Optional Fans | Antec Two Hundred instruction

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.

4.2OPTIONAL FANS

There are total of three optional 120mm fan mounts—one side intake fan (on the left side panel) and two front intake fans (at the front of the HDD cage). We recommend using Antec 120mm speed control fans and setting the speed to Low. These fans must be installed so that the air is blowing into the case.

Side Fan – The side fan enhances graphic cards cooling. The fan should be installed so air is blowing into the case.

Front Fans – You can install two 120mm fans to the fan cages in front of the hard drive bays. To install the front fans:

1.Remove the front bezel as described in section 2.1.

2.Depress the two tabs on the left side of the black fan holder and swing it outward. The holder will easily pull free of the chassis.

3.Secure your 120mm fan(s) to the fan holder with the provided screws. The fan should be installed so that air is blowing into the case.

4.Reattach the fan holder to the case by inserting the right side into the corresponding slots on the front of the case, then rotating the holder back into position until it clicks into place.

Note: In order to build a quieter system, we recommend NOT installing the optional fans unless it is necessary for cooling. If you choose to install them we recommend using Antec 120mm TriCool™ fans and setting the speed to Low.
