CPU temperature and thermal output help


Hello everybody,

could someone please help me understand the output of the:

"cat /proc/acpi/ibm/thermal"
temperatures: 51 0 48 3 0 0 32 0 53 59 88 48 53 0 0 0

or point to a reference of this output?

I am running slackware 14.1 on a thinkpad edge 11 with i3 and 4GB ram. The temperatures measured by the simple CPU sensor are between 45 to 58 (sometimes even 60) Celsius (with moderate activity). Is this normal or I should worry about the temperature?

They say that the first value is always the CPU and that the remaining values depend on the motherboard.
More, and only infos here.

Unfortunately, your specific model is not listed.

In any case putting a cooler under your laptop never hurts.

The core temperatures of Intel processors are monitored by the coretemp kernel module.
If you do 'find /sys -name "temp?_input' then you should get the location of the various temperature monitor inputs on your system.
Hopefully you will also see in the same directory containing the temp?_input file other files temp?_label, temp?_crit and temp?_crit_alarm.
For further details see /usr/src/linux/Documentation/hwmon/coretemp
Also, according to that document, a 32nm i3 processor has a TjMax(C) of 90 or greater, so 60 Celsius is not a concern.
