You can connect the fans to the power supply with the molex connectors. They are the large 4 pin connectors on one end and plug into the psu on the other. Each molex can handle 2 fans. I your fans don't have 3 pin(small) to 4 pin(large) molex adapters you will need to get some. You can connect one fan to the front of the molex from the psu and ond fan to the back of the same molex connector.
