Laing D5 missing speedswitch

[grandpatzer]

So I recently bought watercooling parts and have recieved and inspected most of it, not tested however.

However it seems the D5 pump is missing the red circle speed switch on top of pump, instead there is a hole and in the hole there is a white square with what looks like a red pointer.

so my hope is that the switch has with time had to been removed and that the speed is adjustable with a long thin screwdriver?

Theres 2 versions of the D5, one with adjustable speed and a slightly cheaper one without.

It might still have the necessary parts on the board.
