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

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?
