Romain, Thanks for your feedback. The coretemp driver provides support for the on-die digital thermal sensor present in Intel Core and newer CPUs (according to coretemp manpage). I am using old Intel Pentium M processor( http://privatepaste.com/d107389cc1), so coretemp module can't help in my case. Regards, Nick
