What has all this to do with my answer? I was writing about the heat sink you are planning to use.Huh wait, so after reading the full TS this is how I figured out that my fat 27 inch iMac Mid 2010 was one of the best supported models.

So I don't see why the RX480 wouldn't work?
You can - of course - do as you please, but do not complain here after burning the best bang for the buck on the current heat sink.
P.S.: You need no copper plate and I am sure it has never been mentioned to use one with the RX480. Just stick to the GPU table information and do not confuse rows or lines. We will not cross check …
