I found them! The molex power cords on the fans could disconnect and the 3 pin mobo connectors were there!

One last (I hope,) question. The fans also have a cord to the LED switch. The LED switch seems to have a 3-pin connector on them as well, but the cord is too short to reach the mobo. What is this for? Am I supposed to connect it to the mobo somehow? Or mount them on the case somehow so they can be switched on/off from the outside?

Would this adapter look like the one in the pic from my post except with 3 pins instead of 6 on the mobo end?
It's either one or the other. If you want the ability to control the fan speeds, plug the 3pin connector into the mobo header. If you want your fan running at full blast all the time, then plug it into the power supply using the adaptor. You don't need both at the same time.

Its either

fan->molex adaptor->psu (fan is powered by this, but the speed cannot be controlled)

or fan-> motherboard header (the fan is powered by this and the speed can be controlled in bios)

is the led switch part of the case fans, or the cpu fan? or is it the front panel connector? a picture would be great

They're attached to the case fans, they look like this:



They're pretty tiny. See the pins on the bottom? The button on the top toggles the blue LED for the case fans. Each of the fans has one, and I have no clue what to do with them.

So I connected all the fans to power and I'm not sure if I did it right. Here's how I have it set up now:

Front intake fan: Chassis fan 2
Top exhaust fan: Chassis fan 1
Rear exhaust fan: Power fan
Side intake fan: PSU

Is that OK? Here's what the BIOS looks like:





Why is chassis fan 2 red?

Is this because with all the fans hooked up to the mobo that there is not enough power? Or is it just running at a low RPM because it's a large fan?

well, the switch to turn on/off the leds, dont even worry about it. thats all they do. just tuck the cables away or leave them there, unless you plan on turning the leds on and off a lot. For the pins on the bottom, not sure, probably just an extension of the sodering job, but don't worry about it.

And for the red bar, I'm not exactly sure because when I saw that screenshot I honestly had no idea that was the bios lol. because this is what mine looks like: http://www.xbitlabs.com/articles/mai...p35-ds4_7.html

I would expect the red bar to be a warning that the fan is running too slow, but see if you can mess with the settings and speed it up. if its at max speed, then just leave it and dont worry about it. usually the large case fans run at lower RPMs, and the bios sees it as a problem but its really not.

Thanks! Do fans hooked up to the PSU run at full speed all the time?

Thanks, but there is one more fan than motherboard header. Do I plug the last into the PSU, or is there an adapter or something that would let me attach it to the motherboard as well?
