Antec fans are designed to plug into the PSU molex connectors. I know. I have three Antec 900's.
If you look at your fan connectors, one side is a male molex, the other side female. I plugged the top and rear fans together and fed them from one PSU molex connector. Did the same with the two front fans.
Two of my systems are highly overclocked quads. With all of the fans set to Low, my load temps are below 70 C.
