The Nitro+ RX 470 is indeed a charged up version of the RX 470 coming in at a  boosted TDP of 175w over the normal 120w of the RX 470 and the 150w TDP of the  RX 480.  It comes packing 3x 10mm heatpipes to remove the heat from the cut  down Polaris 10 core and is blown away by two Dual-X 95mm fans.  Sapphire  has also revamped their TriXX 3.0 software to now support the full RGB lighting  found on the Nitro+ RX 480 and their new ‘Fan Health Check’ that allows users to  check the status of the fans on the card.  Should one of the fans be  defective or in need of cleaning they can easily be removed for easy  cleaning/replacing thanks to the new Quick Connect Service.
