Fan wiring

I have an Antec Super Lanboy case. It comes with two 120mm fans pre-installed. Each fan has 2 thin wires, one black and one red. The black wire feeds into one of the black wires on a standard 4-pin power connector. The red wire feeds into the yellow wire of a standard 4-pin power connector.
My mobo is a DFI LanParty UT nF4 Ultra-D. This mobo has 5 smallish 3-pin fan connectors. Obviously, the big standard power connectors coming from the case fans will not fit into the mobo fan connectors. What do I do?
 
Plug the fans into the PSU. Some fans have a separate yellow lead that plugs into the mobo that detects fan rpm.
 
I highly recommend not connecting case fans especially 120m/m fans to the motherboard fan headers.

Just connect them to one of the molex connectors off of the power supply.

Some fans draw mucho amps that your motherboard may or may not be able to power without risking damage to your motherboard.
 
OK. I am plugging my fans into the PSU. However, my PSU does not have fan specific ports. It does have a specific port labeled VGA/HDD. And a specific port for SATA. The other 4 ports are labeled Con1 and Con2 and Con1 and Con2. Can the fans plug into any of the ConX ports? There are a total of six ports on the PSU (counting the SATA and VGA/HDD ports and more counting the cables that plug directly into the mobo). And the cables supplied with the PSU have multiple (molex?) connectors. I just was not sure if all the ports output the same amount of power. My PSU is the SurePower 500W Smart Cable PS from Mad Dog.
I also seem to remember reading somewhere that some video cards require a direct connection to the PSU. I do not see any connectors on my XFX GeForce 6600GT. Am I missing it?
