Laptop gets overheat while playing games..about 95C

    You are great sir. You have solved my issue. intel gpu now shows maximum 78C(75C average) and nvidia gpu shows 71-72C at maximum. and all of this was measured in a non-AC room.

    HWinfo64 shows that it has reduced my clock speed from ~3.4GHZ to ~1.9GHZ. Laptop doesn't feel hot at all.

    -none of my power plans showed the processor state option.
    -yes i checked that "change settings that are currently unavailable" option but it doesn't show anything.

    I have a few additional questions...

    1- Is it okay to delete the cooler.pow(its on the desktop)
    2- I think I am getting better FPS in games. Is it possible?
    3(edited)- now as the issue is solved, can you tell me if this "overheating" issue was normal with my laptop, or is there something wrong with my laptop? should i still be worried about overheating?
    4- does the cooler.pow disables turbo boost?

    Edit- yes i can confirm (2). now i can play wwe 2k15 in very high settings. previously i was playing it with minimum settings.(well the game is not properly optimized)

    tested another game- assassins creed unity. same fps as before.

    Edit 2-

    i found the issue. it was not the cpu using higher clocks, but the gpu.

    i did so by comparing cooler.pow with my power plan. i found that ...in cooler.pow, the settings "intel graphics settings>intel graphics power plan> was set to

    plugged in: balanced
    on battery: balanced

    the same settings in the power plan i use(power4gear high performance) was set to..

    plugged in: maximum performance
    on battery: maximum performance

    so i set power4gear high performance's intel graphics settings to same as that of cooler.pow.

    then i ran games on both power plans. the cpu clock rate in cooler.pow was ~1.9GHz; while in power4gear high performance it was ~3.2GHz. both power plans showed maximum ~78C for both nvidia(~1100MHz) and Intel gpu(600 MHz).

    but when i changed "power4gear high performance" intel graphics plan to default(i.e. maximum performance for intel gpu), the intel gpu got 1200MHz and became 95C hot.

    I'm glad it worked.

    Your findings are correct.
    I get similar results with the same power plan but different machine.
    Cooler power plan reduces clocks of CPU and seems the Intel HD graphics is affected as well since its located on the CPU.
    I've set the rest of options to 'moderate' just to make sure.

    1- Is it okay to delete the cooler.pow(its on the desktop)
    Yes, the power plan has been imported from there so you can delete it without worries.


    2- I think I am getting better FPS in games. Is it possible?
    Not sure, but for games that rely mostly on GPU I believe so. Got a 'heat' theory, it depends on how less heat would act on the needed components. The Cooler power plan reduces CPU and since Intel HD Graphics is on the cpu, it reduces its temperature as well. Nvidia is not affected by the power plan directly since the power plan doesn't have GPU options (some moderate performance on the PCI express exists though). So less CPU/intel HD heat might give nVidia more breathing space since nVidia is discrete and only kicks in when needed (@ 3D) and it's important to know that CPU and GPU copper coolers join together at the copper/aluminum cooling grid near the fan: if CPU gets very hot, some dissipated heat will reach the GPU as well even if at that moment GPU isn't too hot; the other way around is also possible.


    3(edited)- now as the issue is solved, can you tell me if this "overheating" issue was normal with my laptop, or is there something wrong with my laptop? should i still be worried about overheating?
    I don't know if others with the same laptop experience the same issues but chances are pretty high. Ultrabooks or thin laptops always heat up fast, especially when running 'big' games, since the chassis is thin and then so are the inside coolers + nVidia 840M + i7 4710HQ is a recipe for heat ups; in this case keeping a cooler power plan for backup isn't a weird idea at all. My laptop gets hot as well, there is a metal part of the case that heats up faster than the plastic but the Cooler power plan runs most of the time the CPU runs high. One of my previous laptops literally got a dead GPU in about a year when temps reached above 90°C each time, we learn from mistakes...


    4- does the cooler.pow disables turbo boost?
    Yes, your CPU should get 3.5GHz for 100% power plan, in turbo and is rated at 2.4Ghz for max non turbo (read 99% in power plan)
    More info on your CPU: ARK | Intel® Coreā
    So (for 80% cpu power plan) you have 1.9Ghz on Cooler: not bad at all; that should be enough for an i7 in a thin laptop if the rest of the power is needed for the GPU.
    Don't let the laptop melt just yet.

    Cheers!

    I think I was able to find out why the min/max processor power state options were not available for me..
