I'm confused with the fan wiring. I know the fan power molex plugs snap in to the power supply cable, but the small connector on the end doesn't look like it fits in the SYS_FAN1 connector. I don't see any other 4 pin plugs on the mobo for fans, every other fan plug is 3 pins.
This is the end connector, I think it goes in the SYS_FAN1 slot.
These are the molex connectors the fans plug in to for power.
