SLI on the chvfz, will lane four be 16x?

So I'm thinking for heat and stuff could I use the second card in the bottom pcie and still have both on 16x? Or will it run at 4x?

PCIe x16 slot number 4 (slot closest to the edge of the board) is x4 speed only. For SLI it is best to use slots 1 and 3. Both will run at x16 speed.

Yh I have one and three atm was just wondering for better airflow etc cos if you look at the gpu dimm menu in bios it says they are all 16x so wondered if it meant that two, any two slots would run 16x then add a third card to any then 8x etc
Does that make sense?

They are all physically x16 slots but the last slot is x4 electrically (4 PCIe lanes) only.
