I bought a second hand EVGA GTX 980 K|NGP|N Classified video card but it has same fan issue. The fans are always off but if a set control to manual on EVGA Precision nothing happen until PC switch off. After the PC restart fans works on constant rpm but automatic control doesn't work at all. I stressed GPU to 90 Celsius but still nothing, always off.
I didn't check BIOS yet but my plan to change back original factory BIOS.
I spent few hours but didn't find an original BIOS just overclocked ones.
If anyone has a saved factory BIOS please send it to me?
