The fans have a 3 prong connector and on my motherboard (asus p6t deluxe v2) is a 4 prong. Or do I have it reversed but either way. How can I make this work? Do I plug the fans into the chassis connector which match? Will the mobo adjust the voltage to speed up the fans when the cpu gets hot? Thanks

What I meant was that on my motherboard the cpu fan connector is 4 prong. On the 2 fans that come with the noctua cpu cooler are 3 prongs. From my understanding, if the cpu gets too hot, the voltage is turned up to compensate.
Now on my motherboard, the cpu cooler fans fit into the chassis fan connectors (NOT the cpu fan connector). If anyone can help it would be appreciated. I'm a little lost here.
p.s Anyone with experience with these fans? Which direction should I be facing them. I have them both facing the same direction, i'm just not sure if it's sucking in air or blowing air in the right direction. (Still waiting for power supply, just wanted to set everything up before i plugged it in.)
The 3 pin connectors fit quite well on the 4 prong MB connection. You do lose fan speed control, but I just run them on 'high'. They are pretty quiet on those settings, almost silent. They normally come with resistors to make them run slower, those hit the rubbish bin 2nd day I fooled around.
As to direction, they DO have wee arrows on them. Also, the wireing of the fan 'points' in the direction of fan flow, and the fan label is on the output side of the fan. As to direction of flow, that will be a matter of your case setup. Personally, I have both fans facing my rear exhaust fan, no controller, and my cooler is quite quiet.
Using a 3-pin on a 4-pin connector doesn't even lose you the fan speed control - it only loses the PWM (Pulse Width Modulation) control option, so it only loses some precision (about 5%). Voltage regulation is still there, so no worries...
