4.2 Front/Rear TriCool™ Blue LED Fans
The Nine Hundred Two comes with two pre-installed 120mm x 25mm blue LED fans, one in front of each HDD cage to cool the hard drives. These fans are installed so the air will be blown into the case. Each fan comes with a speed control knob at the front of the faceplate. Turn the knob clockwise to increase the speed. The lowest speed is 1200 RPM while the highest speed is 2000 RPM. See the chart below to view the appropriate specifications.
There is one 120mm x 25mm TriCool™ blue LED fan pre-installed at the rear of the case. This fan is installed so the air will be blown out of the case. It has a three-speed switch that lets you choose between quiet, performance, or maximum cooling. This switch is located at the rear of the case. The default fan speed setting is Low.

Note: The minimum voltage to start a 120mm TriCool™ fan is 5V. We recommend that you set the fan speed switch 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 TriCool™ 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 TriCool™ circuitry below 5V.
