I have installed psensor and see a list of temperatures, but listed as ”Temperature 1”, 2, 3 etc . I can only guess where the processor is: but who's who for sure?

The same question stands for Sensors Viewer.

I can also type

sensors

in Terminal but I get no more than that

enter image description here

acpi -t

gives

Thermal 0: ok, 65.0 degrees C

Thermal 1: ok, 37.9 degrees C

Thermal 2: ok, 56.0 degrees C

Thermal 3: active, 71.0 degrees C

Considering psensor, I know for a fact that:
- the temperature that varies most depending on the CPU use is Temp1 and it is one of the two highest
- the other high temperature is Temp4 and it goes to the ceiling when using youtube/flash
- Temp2 is very stable at a medium level of 50-60 degrees Celsius
- Temp3 is by far the lowest and most imobile

So, I guess Temp1 is the CPU temperature, and Temp4 is the GPU temperature.
Temp2 and 3 must be the motherboard and the hdd.

Does anybody know for sure?

From here:

Psensors makes use of lm-sensors and hddtemp to get the temperatures, so you need to install these two packages:
```
sudo apt-get install lm-sensors hddtemp
```

To get the hddtemp daemon to run on boot, use the following command:
```
sudo dpkg-reconfigure hddtemp
```

and select "Yes" when asked if hddtemp should run at boot. Select the defaults for the other questions.

Next, you need to set up lm-sensors by running the following command:
```
sudo sensors-detect
```

And answer "yes" to everything.

To avoid a system restart, run the following command to load the modules required by the sensors:

sudo service kmod start

(if no sensors show up in Pensor, try a system restart)

Install Psensor

The latest Psensor 1.0.2 is available in its official Unstable PPA for Ubuntu 14.04 only for now (it will be available in the stable PPA after the new packaging is accepted into Debian).

To add the Psensor Unstable PPA and install the latest Psensor in Ubuntu 14.04, use the following commands:

sudo add-apt-repository ppa:jfi/psensor-unstable

sudo apt-get update

sudo apt-get install psensor

What stands behind each name in the list can be seen by going to Sensor preferences, and look at the info for 'Chip'.
