So I have 10 Arctic P12 ARGB fans for my build. I have them daisy chained so that 3 of them are on my motherboard (Z790 Edge) sys_fan2 header, 3 on sys_fan6 header, and 3 in the cpu_fan header, and the last one by itself. I've noticed that sometimes the 3 fans on sys_fan6 have a long delay before they start spinning, while all other fans follow the normal spin at 100% speed on boot then settle into the BIOS fan curve. The headers on the mobo are rated a max of 1A on the system fan headers, and 2A on the cpu fan header. The P12s specs say that they're 0.11A each, so shouldn't the headers have a lot in reserve just running 3 fans max each? When I contacted MSI, support told me that sys_fan6 wasn't drawing enough power, so it's not starting as normal, and advised me to connect only one fan to each header, and that he highly advises against daisy chaining into headers.
I'm probably going to just get a fan hub just to make this easier since the cable management is a nightmare with this many fans, but can someone explain to me why the fans aren't getting enough power from one header? Am I missing something?
