Danger Den Cpu waterblock plumb which way?

[Greebo]

I just got a 2nd hand Danger Den cpu waterblock, the one with a connector in the middle and the other on the edge.

Sorry I haven;t got pictures.

Can somebody please tell me if the middle connector should be the inlet or the outlet?

the inlet goes to the middle if same block as mine.

water should go straight onto the fins
