How do I connect this fans?

Solution
To be able to connect these, you will need to buy a product similar to this: http://www.amazon.com/Fan-4-Wire-Molex-Connector/dp/B000BSN5TE

Next, you need to cut off the red and black wires with side-cutters up against the molex connector. (The larger plug.)

Next, connect the wires from your fans to wires of the smaller four-pin header. Match red to red, black to black.

Finally, put electrical tape over / wire nut the connections and you are done.

I would advise just getting new fans though :)
