The FAN1, FAN2 and FAN3 cooling fan connectors provide a 12V current to the cooling

fans. The connector has a "rotation" pin to get rotation signals from the fan and notify the

system so the system BIOS can recognize the fan speed. Please note that only certain

fans can issue the rotation signals.
