RX480 with Sapphire ghz edition heat pipe cooler, mem heatsink and fans.. bolt on.. I havent tested it yet but guessing it'll work.. the tdp of the 7870 ghz edition is 175 so it shoudl be ok.. I would have rather had a vapor-x cooler to try but couldnt locate one..
My Temps are arround 75°C @ 61% (arround 1500 RPM) with 1420(1,21v)/2200. But theres no further OC. I can get Stable 1430 with 1,26v but the Step is too high. 1440 ist even at 1,3v not stable. I would need better Cooling or a better Card. But my Asic ist good with 79,4 %. I dont know whats the Problem.
The secondary VRM temperature (i.e TSEN2) is intended for monitoring Loop 2 VRM temperature. Loop 2 is unpopulated on RX 480 so the TSEN2 will be VAUX instead (a dual purpose pin, as stated by the datasheet). The protection limits for the VRM are 115°C (GPU throttling), 130°C (immediate shutdown).
