I have been given a CORSAIR Hydro CW-9060010-WW H55 120 mm CPU Cooler. I have the water block installed in the middle of the three Fan slots I have right at the top of the case.. Sorry the Lighting strips are hindering the picture a little. The question is about the direction of the fan, Would it be best to have the arrow pointing upwards towards the fins of the water tank. Or The other way around to pull air through instead..
