SenorJanko Posted April 19 Share Posted April 19 Hello, I am currently at work and was thinking about adding a 2nd hub to my system and adding more fans to it. PSU has enough power and a free USB2 header is also available but I am curious about the CPU fan connection which is occupied by the 1st hub in the system. How do I need to wire things for the 2nd hub to work? Its probably super easy and im just to dumb to think about it right now. Best regards Link to comment Share on other sites More sharing options...

That is not a power delivery connection. It’s a tachometer wire only, to satisfy the motherboard’s “CPU boot protection” feature. It won’t let you boot up unless something is connected to cpu fan. That wire reports a pump speed to the bios in order fulfill that obligation. All you’ll need is a usb 2 for communication and another 6 pin pci-e for power — and more CUE Link cables. 1 Link to comment Share on other sites More sharing options...

God damn the moment I read your answer I got it. I remembered a topic in this forum where some people had an issue with the CPU Fan Message even while they had the cable connected and there was the same answer... Thanks! 😄 Link to comment Share on other sites More sharing options...
