Question DDR5 slots

[sargan]

New motherboard (Gigabyte X670E Aorus Master)
There are the usual 4 RAM slots
I will be installing Corsair Vengeance 2 x 32GB modules .... assuming slot 1 is nearest to CPU, is there any restriction on which pairs I can use ?
Thinking it best to use slots 3 & 4 due to Cooler size.

Dual channel configuration is always a2/b2, second and forth slot from cpu. Cpu -> a1 a2 b1 b2 -> edge of board.

What cooler have you got and orientation? Can you raise fan if it is protruding over the second dimm slot?

Fan is fastened to heatsink with wire and can be raised, long as your case is wide enough to have it clear ram in the second slot and panel closed.
