Alpha Omega Fan Molex to 3-Pin (4-Pin to 3-Pin Mb) FA-4-3
Use this adapter to power a fan with a 4-pin Molex connector from a motherboard that uses a 3-pin power-out connector. You can attach the fan to either the male or female 4-pin Molex connectors. Note: Don't attach either Molex connector to a power supply line if you're connecting the 3-pin to a motherboard, or shorting will happen.
