There are two 120 x 25mm TwoCool™ Red LED fans preinstalled at the rear of the case. These fans are
designed to pull hot air out of the case. Each fan comes with a two-speed switch that lets you choose the speed
best suited to your need. These switches are located at the rear of the case. The default fan speed setting is Low.

There is one optional 120mm fan mount on the left side panel. A fan can be placed here to enhance graphics
card cooling. We recommend using Antec 120mm TriCool™ fans and setting the speed to Low. This fan
brings cool air into the case.

Note: The rear TwoCool™ fans have a two-speed switch that lets you choose between quiet or
maximum cooling.
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.
