    Asus Zenith II TR40 : Fan Expanion Card detected in Windows but not in BIOS.

    I have both Zenith X399 Alpha and TRX40.
    In both cases I use expansion fan card.

    In case of X399 Fan card is detected properly in bios and OS, but in case of TRX40 it's only detected under OS..

    I tried different bioses... reset the bios.. pull the battery etc.. nothing retrigger expansion card to be detected?

    I have Zenith II and the fan extension is not available in the BIOS. I am not sure that it actually should be as it's still an addon card.

    What bothers me most is that under AI Suite 3 the minimum fan speed is 60% for the extension card fans.

    injurer.. i think it's a bios bug.. I had expansion card available under bios in ZAlpha X399 board!
    In fact i had all my fans connected to it and I did all FAN speed assignments there.

    It's not available in bios now in TRX40, but it shows up in OS!.

    Hello,

    @ASUS, same request here! Please add extension card II support in EUFI on Zenith II series

    It would be also good to fix spin up/down time settings that don't have any effect regardless if it's set in EUFI or FanXpert
