right I went and got a cpu fan for a project and it has 3 wires coming out of it; red, black, and white. the red & black I understand...is the white 1 for fan speed? if so can I ignore it? just need the fan to run, don't need speed control.

The third wire tells the mobo how fast the cpu fan is spinning. Though it doesn't control the fan speed. A lot of mobos will set off an alarm if they sense the fan spinning too slow. Of course, if you're mobo doesn't have the alarm then it's one old mofo mobo.

well you see its like this, its not gonna be anywhere near a mobo, its gonna have a pvc armored carry case that on occasion gets kinda hot for a few small fractions of a sec...oh yeah the oxygen content drops to near zero during those times
