How do I get all my case fans to work at once? I just built my system with an Intel Desktop board D865GVHZ motherboard. When I plug in both case fans, only one will come on. I have tried plugging it into each of the available plug ins for fans. My case has an lcd window in front to monitor fans and temp, but shows only the one fan on. I have gotten two high temp alarms now. Each time, it cools down from 57 to 47c after alarm, but I really would like to avoid high temp with fans working. How do i get them both to work??
