boon Posted February 4, 2009 Report Share Posted February 4, 2009 hey guys, Recently, I am planning to do copper mod on my XPS 1530. However, i am facing problem in getting copper sheet because it is too expensive. they only sell it in large piece of copper and i only need to small amount from it. As a result, i want to replace the copper sheet with aluminum sheet. But i am worrying about the unpredictable problem.Below is my worry: 1) The copper heatsink is connected directly onto the GPU. There is just thermal grease between GPU and copper heatsink. Not thermal pad. So if i placing the aluminum between GPU and copper heatsink, does it decrease the thermal conductivity? It is because the originally the GPU is directly connected to copper surface of heatsink. If i added aluminium betwwen the copper and GPU, the GPU will contact will aluminium surface. So i worry that it will decrease the thermal condutivity since aluminium has smaller conductivity compared to copper. 2)Is there any air gap between heatsink and GPU since there is only thermal grease between them? Is thermal conduction will become better if i add aluminum between heatsink and GPU? thank in advance. Quote Link to comment Share on other sites More sharing options...
