I have an NZXT Phantom, a Gigabyte Z77X-UD3H mobo.
The fans on the case are 3 pin , and the ones on the motherboard are 4 pin (their both i think male, because there are no holes)
The ones on my power supply that look similar are 4 pin holes.
Do I conect them to my power supply, or mobo? Do I need a converter?
Fan controller wiring in your case
3 pin fans to the 3 pin connectors
4 pin HDD power from the psu to the 4 pin connector for the fan controller
