Note regarding using fan speed controllers with TriCool fans:
The minimum voltage to start the fan is 5V. We recommend our users set 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 4.5 V 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 25.4 mm
Rated Voltage:    DC 12V
Operating Voltage:  10.2V ~ 13.8V
The Bottom Air Intake
There are intake vents at the bottom of the case right under the HDD chamber.
Fresh cool air will flow through the vents through the hard drives, and then flow 
into the motherboard chamber and exhaust by the two 120mm TriCool fans.
Note: Do not place the NSK2480 on a soft surface or over anything that will block 
the bottom air vents.
The Upper Air Intake
There are vents on the top panel above the PCI expansion slots. Fresh air will flow 
through them into the motherboard chamber to cool the VGA card.
Note: Do not place anything on top of the NSK2480 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 
chamber to cool the power supply.
Note: Please leave at least 1” (2.5cm) between the left side of the case and
