Slave modes aggressive fan profile is just too loud for me. I really don't care about anything above 1900-1950mhz because the in game performance increase is like 1FPS and I gain more from just adding 300-400 memory OC. For that reason I undervolt it to 1900 @ 0.931v to make the noise manageable. With that same undervolt my STRIX sits at 1200-1300RPM and is borderline inaudible.
I donated this card to my brother who is gonna sell off his 1070 as the STRIX is just better for my needs.
