Passively Cooling A Radeon RX 480 Polaris GPU

This past week the fan on my reference Radeon RX 480 graphics card surprisingly died. It's been a number of years since I last had a fan go out on a graphics card heatsink with much better reliability these days, especially with the reference graphics cards. When deciding what cooling solution to use for this RX 480 Polaris card, I decided to try a budget passively-cooled solution.
