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.
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 use it every day.
