Case Fans Question

I cannot figure out how to connect the 3 case fans that came with my Cooler Master Scout case. They are all pre-wired and the wires seem to route to the case header. I expected to connect these wires to the main board, but where are the connectors?
Any help appreciated.

Benchmark Scores real men do bench presses not bench marks.
you can simply attach the molex to the power supply female molexes.

if they are three pin, get 3 pin to molex converter.
or get a 3pin female and 3, 3pin males. connect the males to the female following the 3 pin layout,

connect all wires except the RPM wire.
connect the rpm wire for only one fan, or else the rpm will be mixed up LOL.
