Good Day I have a Sapphire RX 470 8GB mining 1x dvi port which works fine only shows 0.0C temperature in gpuZ and fan runs at 100%,. looks like thermal sensor is broken, I thought thermal sensor maybe located inside gpu chip itself so i welded a new chip on it but the same problem, does anyone knows anything how to solve this problem, A boardview or schematic..? beside 0C problem the card runs perfectly fine and temps are around 55C under full load when measuring with external thermocouple. I hope someone will help me out. Cheers |
