The Zirconium offers several ways to cool down the hardware inside. You start out with the pre-installed 120mm, Revoltec “Air Guard”
which is rated at 1200rpm. Optionally you install a second 120mm fan in the front. Your third option is to swap the air duct in the side panel with an 80mm fan, something which we don’t recommend doing.
To be able to reach the front fan holder you need to remove the HDD cage, which can be done by removing a couple of screws. Not quite plug and play but swapping out case fans is not a daily routine for most.
The RT-101 features a dust filter for the front fan in-take, to be able to access it you need to remove the front panel. This requires some force to be able to pull the plastic frame from the metal one.
Once removed you can access the dust filter easily:Installation
With the front panel removed we now also have access to the 5.25” bays to install an optical drive, two different rails can be snapped on the device, one set for installation in the normal bays, the other set is for the “hidden” bays which flip open.
While not necessary for a good fit of long 5.25” devices, you can screw the drive rail to the chassis, this will come in handy for half-length 5.25” products like fan controllers.
