Caporegime
I gave my Fury a bit of a test in UT2004, which is still one of my favourite games. With VSync on to keep it at 60fps, the fan didn't even turn on. It's a bit of any easy test (GPU-Z reported an average of 1% GPU load), but it's still pretty cool to be able to run a high-end GPU fanless while gaming at all.
I played Half Life 1 on a R9 285 a while back it didn't even get out of 2D mode with a silly number of FPS. God the game look terrible though, even at 4k.
