    I have an Asus P8H61MX_USB3 And i am wondering if somebody can help me before i post a Mod request.

    It only has 1 CPU fan and 1 3 Pin motherboard header, Downside is the 3 pin is stuck at 60% contantly, and I would love to know if it is possible to modify the bios Limits on Chassis Fan?

    As an Example :
    Chassis Fan Upper Limit 100% to 50%
    Chassis Fan Lower Limit from 60% to say 20/40%

    Also AHCI isn't enabled by default and can sometimes revert back to IDE > AHCI randomly.
    Is it possible to mod the BIOS to have AHCI enabled default and not IDE?

    Replace the cmos battery (CR-2032) and check if the settings now keep.
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    That's an Aptio4 bios. You could use AMIBCP v4.55 to make mods. Have a search in the bios tools section. Not sure about flashing modded files on Asus...

    Replaced it with 2 brand new Duracell. Also replaced 2 caps.

    It holds settings until you unplug the PSU long enough for the caps to discharge.
