Strange.

emerge sys-apps/lm_sensors, run 'sensors-detect', and hopefully the
'sensors' command will show you the fan speeds and temperatures then. And
maybe the output makes sense. Here it does that only partially, this is
what it looks like:

                       (crit = +70.0°C, hyst = +67.0°C)
