I left it unplugged, reset CMOS, set my overclocking using XMP and I got my boot problem with 00. Did the same overclocking but set to manual mode, and I could shut it down and boot it up with no problem.
And with it set to manual, I plugged the fan connector back and booted the PC up again and no problems.
Have to do more testing throughout the week but I honestly don't know what changed outside of XMP. It wasn't booting previously all on stock in bios with my old power cable, so don't know.
