I have same issue using just Nvidia 3070 with 7950x build. Do u have any fix? Thinking to return it. In my old pc I have Corsair AX1500 running 2x 3090. I always here the gpu fan. I never had a issue with PSU fan.
I bought this PSU so I can use when I get my 4090. but in my new build with TT GF3 1650 even with 3070 is going crazy.
