    I have the same problem.

    The chipset temperature reaches 72°C in idle (~3300 RPM PCH-Fan).

    My Vega's right over the chipset cooler.

    In games the chipset reaches 75-77°C maximum.

    Hopefully you can control the PCH fan manually in the next BIOS.

    BIOS 0802 didn't fix the problem. It would be nice if the hidden menu would be displayed. It is already build in (see attachment).

    Maybe with the next version

    Hi, can you tell me where to find BIOS 0802? On the ASUS homepage I only see the old 0702. Thanks

    I just registered to report that with Asus Prime X570-Pro and a GTX 1080 Ti Strix installed on the first slot, my PCH reaches 80C while gaming because it sucks all the hot air from it. Also, my chipset fan maxes out at around 3600 rpm.
    With a room temperature of 28 degrees, my PCH idle temperature is about 68C.
    Are these normal temperatures?

    I'd say these are normal temperatures right now.

    Hopefully you can set the fan speed with a next BIOS.

    anyone tried running the gfx card in the second pcie slot and see effects on PCH temps? Is there much of a performance hit to run off the second slot?
