I am a first time computer builder and working on my first build. I was able to boot up with the cpu and ram hooked up to the mobo outside of the case. I then installed the components inside the case and attempted to hook up the case fans. My case has 4 fans, and I plugged them all into one of the molex cable and then into the mobo. I was unable to boot up. I then unplugged the molex cable from the chassis fan header on the mobo, and the mobo booted just fine.
The peripheral cables and fan connections are 4 pin, and the chassis fan header on the mobo is 3 pin. My case has knobs and adjustments that I can control the fan speed from the outside of the case so I imagine that i will be able to regulate the speed manually. I'm guessing that a disadvantage to not connecting the cable to the mobo, is that I can't monitor their RPM's? Do I have to connect the end of the molex cable to the chassis fan connection on the mobo for the fans to function properly or can I just give them power and leave the end of the cable unplugged?
