This is a modded version of ROG Crosshair VIII Hero's UEFI to eliminate the unnecessary PCH fan noise with a better fan curve. This also unlocks the Q-FAN controls for PCH.
Download the C8H.CAP to a USB drive and update your BIOS. As with any BIOS update, all your BIOS settings will be reset to default.
