4.3 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.
Side Fan — the side fan opening enhances graphics card
cooling. Just snap a fan into the bracket on the side panel so
that it blows air into the case.
Middle Fan — the middle fan is designed to cool the
CPU,graphics card or 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
into. This design is especially useful in cooling dual graphics
card implementations.
1. To remove the 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.
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 mount.
5. Clip the assembly onto the back of an empty HDD cage.
6. Connect the fan to the power supply.
4.4 Washable Air Filters
Front Air Filters – there is a filter located behind the
faceplate of each HDD cage faceplate. Two front air filters
come with the case by default.
To clean the filters:
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 if you have left about 2 inches
of slack in the cables.
3. Lift the tab upwards to remove the filter.
Side Air Filter – there is a filter located in the side fan bracket. It is located on the inside of
the side panel, so you must open the side panel to access it. Remove the filter by sliding it
out of the bracket.
From time to time it will be necessary to wash the installed air filters. Not washing the air
filter will result in high system temperatures and possible stability problems. We recommend
checking the air filter at least once a month initially. The frequency will change depending on
environmental conditions and system usage. Users who run their systems 24/7 will have to
check their filters more often than those who don’t run their systems every day.
