I just wanted to know the details of this process. My case fan only has a 4-pin molex connector. Does that mean that if I use my motherboard settings to control fan speeds it will NOT control that fan (because it's not connected to the motherboard fan detectors?) If this is true, how do I connect it to the little 3 pin plugs on the motherboard? Second question: My secondary case fan comes with a 3 pin plug attached to it, and then it plugs into a 4pin molex adpater and into the power suppply. Can I just plug that little 3 pin plug into the motherboard or is that not what it's for? Thanks for the help, really apprecaite it!
