How to get CPU temperature in linux

tduglas · 11-10-2007, 04:28 PM

Are there any libraries which allow me to get cpu temperature by simple library call?

Can i programmatically measure the heat dissipatiotion by the cpu?

Yes to your first question - have a look at http://www.lm-sensors.org/ (although Debian probably provides packages). I'm not sure about the second question...

If your machine uses ACPI...

cat /proc/acpi/thermal_zone/THM0/temperature

Cheers,

i can only move to /proc/acpi/thermal_zone/.

Writting the man page for that would be way too complicated

On my 2010 Debian Lenny system, the path is:

proc/acpi/thermal_zone/THRM/temperature

A clear case of the act of measuring affecting the result, unless your finger has a specific heat of 0.

Code:

acpi -t

Thx! Also i'll tell U, that on my OpenSusu 11.1 works both:
cat /proc/acpi/thermal_zone/THRM/temperature
acpi -t

Is that a joke or spam? Do you realize this thread is a few months old?

As /proc is being deprecated you can check your system's temp with acpi -t as it's been said or with "cat /sys/bus/acpi/devices/LNXTHERM\:00/thermal_zone/temp". Result is given in mºC (The thermometer you might be interested in might not be in that exact path).

According to your kernel version you are still using Debian Etch. Etch is not supported anymore (no security updates) since February 2010. I would strongly recommend to upgrade at least to Lenny, better to Squeeze.

Hi,

while this is good advice I just want to point out that this is a resurrected thread that was started in 2007 ...
