I noticed that you said the package contents only come with 12 memory heatsinks, but in the guide I noticed you used 16, so I'm assuming you used a kit for the old GTX cards? Also, the guide didn't include instructions on how to install the backplate, something that I was really looking forward to reading. All-in-all I am convinced on getting this cooler and pairing it with the R9 290 (not X).
