fanheaders

hello, i ordered all the parts for my pc a few days ago but the cooler (cooler master ml240l argb) that i ordered wasn't on pcpartpicker an d i wasnt really able verify compatibility with the mobo. the ml240l argb seems to only be compatible with these View: https://imgur.com/a/MxTpbFd...

so i accidentally plugged a floppy disk power connecter into my fan header because it’s connected to my case fans and it started smoking. the chip next to the fan header blew. is my motherboard dead do i need to get a new one? do you think the other components are dead too?

I didn’t realize how little fans I could attach to my motherboard. So, I just bought a fan splitter from rosewill but I need to know how many fans I could attach to one header. On the front of the fans it says DC12V 0.16A. Can I attach two fans to one fan header on this motherboard without any...
