    Thumbs up Make CPU to work to max

    ///"Works in XP/ for vista also but must use some different options."////

    Some times it is good to do some tests on CPU overheating.
    For that you need to make it work to 100% for a while. (about 20+ min)

    Yes, you can use scripts in cmd.exe to do that work.

    script N1: one line script
    @for /L %i in (0,1,999999999999) do @echo %random% > nul

    scipts N2: nonstop scripts, untill you push Ctrl+C
    @for /L %%i in (0,1,999999) do @echo %random% > nul
    @goto ag

    script N3:
    @echo %random% > nul
    @goto ag

    you can always start few tasks(scripts) at the same time to make it work harder.

    @for /L %i in (0,1,20) do @start /REALTIME CPUscript.cmd

    to make it easy to stop it make prepare cmd window with this kommand line:
    @tskill cmd*
    just push enter when tied.
    // too far away outside of limit

    SiSoft's "Sandra" is a pretty good tool:

    There are some other tools at the bottom of the page

    Prime95 or orthos, there is quite a few.

    has SPECviewperf for benchmarking Windows and Linux OS's also. It should put your CPU to 100%.
    Computers do not have problems, they have users.
