I have all sorts or temperature indicators, one for each core and two for the gpu. but one is just showing "temp1" is there a way to know what temp one is showing? temp1 selected

I'm using Indicator Applet Complete 0.4.12 to see the temperatures.

When I ran sensors-detect I noticed that there was a virtual device. and "temp1" has the same critical temperatures.

$ sudo find /sys -iname "*temp1*"
/sys/devices/virtual/hwmon/hwmon0/temp1_input
/sys/devices/virtual/hwmon/hwmon0/temp1_crit

Do you get something for sudo find /sys -iname "*temp1*" or sudo find /proc -iname "*temp1*"? –  htorque Jul 17 '11 at 20:13
    
sudo find /proc -iname "*temp1*" Gave nothing. –  Alvar Jul 17 '11 at 20:39
    
Run sudo sensors-detect, answer everything with 'y' and post the summary. (Maybe need to install lm-sensors first.) –  htorque Jul 17 '11 at 20:56
    
@htorque this is what i get as "success" or labeled "yes" when typing sensors-detect Module i2c-dev loaded successfully. Intel digital thermal sensor... Success! Probing for EDID EEPROM'... Driver coretemp': * Chip `Intel digital thermal sensor' (confidence: 9) –  Alvar Jul 17 '11 at 21:03
    
But I still don't know what they control –  Alvar Jul 17 '11 at 21:05

The labels come from the libsensors config file - /etc/sensors.conf - and are determined based on chipset. When you see temp1 etc. it means there is no label defined yet for that sensor on that chipset. This is probably because it your hardware is new, or your libsensors is old (unlikely with 11.04), or maybe different vendors use the sensor for different things, or other reasons.

I would suggest using the stress or other stress-testing command to put load on certain parts of your system in order to determine what the sensor is for, and then add your own label into sensors.conf, eg.:

chip "lm87-*"
    label temp1 "M/B Temp"

Replace the lm87-* with your chipset as seen in the output of running sensors from a shell.

nice answer!There may also be a sensors3.conf. –  Takkat Jul 18 '11 at 7:41
    
What if "temp1" is located at the motherboard, what should I stress then? –  Alvar Jul 18 '11 at 11:13
    
Good point @Alvar. I'm gonna have to go with process of elimination tho, although it's not a real solution. CPU stress tests would also load the northbridge, which should raise the motherboard temp enough to tell it apart from the case etc. Although if you had two M/B sensors, I cannot think of a surefire way to tell which one is which, without knowing more about the system. –  drgrog Jul 18 '11 at 13:33
    
it may be easier just to look up where temp1 is located, will try that now... –  Alvar Jul 18 '11 at 14:21

This is Where they are.

Please edit your question to provide details of how to access this screen in your screenshot. That way others will benefit from your answer. –  Stephen Myall Aug 17 '12 at 14:30

Check out this webupd8 article:

Currently you can install the PPA version of indicator-sensors by running the commands:

sudo add-apt-repository ppa:alexmurray/indicator-sensors
sudo apt-get update
sudo apt-get install indicator-sensors

(This integrates the updated information about the official PPA into the commands given in that article.)

The article provides some information about how to configure it after installing:

Once installed, launch Indicator-Sensors from Dash (it's called "Hardware Sensors Indicator"). Then you'll need to configure it: click the appindicator and select "Preferences", then expand the various temperature modules you see in the Preferences dialog and check the box next to the temperature / voltage / fan speed you want to displayed on the panel.
