difference between core and real temp

Hi guys
i have been using both core and real temp to monitor my cpus temp however there seems to be about a 10 degree difference between the two programs core about 50 and temp about 40. which of these is the correct temp value?

  1. From my experience; I used
    RealTemp 2.6
    Core Temp
    And always RealTemp was giving 10 degrees less than others
    I was also worried which one to trust
    Then in a long topic I learned that Speedfan is the best if calibrated
    as explained in the sticky for Computonix
    And someone did exactly what was in my mind
    He calibrated Speedfan and compared the result with Real Temp
    and guess what ?
    Difference was 1 degree
    So, Real Temp is the best
  2. Realtemp is definitely the best, even better when calibrated. There is a thread at xtremesystems.org
  3. alright thanks guys
  4. how do I know what to set my tjunction value too in real temp?

    Q6600 b3= 95 or 100
  5. Heh... there isn't a best.

    Those programs won't detect the tjuction max, which they depend on. So the software programmer set it to what they believe it to be.

    CoreTemp THINKS the TJmax is 105 for certain CPU's... namely Q6600.
    RealTemp THINKS the TJmax is 95C for certain CPU's... again, Q6600.

    So there is no better program out there. Your best off going by the Tcase Sensor, since Intel doesn't publish the Tjunciton max, but does provide the thermal spec, which would be related to the Tcase max.

    If you have a Thermal Spec of 71C, then your Tcase temp, or bios temp, shouldn't exceed that temp or get near it.

    The same would go for SpeedFan program.

    You can adjust the Tjmax on RealTemp, CoreTemp. You can only offset the cores on SpeedFan. If you run the Hardware Monitor, you won't be able to adjust anything, so it will assume the Tjmax, just like the others, but no adjustment.
