The Optional Fans; The Washable Air Filters; The Side Fan; The Middle Fan - Antec Twelve Hundred User Manual

The Optional Fans

There are two optional 120mm fan mounts—the side fan (on the left side panel)
and the middle fan (at the rear end of the HDD cage). We recommend using Antec
120mm TriCool™ fans and setting the speed to Low. These two fans should be
installed so that the air is blowing into the case.
The Side Fan — the side fan opening is there to enhance graphics card cooling.
Just snap a fan into the bracket on the side panel so that it blows air into the case.
The Middle Fan — the middle fan is designed to cool the CPU, graphics card or the
power supply, depending on which drive bays you install the HDD cage into. You
can use the middle fan on any drive cage you do NOT install hard drives in. This
design is especially useful in cooling dual graphics card implementations.
1. To remove the black middle fan mount, press in on the clips that secure the
bay to its cage.
2. Place a 120mm fan inside the mount and press it into place
so that the holes in the fan are secured to the mount.
5. Clip the assembly onto the back of an empty HDD cage.
6. Connect the fan to the power supply.

The Washable Air Filters

Front Air Filters – There is a filter located behind the faceplate of each HDD cage
faceplates. There is a total of three front air filters that come with the case
by default.
To clean the filter:
1. Remove the cage thumbscrews fastening the HDD cage to the 5.25" drive
bays and set them aside.
2. Slide the HDD cage forward about 1 or 2 inches. You will see the air filter
behind the faceplate.
Note: There should be no need to disconnect the power or data connections
from the HDD or the fan in order to remove the filters for cleaning. Just
make sure that you have left about 2 inches of slack in the cables.
3. Lift the tab upwards to remove the filter.
3. Use the long screws provided to
secure the fan to the mount. Do
not overtighten.
4. Run the power (and control switch if using a
TriCool™ fan) through the cable guide that runs
along the side of the fan mount.
