Note: The minimum voltage to start a typical TwoCool™ fan is 5V. We recommend that you set the
fan speed to High if you choose to connect the fan(s) 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, which may start as low as 4.5V to 5V. Connecting a TwoCool™
fan set on Low to a fan-control device may result in the fan not being able to start because
the already lowered voltage from the fan control device will be further reduced by the
TwoCool™ circuitry below 5V.

There are total of three optional 120mm fan mounts—one side intake fan (on the left side panel) and
two front intake fans (at the front of the HDD cage). We recommend using Antec 120mm speed control
fans and setting the speed to Low. These fans must be installed so that the air is blowing into the case.
Side Fan – The side fan enhances graphic cards cooling. The fan should be installed so air is blowing into
the case.
Front Fans – You can install two 120mm fans to the fan cages in
front of the hard drive bays. To install the front fans:
1.
Remove the front bezel as described in section 2.1.
2.
Depress the two tabs on the left side of the black fan
holder and swing it outward. The holder will easily pull
free of the chassis.
3.
Secure your 120mm fan(s) to the fan holder with the
provided screws. The fan should be installed so that air is
blowing into the case.
4.
Reattach the fan holder to the case by inserting the right
side into the corresponding slots on the front of the case,
then rotating the holder back into position until it clicks
into place.
Note: In order to build a quieter system, we recommend NOT installing the optional fans unless it is
necessary for cooling. If you choose to install them we recommend using Antec 120mm
TriCool™ fans and setting the speed to Low.
