Lag :
is the idle temperature for the MSI gtx 970 supposed to be 60 degrees idle? I know the fans are not spinning before reaching 65 degrees, but the fans on my old gtx 660 ti where hardly spinning and idling at 40 degrees, should I be worried?
I was having this problem myself. I found that with MSI afterburner there is a button below the profiles panel "apply overclocking on system start-up. Uncheck this box and restart your computer. When idle now, my card runs at 135 Mhz 30-40 degrees idle . With the overclock applied on start-up it was idling at 1114 Mhz.
Also in the Nvidia control panel under Manage 3D settings, set Power management mode to adaptive.
