I've just received my computer - I have the HAF 922 case, i have opened up the side panel to reconnnect the fan that pcspecialist disconnected for the journey, but i'm having trouble finding where it goes, its one of two chunks of cables, one of them is plugged in and the other i have spare with no obvious space... there isnt a space on the fan itself or the the actual board itself, do i really need to connect this or will the fan work fine without? help? lol
