Basically I have a Zalman ZM-MFC1 fan controller (which I like a lot, and would recommend), and I want to hook a fan or two up to the bare wire plugs (like a car audio system). Thing is, I would like to hook up a pci fan to the switch, and the pci only uses molex. Any ideas about how to go about doing this?

What color wires are in the molex connector? If they are just red, black and yellow you could just cut the plug off. Make sure the fan does not exceed the power limits of the controller.

Hmmm, I can't really get a clear view at the plug itself (I did a pretty intense job of cable management and I can't get to the plug), but it seems that only a red and black come out of the fan. I didn't remember that as being the case, I hadn't looked at this in a while. Then, next question. I'll take off the molex head, but I'll need some extra cable length. . .I'm ok just cutting out some cable from random parts I have lying around correct? I would assume it would be the same gauge, and I'll keep it the same color for convenience.

Edit: Here's the connector, courtesy of newegg:

Also, seems like it's a 12v fan, that'll do fine with my 12/5/off switch.

Should be ok. Be sure to use good quality connectors to join the wires. If you are soldering them use heat shrink tubing or 3M brand electrical tape. Other brands stiffen with age and loose their stickiness (7+ years in the car audio industry). Red is + and black is -.

The molex connector has two black wires which are both - negative, the yellow wire is +12VDC, the red wire is +5VDC. You want the +12V and one of the negative black wires. I would just cut the yellow and black wire from the molex connector and leave the other two connected to the connector with tape or heat shrink over the cut wire. You can use solder or crimp connectors to splice you wires, black to black, yellow to red. Use a similar gauge wire if you are going to extend the length.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
