There is a 120 x 25 mm TwoCool™ fan preinstalled at the rear of the case. The fan is installed so the air will be
blown out of the case. This fan comes with a two-speed switch that let you choose the speed best suited to your
need. The default fan speed setting is Low.

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.
