I see!!!
Well I just got a block of Copper to work with and it was sheer torchure on my Mill but I got a Copper block Milled out now. I am going to have to rework the CNC code to make it easier on the mill.
The rest of my stock should be here Friday. I will post pics of the copper block on my website and i will be testing it that same way I did with the Aluminum one to see what different temps I can get between the two blocks.
I think I may have found a flaw in my last testing aswell. There was to much airflow around the back of the motherboard which may have caused lower temps. I will retest each block better this time.
