Antec NSK 4480B The Front 80mm Fan, Learn more about 80 PLUS, Specifications, Speed, Input

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.

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
