    What are the real temperatures of you CPU under load?

    When my laptop was still in stock form I could easily push the CPU past 90 degrees celcius just by loading the CPU. Adding in some GPU load would cause the system to overheat.

    Now that it is modded, I generally load at about 60c for most programs that utilize both cores, but can still push it into 70c territory by using programs designed to stress the CPU to its full capabilities.

    Since most people consider their laptops to be capable of running at full load without overheating I suggest we put this to a test.

    For Intel Core2 Duo/merom/yonah/dothan systems "Intel Thermal Analysis Tool" will load the CPU to its full potential and also show temperatures quite reliably. It is advisable to also run "Core Temp" to show temperatures as TAT does have a few issues with some systems.

    For AMD X64 systems, "Core Temp" can show temperatures quite accurately while the program "S&M" provides CPU loading.

    Intel Thermal Analysis Tool: http://shintai.ambition.cz/files/tat.exe
    Core Temp: http://www.alcpu.com/CoreTemp/ (download verison 0.95)
    S&M: http://testvram.nm.ru/snm.htm (Download version 1.9.0b - http://testvram.nm.ru/snm.zip)


    Note, to configure S&M for temperature testing you need to do these steps fr maximum CPU loading:

    -In "0" and "1" tabs
    -- only have "(Heat only! ) *" options checkmarked.
    -In Settings tab
    -- set CPU test sliders to "Long" and "100%".
    -- Only "CPU (FPU)" Should be checked under tests.
    -- In the "1 and 2" column there will be two checks to the right of "power"



    For anyone who does test their CPU, I would suggest aborting any testing should you reach 85 degrees celcius or higher. For disclaimer, anyone who does test does so at their own risk..

    Thanks to anyone who participates, would be nice to find out which laptop models can really handle the CPU they've been paired with or if the CPU's just for show.

    Wow.. that's a pretty nifty tool!!
    The highest temp I got from 100% load on my cpu (e6600 overclocked to 2.8ghz) is 78C.

    bump.

    Would be nice to see GPU loaded temperatures as well so that we can see if your GPU's are capable of full performance or just for show.

    Please give an idea as to ambient temperatures as well if you can.

    Thanks.

    My CPU is pretty stable, been running it for 20mins
    CPU 0: 48C -/+ 1 C
    CPU 1: 50C -/+ 1 C
    I do have it undervolted 0.300V

    My Opteron 185 in my U709, maxes out at 58C, and thats a 125 watt processor.
    My T5300 in my Dell maxes out at 56C, its undervolted 0.3V, to 0.950, and it draws just over 26 watts at max power.

    The Quadro FX2500M in my U709, peaks at around 55C, but I dont game or anything.
    The ATI X1400 in my Dell E 1505, peaks at 115F, using I8KFANGUI.

    (I always have my fans forces to full in order to keep temps down.)
