Okay I have psensor installed, I installed lm-sensor and some other related packages, I ran sensors-detect and didn't come up with anything. It is only showing my HDDs, and my CPU usage not temperatures or anything like that.


processor   : 3
vendor_id   : AuthenticAMD
cpu family  : 16
model       : 4
model name  : AMD Phenom(tm) II X4 920 Processor


Handle 0x0001, DMI type 1, 27 bytes

Product Name: GA-MA78GM-US2H

I'm pretty new to temperature sensors in linux, let alone fan sensors (which I would like too). What am I doing wrong?


AMD 10h k10temp kernel doc

Is the k10temp module loaded? It's part of the standard ubuntu kernel.

  • /etc/modules only shows ip, rtc and it87 (last one added by lm-sensors) – BloodyIron May 22 '12 at 16:44
  • I added this to my modules list, rebooted, and I seem to have fan and CPU temp sensors now. Although I have 3 sensors now, I am not sure which one is CPU? – BloodyIron May 22 '12 at 18:18
  • Well on my i5... ls /sys/bus/platform/drivers/coretemp/coretemp.0 driver modalias power temp2_crit temp2_input temp2_max temp4_crit_alarm temp4_label uevent hwmon name subsystem temp2_crit_alarm temp2_label temp4_crit temp4_input temp4_max So it looks like it uses the hwmon interface. The hardware sensors applet works for me, just had to enter the prefs and enable the specific sensors. There's just so many of them. BTW it helps to accept answers that work to encourage other contributors. Thanks. – ppetraki May 23 '12 at 4:24

Please read this: PSensors don't detect all sensors

Another webpage, more detailed: http://www.cyberciti.biz/faq/howto-linux-get-sensors-information/

The steps you should follow are:

  1. install lm-sensors and psensor
  2. run sudo sensors-detect
  3. run psensor, then in the menus:
    • in /preferences/startup, click the launch at startup.
    • in /sensor-preferences, edit the labels to match your system. you cannot delete a sensor, but you can choose not to display it.
