    The undervolt should be the first action for reducing the CPU temperature because it actually reduces the heat that it is produced inside the CPU. Then the FAN power is a second solution along with a good repaste.

    I tried to undervolt but haven't noticed any lower temperatures under pressure - also my computer started to BSOD so i returned to default. I havve 4860 and tried -75MHz on both cores and cache.

    Boom_austin which processor you have and how much undervolting you did? Please share!

    In my experience the undervolt can help reduce heat noticeably, but reducing the core multiplier for 3/4 active cores by 1x or 2x is going to have a more profound effect on heat reduction under heavy load with 100% cores active.

    rmu i didnt just underolt i also underclocked while 3 or 4 cores are being used. my undervolt was 90 on core 100 on cache. i beieve. i also lowered the multiplier by 1 on both during 3 cores and 4 cores. this jurastically lowered my temps like 6 or 7c and no more thermal throttling

    i have the g751jy with the 4710qm and a gtx 980m. if anyone else has noticed the gpu and cpu seem to be sharing either a heat pipe or a whole heat sink pad. either way to see your true temps of cpu and gpu run a dual stress test. that will yield you your highest temps

    Boom_austin, the G751JY (at least) shares heatpipes between the CPU/GPU:

    Boom_austin, that is an image uploaded to a notebookreview.com forum thread on the g751, they pulled theirs apart, not me

    Here is the giant thread, but I don't have the specific post number for that article:

    Here is the other image they posted of their G751JY internals:

    Hello everyone.I'm not sure if this question should be in this thread but can you tell me what should be the recommended temperatures for the CPU and the GPU for gaming in G751?For what temperatures we should strive and yearn

    78 degrees seems to be a good place to be for me.

    Guys, I have some news for you! And no, ASUS tech support didn't gave me any solution to my CPU fan rpm request. They keep telling me to update my drivers or go to the service for a repaste. Though, due to one user, Wishmaker, I have spent some time today and finally made up a fan profile for the G751 using NotebookFanControler . You can see more details over here: https://rog.asus.com/forum/showthrea...l=1#post467982 .
    I hope it will work for you too. If not, just give me the feedback to see where I'm going wrong.
