Cpu and gpu temp

English Applications
1

Greetings everyone.

I would like to ask you if you know a program that can show the current cpu’s and gpu’s temperatures.

I would like to thank you in advance
Regards
Alex

you need to have installed sensors and libsensors4 (I believe) and the a program to display the data generated - I use gKrellm but there are other apps that display the data such as conky, various plasmoids (KDE) and computertemp (Gnome)

Thanks a lot . I tried syhstem monitod widget in Kde.
First thing is that gives me temperatures in Farad and not in celcius. Moreover it doesnot say if the temperature is from cpu or gpu.

There are four temperatures depicted
like

  1. lmsensors/acpitz/temp2
  2. lmsensors/acpitz/temp1
  3. acpi/thermal_zone/TZS1/temperature
  4. acpi/thermal_zone/TSZ0/temperature

Don’t know what cpu, but in a terminal as normal user, try command line: acpi -V

The result should include a cpu temp reading.

those are cpu temps, I assume you have a dual core therefore there are 2 temps but I forget the reason for the 2 diff sets of results (might just be duplicates as “acpitz” sounds a lot like “acpi/thermal_zone”

just type: sensors

at the bottom you’ll see:

CPU Temperature: +40.5°C (high = +60.0°C, crit = +95.0°C)
MB Temperature: +39.0°C (high = +45.0°C, crit = +95.0°C)

for gpu you might need a different widget that displays gpu - try System Monitor KDE-Look.org or Yasp-Scripted (Systemmonitor) v1.0.6 KDE-Look.org

If you have an nVidia GPU, installing the nVidia configuration software (I have both the regular and “dock” installed) will display GPU temp (and suggest what is the normal range).

Other GPU OEM may similarly provide software.

Don’t know what cpu, but in a terminal as normal user, try command line: acpi -V

11.3: sensors command works, but

vodoo@myhost:~> acpi -V -c
No support for device type: battery
No support for device type: thermal
No support for device type: ac_adapter

?

From my notebook:

     Battery 1: charged, 97%
     Thermal 1: ok, 35.0 degrees C
  AC Adapter 1: on-line

Oops, my bad recall, thought it gave temp result on desktop PC, but same “No support for” result also on mine. In any case, OP didn’t specify machine type.

hi,

sensors-detect is a script that will help you loading needed modules. so as root run:

sensors-detect

and answer every question with yes.

then restart, and try the command

sensors

post the output of it.

FYI - I just installed the sensors package and it resulted only in detecting the CPU temp sensor.
As noted earlier, on my machine I’ve installed the nVidia management software which is able to also detect and report GPU temp.

gkrellm is a must-have!

Just to ask this. How does sensor know about the crit value? IS this cpu specific specified by cpu manufacturer or is this laptop specified?

The cpu max temperature is cpu specific.

It has been the case that the limits and critical values were placed in a sensors config file by contributors to the lm-sensors project, who obtained the info from manufacturers’ data sheets. Now, in some cases it probably comes from ACPI and the machines BIOS, but to be sure check out that link to lm-sensors website.
