I will look into all of those things Plec, unfortunately there is no space inside the case to fit any fans whatsoever. There is no fan operating on the right hand side of the case though, on the opposite side to the GPU. I will open it up and have a closer look inside later. It was a prebuilt system from overclockers. However putting new paste on the cpu will only solve half the issue but I will do that anyway. I am using a Reference edition 1060 unfortunately so the cooling on it is not great. It only has 1 fan which is to the front left of the side panel. If i feel the back left side of the case i can actually feel the heat so perhaps an outtake fan there would help cool the gfx card down?
Also how do I check what % the case fan is running at? Will that be in the bios settings I am guessing?
