I wanted to connect CM Storm Force 200 to my HAF 912 and my Motherboard is Asus P8Z68.
The fan has a molex connector for power and 2 pin connector. I know that molex=power.
currently I have connected only molex which is running the fan at full speed and without LED.
But there are 3 pin coonectors on my motherboard while the fan has 2 pin connector.
The motherboard pin details as as follows
1st pin Rotation, 2nd pin +12v, 3rd pin Grnd.
Now please help me to connect this fan to control its power(rpm).

I have already done that but one pin from motherboard connector will be left empty. My question is to leave which pin out.
I can understand that one of the connector has to be ground. I am confused between power and rotation connector. See the attached image for my mobo pins.
