Antec NSK 4480B - Manual (Page 6)

Note: The minimum voltage to start the fan is 5V. We recommend that our users
to 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.

Operating Voltage: 10.2V ~ 13.8V
The Front 80mm Fan
An optional 80mm fan can be installed to pull air into the case at the bottom front
of the case. A mounting bracket is provided for this purpose.
1.
Squeeze the upper right and left sides of the fan cage together to release the
tabs. Once loose, you should be able to pull the cage back and out of the case.
2. Drop the fan into the cage and push it in until it clips in. No screws are needed.
The front fan should be installed so that the air is blowing into the case.
3. Reattach the cage/fan assembly to the case paying attention to the wires of
the fan. There are slots near each corner to put the wires through (any corner
will work, find the one that’s best for you).
4. If you’re using a 4-pin fan, connect a 4-pin large white connector from the
power supply. If you’re using a 3-pin fan, connect the 3-pin connector to a
motherboard fan header.

80 PLUS® is an innovative, electric utility-funded incentive program to integrate
more energy-efficient power supplies into desktop computers and servers. The
80 PLUS performance specifications require power supplies in computers and
servers to be 80% or greater energy efficient. This makes an 80 PLUS certified
power supply at least 33% more efficient than current power supplies.
80 PLUS certified power supplies:
• Achieve energy savings, up to $70 over the life of a desktop computer
• Reduce a room’s cooling load, increasing comfort and saving up to 30%
•
Increase computer system reliability and save on maintenance costs by a much
as 40%
• Minimize the need for noisy fans, creating a quieter environment
• Save on construction — saves hundreds of dollars in electrical system upgrades
