The XFX RS doesn't have much better cooling than the reference blower style design. Small heatsink with relatively high temps, can't be overclocked with stock voltage but if you undervolt the graphics card you'll remain around 75 degrees under load. If you don't undervolt you'll reach 83 degrees without overclocking.
CTurbo already mentioned it, but for the RX 480 the MSI Gaming is quite solid. Cheaper too.
