Where do I plug in my heatsink fan (zalman)? help!

[whatistaters]

I am installing a Zalman cnps9700 LED heat sink with my i5 processor on an ASUS p7p55d-e LX motherboard. When I attach my cables to the fan knob, it says to attach them to CPU fan, which a 4 pronged input. However, the fan cable only has 3. Where do I plug it into? There is no assistance in the heatsink's manual.
