    Well seeing as so many of you are complaining about the fans, i will share my solution with you. This solution is not proven by any means but works for me.

    1. start msi afterburner
    2. play your game of choice
    3. exit the game and wait 5-10 secs for gpu to cool down
    4. in msi afterburner hit the "K" tab on the left to start Kombustor.
    5. After 1-2 seconds the fans should go silent, when they do close Kombustor

    this method works perfectly for me, if it doesnt try to close afterburner and open it again and repeat step 4.

    I do not know if this method damages your GPU, so im not responsible for any damage you cause by trying this.

    Note: my afterbuner temp. graph is well under 50, so i think im safe.

    This actually seems consistent with my thoughts on the fan problem: when Optimus/Enduro switches to the integrated GPU, the dedicated one probably is completely "ignored", and leaves its fan exactly as it is at that moment.
    I'd say it's a bad BIOS coding, maybe.

    I think the fan keeps running is becuase you have GPU monitoring program on, the GPU will rotate between default clock and idle clock when the dGPU is being monitored, you have to make sure all GPU monitoring programs are off if you don't want to use the dGPU. And slight usage (monitoring too) will prevent the dGPU from shutting down. Also the GPU temp in ThrottleStop will prevent the dGPU from shutting down too.

    yes,kombustor can turn off the fan at idle if temp is below 49C

    Try open up CCC when all monitoring program are off, when I open up nvidia control panel on the GTX675M/GTX680M the fan turns off instantly when temp is below 45C.

    This also happens with HM models. It would have been good if the EM had been updated with better fan control.

    Does double-tapping Fn + 1 do the same thing as the kombustor trick? (if Fn + 1 is enabled on your PC)

    The Fn+1 Combo used twice does turn off the fan for me if temp is below 50-ish....It will come back on and stay that way though if temps exceed 50 again. Kind of annoying, but a small price to pay for this machine.

    Interesting... so it seems there might be a way to kill the fans via software...

    Fn+1 works for me. Both fans shut off and neither turns on again until the temp goes above 50C for either CPU or GPU. The GPU never turns on until I open a program listed as "high performance" that stresses it a bit. The CPU will turn back on its lowest setting while browsing, then it won't turn back off even when it hits its idle of 38C. It'd be nice if Clevo or Sager releases an update that does this automatically.

    Schenker Notebooks (mysn.de) published an BIOS Update for the P502 (P150EM) Notebook yesterday on their website.

    I'm not sure if I'm allowed to post the direct link of the bios upgrade files, so here is a description how you will get it:
    Goto: mySN.de | XMG XIRIOS XESIA | buy Schenker Notebooks => Support => Treiberdownload => XMG => XMG_P502 => BIOS => XMG_P502_MIT_BELEUCHTETER_TASTATUR. Files: P150EM_B05 and P150EM_EC05

    There is also a BIOS update for the P170EM (XMG P702) located at => XMG => XMG_P702 => P170EM_B06.zip and P17EMEC06.zip).
    Although the different BIOS version numbers between P150EM and P170EM, the changes are the same.
    The Schenker support stated in a german notebook forum that the BIOS Update fixes the issue that the gpu fans sometimes doesn't turn off when the gpu gets idle again.


    Important: If your laptop has an EC installed, you will first have to apply the EC05 (EC06 for P170EM) update and then the B05 (B06 for P170EM) update.
    To check if your laptop has an EC, just boot into your BIOS (press F2 when your notebook boots up) and search for an EC version number on the first BIOS page. If you don't find an EC version number, you most probably won't have an EC installed and you only need to apply the B05 update.

    To apply the BIOS update, you will have to boot into DOS mode. The easiest way is imho to create a bootable USB stick. Just google for "DOS USB Stick boot".

    Please consider that you update the BIOS at your own risk!
