    Speedfan, CoreTemp and the built-in Toshiba PC Health Monitor all show similar temps, whereas Everest shows different, higher temps. Which one should I trust?

    Specs:
    Toshiba Satellite A505-S6989 Laptop
    2.1 C2D
    4GB ram
    nVidia 230m
    Win7 HP
    This is a new laptop, drivers, bios all up to date AFAIK
    If you need any more info let me know

    I am not sure if you can even measure 2*C difference considering they both reside within the same die.

    ie, just a few micrometer apart and you can measure a 2*C difference?

    Keep in mind, unless you programmed the app, those temps could be up to 10 seconds off, it doesn't matter how often the screen refreshes...

    If Everest polls say every 5 seconds, that could actually be the reading from 5 seconds before.

    Hope I explained it. BTW, I'd go with the consensus. If 3 are the same and 1 is off, then I'd suspect the 1 off before the other 3 to be closer in time to true.

    You know, I never questioned this either, but I'm sure that this is feasible. These apps have been floating around the net for a while since the introduction of dual core cpus. Now with tri and quad core, these apps have been updated to account for the extra cores as well.

    Since I don't deal on this scale on an everyday basis, it does seem like an unlikely scenario, but I'm sure at Intel and AMD, they implemented some kind of sensor on a nano scale to measure these differences, which let app writers utilize the info in their programs.

    I hear you. The numbers do skew a bit, but when I let the system go idle for say 10 minutes or so, Ill check the temp log file and over time Everest will be about 10C above the rest.

    SO I dug around and found out the I had to set the TJMax in Everest to 90*C since the default is auto (I'm assumng 100*C). After that Everest now reports the same temps as the others.
