Toying with the idea of switching out the RX-480 reference non-heat-pipe cooler for a custom Sapphire HD5870 heat-pipe cooler. The HD5870 runs at 230W max-measured; so, its heat pipe cooler could be fine for RX-480 (which is set up for 150W TDP).

In looking at "tear down" photos of the RX-480, the cooling attach points and dimensions (relative to cooling) look standard -- just like the HD5970 -- but, when I get the RX-480 (now Friday), we'll see.

I'm taking the HD5870 out of service anyway -- so, I may try the cooler. Its "no extra cost" to me.

Just a thought that others may find useful for a reference RX-480 (use a cooler from an older card) -- if it works for me.
