Hello, recently I bought a used 2070 Super XC Ultra and I bought a cooler for it(NVIDIA 2000 Series Coolers). I checked everything including the fan header for bent pins(None there) and everything looked fine on the hardware side of things. Then when I go to test it I get display and everything is working, but the fans do not spin. I tried through software to start them and nothing. Then I tried to see if they were dead by installing the accelero cooler and the fans do not work on that one either.
Well the heatsink on the gpu and some 140mm fans that I placed a little bit below the gpu to substitute the gpu fans kept it from doing either of those things, but still the point remains that the fans did not spin on the original gpu cooler.
