Hm, I'm not shure about the notebook processors, but on my quad-core
Q6600 I see the following which is OK, I think


system idling along:

>-331: envstat 
                       Current  CritMax  CritMin  CritCap     Unit
  cpu0 temperature:     38.000                                degC
  cpu1 temperature:     39.000                                degC
  cpu2 temperature:     32.000                                degC
  cpu3 temperature:     36.000

and after a little workout:

>-335: envstat 
                       Current  CritMax  CritMin  CritCap     Unit
  cpu0 temperature:     43.000                                degC
  cpu1 temperature:     43.000                                degC
  cpu2 temperature:     35.000                                degC
  cpu3 temperature:     39.000
