Rear TwoCool™ Fan – There is a 120 x 25mm Two‐Cool™ 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 Two‐Cool™ fan set on Medium or 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
