OK here's how to do a 12v mod, but it's extremely loud. You will also lose the auto-adjusting functionality of the fans, where the voltage increases as the CPU temp does. That shouldn't be a problem though.

STEP ONE:

Take the RED and the BROWN wires shows below, and cut them off at the top of the plug, so you have the most wire left. Leave the BLACK and BLUE wires, as they're just grounds.

STEP TWO:

Twist, then solder the RED and BROWN wires together, then solder a third wire to that, about 5" long. Solder the OTHER end of the third wire to the pin shown below, either on the bottom of the motherboard, or onto the wire that does to the DVD drive.

And there ya go, both fans are now running at 12v. If you only want 1 fan to run at 12v, cut only one of the wires, RED or BROWN, and leave the other one alone. If you want 1 or both of the fans to run at 7v, then cut the BLACK and BLUE wires, and solder them to a 5v source on one of the USB plugs.

It seems there's a lot of people looking for this tutorial, but havn't seen it cause it was way down at the bottom of the page. So here's a bump, even though it's for no good reason.

Is it possible to strip 2 wires and connect a 3rd fan? For instance leave the regular fans connected, and just slap a smaller fan in another place connected to the same wires? If so... What wires would I need to strip to power another fan?

You say it's very loud, is it louder than the Xbox 1 12volt fan mod? I'd assume not since there 90MM fans right, but I guess there is two of them beasts.

So can you solder a 3 pin connector there and hook up a fan to that?

And bucko, these are 60mm fans, not 90mm

OK here's a good warning. Do not connect anything extra to the stock fan connector! It will blow a very sensative component on the mobo, and render the fan plug useless. Only draw power from the 5v USB, the 12v DVD, or that extra fan source it that's what it is. Btw, I believe they're 80mm fans, not 60mm or 90mm. I kinda measured them roughly, and 60mm is way too small. But 90mm is too big.

I didn't connect anything to the stock fan connector. I have connected a red wire to the 12v DVD-Rom connector and grounded the black to the metal plating. I then connected to that 5 fan connectors. However, for some reason only 3 wired fans work. 2 wired fans will not run. I have a fan with leds I wish to put inside, but it has only two wires. Anyone know a way I can get it to run? Also is that front connector working anyone tried it? Which is positive and which is negative on it?
