For some reason after switching from 3.20 to 5.10 bios, when I have CPU_OPT fan set to DC mode, if I start the PC from powerless state (PSU off), the mobo will shutdown before POST screen and then boot itself normally.
That doesn't happen with Chassis Fan 3, which also has manual PWM/DC mode switch. |

looks like you flashed the bios wrong to start with.
* If the current BIOS version is older than P3.30, please update BIOS to P3.30 (Bridge BIOS) before updating this version. Not sure its makes any difference or if it will fix your issue if flashed correctly. |

Of course I flashed the P3.30 BIOS first, I just didn't mention it because it seemed like an obvious routine.

If I was up to updating directly to 5.10 I wouldn't even be able to choose it, it won't show up in the list until you update to 3.30.
