Look in your user manual for your motherboard, as all ports are labeled. From what I am seeing, the "9-pin thing" you are looking at is most likely an internal USB port. That is NOT a chassis fan port. Your motherboard has support for just 1 chassis fan plugging directly into the motherboard. You can give the other fan power using a 4-pin adapter (such as this for SATA connections or this for Molex connections).
