit = +100.0°C)

Adapter: Virtual device
temp1:        +49.0°C  (crit = +99.0°C)

What is the Physical id 0 device, and how does the virtual device works here? Where does the data come from?

Did you start # sensors-detect before that? – diffycat May 1 '12 at 13:59
