Are you still using the same heatsink? Or are you looking at possibly going with a heatsink with fins going the other way?
Yes I'm using it still. The fin direction on the aluminium and the copper version is different, but I don't have the feeling that it matters a lot. I could probably tweak some things, but then again, it is inaudible and the temperatures are very reasonable, so I have everything I need anyway
For the people who are interested in this heatsink but don't want to make one themselves, I have recently launched pre sales for a case that can hold a low profile gpu. This particular heatsink is sold as accessory, but can also be purchased individualy: https://n3rdware.com/accessories/rtx-a2000-heatsink
