Echo Express SE II Inner Assembly
1 – PCIe Slots
These are x4 electrical (x8 mechanical)
PCIe 2.0 slots. They are also compatible
with PCIe 1.1 and 3.0 cards.
2 – Thunderbolt Interface Card
This is installed into its own slot and
may not be moved to another slot.
3 – Port Access Covers
These cover openings in the chassis
when PCIe slots are unoccupied.
4 – Temperature-Controlled Fan
This provides cooling for the installed
PCIe cards and the chassis’ supporting
Thunderbolt circuitry. It operates at
a whisper 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,
back, or bottom of the chassis to
prevent overheating.
