Psensor physical id 0

My system has a 2nd Generation Core i7 2670QM @2.2ghz with the Linux kernel 3.4. Psensor (I am using it to check my CPU/HDD temp) is showing Physical id 0 at 50 deg C.

It also shows:

Sensor Information

     Id:                          lmsensor coretemp-isa-0000 Physical id 0

I want to know what is Physical id 0? Does that mean it's showing the temperature of the installed RAM module or something else?

I would also like to know if the temperature is normal or overheated? Thanks in advance.


Solution 1:

Physical id 0 is referring to your CPU. The CPU TJmax is 100 degrees Celsius. So 50 degrees Celsius is normal. Also make sure that ambient temperature is good.

Solution 2:

To complete the above answer which is obviously correct, here is the full list of Psensor sensord ids and corresponding type of chips:

  • ‘lmsensor coretemp’: Intel CPU.
  • ‘lmsensor k10temp’,'lmsensor k8temp’,'lmsensor fam15h_power’: AMD CPU.
  • ‘nvidia’ or ‘lmsensor nouveau’: NVIDIA GPU.
  • ‘hdd’: hard disk drive.
  • ‘amd’: AMD GPU.
  • ‘lmsensor C B’: C is the name of the chip, B the name of the adapter.

Since Psensor 0.7.0.4, the chip name is available in the sensor information window:

Intel Chip

Some technical information about your CPU is available at: http://ark.intel.com/products/53469, maximal temperature is 100C (Tjunction), so 50C is fine.
