Riba, et. al. I think your suggestion does make a lot of sense. I do have an NVidia 2MX as graphics card. I still can feel that the fan from the CPU upgrade doing its work, but you might we right about the fan of the graphics card. Is there any way to verify that this indeed the problem without dismantling my Cube (e.g. is there some software that can run a test on the graphics card and figure out whether something is wrong with it)? And if something is wrong, how hard is it to get a replacement?
