    Pch temperature improvement

    Hey,
    finally a motherboard that runs fine after having only problems on rve, the maximus viii extreme, perfect temps for vrm 30-40 degrees c, perfect cpu temp @ 20 in idle and 30-35 degrees c in stress of course after setting vcore to adaptive and even done some manual voltage settings and stock without core sync my cpu was staying at @ 1,3v an now 1.1-1.15.

    The only problem, the pch is pretty hot, boots at 40 degrees and after gaming i get 50-55 which is allot for such a cold pc with more airflow than a plane. So i want to know if anyone know if the pch uses thermal pad or thermal grease, and if it uses thermal pad what thickness and w/mk and if thermal pad is any space between radiator and chipset? because why use thermal pad even if it is low tdp, pads are for irregular surfaces. I wouldn't want to do the silly thing to make a third water loop to cool a @ 4w tdp chip. )

    Thanks!

    I know it is ok, but not by my standard, it's the hottest component in my pc, except the 950 pro ssd. )
    I found finally a review saying it uses thermal pad and thermal compound too at the same time, if that's real that's noobish, i shall use only thermal compound if there is no gap between radiator and chip and if it is a gap will use a 17w/mk thermal pad to be sure all thermal gets to the radiator so i can see normal temps by my standards.

    Because my aim and question is what it uses and what can i use so i can reduce temps, as about safeness would be safe even at 60 degrees, doesn't mean i want a cpu at 20 degrees and 40-50 pch or even 60.

    Now my aim is to find if it has a gap between heatsink and chipset, if not, best use is of compund for this use, though i understand using a pad as it lasts longer without loosing thermal conductivity but it is poorer at it than compound.

    Thanks

    wow high ) yep know its fine still won't accept component hotter than 40 degrees il put phase changer if needed )
    leaving my joke aside, even the x99 stood at 30-35 degrees and this is so hot and allot lower tdp, need to take it lower, soon wil test if it has a gap between heatsink and chip and if not kryonaut to the rescue )
    Maybe by then nvidia will think of launching pascal finally.

    sorry to bring this old post alive again... but i thought I would like to play with PCH voltages in the BIOS to see if it would help lower the temperature without making the system unstable.
    So I changed the PCH Voltage to 0.8750 from 1.1100v and it seems that PCH temperature won't change. i still get PCH temperature around 60-70c when gaming even with case open .

    it seems so hard to lower the PCH temperature even voltage lower

    EDIT:
    I lowered the Voltage PCH even more to 0.8000v and still same temps. (IDLE TEMPS)

    That's weird. That does suggest that there is a thermal pad and thermal grease being used... you're saying it doesn't move at all, right?

    yes, on idle it will never go below 50-60 even if i lower the voltages on the pch. is it because the gpu card generating heat around that area. i dont know.

    I even got to 70 degrees in this summer, it is very very sensible to temperature around it. The only "fix", after changing even the thermal(as the stock was not high performance one as it has low tdp), pad is simple. I remove my m2 ssd 950 pro which had really high temps and finally that titan x have arrived finally i can use my second loop and watercool my gpu's as my ex gpu's were 2 strix 970 with stock cooling and they were the harmful bunch heating it, now i have between 38 and 41 degrees no matter what, so trying to isolate it from external heat is the only solution sadly, poor design but heh, there'es always a next version.

    Hi sucka

    The pch temp on my maximus viii formula shows 46c idling at the desktop.
