I got a Gigabyte 1060 6GB Windforce OC and my temps in Witcher 3 (max settings) top out on 78C with 70% fan speed. Overclocked 130 on core and 250 on Memory. In game the speed reaches 1974mhz but usually around 1950-60. Outside temp is 28C ,ambient is a few less probably. Are these temps okay? Or should i need ot be worried?
