4 Pin Molex Connector with 2 Pins?

[Spooky_GER]

Hello,
im building my first own pc today, and I have a question.
I got the Aero 800 pc case, which has 2 preinstalled fans. I have a fan on the back which has an normal 4 pin molexconnector and I have an red led fan on the front which has an 4 pin molexconnector, but there are only 2 pins in the connector itself.
Is this normal?

Btw sorry for my bad english. :S

Yes thats fine, just plug them into a normal molex connector from the power supply, the fans only need 1 ground (black wire) and the 12v line which is the yellow wire, they dont need the 5v (red) or other ground, so theres no need for them to be there.
