tech suppot Cpu fan error with AIO

[XxMclovinxx]

Hi so i built my first pc today and everything seems to work but i get a cou fan error message on boot.

 

I have a corsair elite lcd h150i AIO and a corsair darkhero x570 motherboard.

 

The motherboard only has 4-pin fan headers and my AIO has a 3-pin with only 1 wire in it. I matched the plug to the header correctly when I plugged it in and even tried plugging it into the AIO header instead of the cpu fan one aswell but i get the same results 

 

any help would me appreciate.

The fan is supposed to be in the gray fan header, the CPU_OPT header is what you currently have the AIO plugged into. The other option is to just disable that warning in the BIOS, that's usually one of the first things I change in the BIOS if the board I'm using has that enabled by default.

 

Also FYI, your memory is in the wrong slot so you'll likely have issues getting XMP to work.

That's expected, because it's only a single wire (which itself doesn't make sense, since you need two wires at least). There's no sensing wire, so the system thinks there's no fan.

The one wire that's pinned up is the sense wire. It's just there to give an RPM signal to the board, power will have to be given by a SATA or Molex connector, not the motherboard.

Ah, yes. Been so long since I've dealt with those I'd forgotten. Never cared for that style so never really used them. Thanks for the correction.
