These are often used to power other devices in your case, such as the LEDs on the case front that you can set for the cpu speed, fans, etc.. If I remember correctly they run 12v.

Two things come to mind.

1. CPU fan.
2. Hard Drive led (connected to the hard drive controller). Does your hard ddrive light ever come on to indicate the drive is being accessed?

Just some thoughts.

Out of curiosity, since you have had two people say essentially the exact same thing, why did you reject my answer?

If you don't mind, in the future, could you put a comment stating why when refusing an answer? thanks :)

Will do, good suggestion may avoid some unpleasantness.  I don't think that they should use the word rejected.  Doesn't mean that I don't like your answer or think that it's wrong I'm just not in the habit of taking the first thing that comes along.
