I’m seeing temps max’ing out at 76C for the GTX1060 and 53C for the E3-1225. This is after running F@H for 12+ hours in a room that is around 25C ambient. Also, the 3x 92mm intake fans haven’t come in yet so there’s dead air below the GPU for now. I’m sure GPU temps will improve once those three fans are installed.
I’m not able to get a photo of my build right now but the attached photo shows the same internals except mine is a 1060 instead of the 1070. My GPU is also an inch lower.
I agree with WoodenMarker on this. Your temps are already pretty good. I'm not sure if more intake will have wanted effect. 65C max on GPU would be really good result.
