Got a new cooler for my Ryzen 1700. This is a size comparison between old stock cooler and the new beast Noctua NH-D15 SE-AM4. Installation was a breeze on Crosshair VI Hero even with high profile Trident Z RAM installed (love the secondary fan offset possibility). Just make sure case clearance is enough. I have Phanteks Enthoo Luxe. Stress testing temps went down 25+°C.
