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 4000 II / NSK 4480 II / NSK 4480B II 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.
Specifications:
Size: 120 x 120 x 25.4mm
Rated Voltage: DC 12V
Operating Voltage: 10.2V ~13.8V
