Here with my MSI 980 first fan starts at 50°C and stops when temp falls below 40°
Seconds fan starts at about 60°
Asus Strix should be better choice... fan starts at 65° and stops at 53°
Tried to Flash Asus Strix 980 bios to a MSI 980 GTX...
Flashed ok, but when tried to install Driver -> crash with green screen
Reflashed MSI bios -> all ok
