Antec NSK 1480 Power Supply User Manual


 
5
These fans have a three-speed switch that lets you choose between quiet,
performance, or maximum cooling. (See specifications below.) 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 fans is Low. We recommend this speed to maximize
quiet computing.
Note regarding using fan speed controllers with TriCool fans:
The minimum voltage to start the fan is 5V. We recommend setting the fan speed
to High if the fan will be connected to a fan control device or to the Fan-Only
connector found on some Antec 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: 80 x 80 x 25.4mm
Rated Voltage: 12V
Operating Voltage: 10.2V ~ 13.8V
The Upper Air Intake
There are vents on the top panel above the PCI expansion slots and CPU area.
Fresh air will flow through them into the motherboard chamber to cool the VGA
card and the CPU.
Note: Do not place anything on top of the NSK1480 that will block the top air vents
The Rear Air Intake
There are vents right above the rear I/O panel and on the PCI expansion slot covers to
bring in fresh air to help cool the CPU and VGA card.
CPU Air Guide
The CPU Air Guide and rear air intake work together to provide fresh air to the
CPU cooler to enhance the CPU cooling. The CPU Air Guide consists of several
sections that can be adjusted to best suit each individual motherboard CPU
position.
The Power Supply Air Intake
There are vents on the left side of the case to bring fresh air into the power supply.
Note: Please leave at least 1” (2.5cm) between the left side of the case and
anything that could block airflow to the power supply. This is required so that the
power supply will have sufficient cooling.
