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

check the fan control signal transistor.

Look out for sc70/sot363 components on the board

Hi i have rx470 4gb, its working but fans not spinning even if hot getting 75degree not spinning. İ tried bios and afterburner not worked. Did you solve problem? Which part is controlling that fans?

İ solved the problem i changed q1604 maked as "S1AH" and q203 marked as "S1AH"
