To install a floppy or other external 3.5" device to the 5.25" to 3.5" Adapter:
1. Slide the Adapter out.
2. Place the drive to the adapter and fasten the drive with screws provided.
3. Find a 4-pin floppy power connector on the power supply and connect it to the
male 4-pin connector on the devices.
Cooling System
The TriCool™ fan:
The case includes one 120mm TriCool™ fan installed in the rear. 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 blowing
out of the case. Connect a large 4-pin connector from the power supply to the
male 4-pin connector on the fan.
Note: The minimum voltage to start the fan is 5V. We recommend that our 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.

The Front 92mm fans
You can install two 92mm fans to the fan cage in front of the internal 3.5"
drives. These fans must be installed so that the air is blowing into the case. We
recommend using Antec 92mm TriCool™ fans to balance quiet performance with
maximum cooling. See our web site for product information. Note: Please choose
your fan speed wisely. In most cases, a medium or even low speed setting will be
enough to supply adequate cooling.
