    CPU Overheats in linux

    i dont know why but when on windows, my laptop cpu goes to 75-80 but when i play it on linux besides the low fps, cpu temp. goes to 90-100 C. is it related to linux or dota linux release ?

    I'm more inclined to believe it's more linux under stress related than linux dota. Can you try running any other intensive app and check if it heats it up as much ?

    i think it is about linux :/ i have just tried amnesia the dark descent in both linux and windows. linux has worse performance and more heat.

    In my case dota 2 is the only game that makes my notebook overheating and then i got forced shut down(all fans are clear, never had a single reboot before)

    The problem is your notebook/laptop's fans that can't cool off your unit properly when the CPU/GPU is under heavy usage. Using a software that also uses 100% cpu and/or GPU on Windows will also overheat your unit.

    I use this script to decrease heat:

    CPU="cpu0 cpu1 cpu2 cpu3"
    MAXFREQ=1000000
    for a in $CPU; do
    echo $MAXFREQ > /sys/devices/system/cpu/$a/cpufreq/scaling_max_freq
    done;

    In linux, you need the cpu frequency scaling.
    Runs this in command shell :
    Code:
    modprobe cpufreq_ondemand
    echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

    What is your idle cpu at? You might also have some processes that are sucking up unnecessary amounts of cpu

    But he already stated that in Windows his CPU don't do that while playing Dota. Just try comparing TF2 in both Windows and Linux if the result is the same then it's cause of Linux. Linux runs my CPU more then windows as well. Especially if you got Ubuntu Pls don't tell they should not play on Laptop, ofc if they had Desktop people would play on that. Laptops always have problems with overheating.
