3.4 Rewiring Motherboard Header Connectors

There may come a time when you need to reconfigure the pin- out of a motherboard header connector. Examples could be for your USB header, audio input header, or some other front panel connector such as the Power Button connector.

Before performing any work, please refer to your motherboard manual or your motherboard manufacturer’s website to be sure of the pin-out needed for your connector. And we strongly recommend making a notated drawing before beginning work so that you can recover if your work is disturbed.

1.Determine which wires you need to remove in order to rewire your plug to match the USB pin-outs on your motherboard (refer to your motherboard manual). Working on one connector at a time, use a very small flathead screwdriver or similar tool to lift up on the black tab located beside the gold posts (squares). This will allow you to easily slide out the pins from the USB plug.

2.Working carefully so as not to damage the wires, connectors, or pins, slowly remove the pin from the connector. Repeat these steps for each wire you need to change.

3.Working carefully so as not to damage the wires, connectors or pins, slowly reinsert the pin into the correct slot of the connector then snap closed the black tab that was lifted in step 1. Repeat these steps for each wire you need to change.

Cooling System

4.1 Rear Exhaust TriCool™ Fan

The NSK 4482 / NSK 4482B comes with one 120mm TriCool™ fan pre-installed. This fan has a three-speed switch that lets you choose between quiet, performance, or maximum cooling. (See specifications below.) The fan is installed so that the air is exhausting. Connect a large 4-pin connector from the power supply to the male 4-pin connector on the fan.

Note: The default setting of the fan is Low. We recommend this speed for maximum quiet computing.

Note: The minimum voltage to start the fan is 5V. We recommend that users set the fan speed to High if you choose to connect the fan to a fan control device or to the Fan-Only connector found on some of Antec’s power supplies. A fan-control device regulates the fan speed by varying the voltage to it. The voltage may start as low as 4.5V to 5V. Connecting a TriCool™ set on Medium or Low to a fan-control device may result in the fan not being able to start. The already lowered voltage from the fan control device will be further reduced by the TriCool™ circuitry below 5V.
