Modified fan duct for Noctua NH-D15

thingiverse

I remixed this to have even more clearance so it can fit in my NZXT H510 case, which can fit coolers as tall as 165mm. Everything fits perfectly (with a few mm to spare!) with the side panel on. The RAM installed is Corsair Vengeance DDR3, which is about as tall of a ram module as you can get. My cooler is an NH-D15S with the fancy heatsink covers. I also modded the top of the duct to match the contours of the NF-A15 fan, but you'll need to round the corners off with a file for it to match perfectly.
