I'm building a P5Q Deluxe system now with the TRUE Black heatsink.. Noticed that if I orientate the heatsink such that the fan attached on the heatsink blows towards the rear exhaust, the edge of the heatsink comes in contact with the northbridge heatsink.

Wonder if I should jsut go ahead, or change the orientation such that the fan on the heatsink blows towards the top of the case? Or is there something wrong with my mounting?
