1 – Fan
The temperature-controlled fan
provides cooling for the installed PCIe
cards and the chassis’ supporting
Thunderbolt circuitry. 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.
