Port Access Covers
These cover openings in the chassis
when PCIe slots are unoccupied.
5 – Fan
The temperature-controlled fan
provides cooling for the installed
PCIe cards and the chassis’

It operates quietly when the card
is running cool, and automatically
speeds up in steps as the temperature
rises. Do not block the vent holes on
the front or back of the chassis to
prevent overheating.
