REAR EXHAUST 120 MM TWOCOOL™ FANS

There is one 120 x 25 mm TwoCool™ blue LED fan preinstalled at the rear of the case. This fan is designed to pull hot air out of the case. Each fan comes with two-speed switch that let 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.

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.

OPTIONAL FANS

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