Ok, right now I don't have a MacBook Air to play around with... but has anyone thought of doing a mod to the actual heatsink for better contact? I remember on my old Dell Inspiron 8600 Notebook PC, the ATi Radeon 9600 card constantly overheated due to bad heatsink contact. The fix was to use a piece of copper plating to add more mass + better contact for the heatsink. Since the air is thin, it is impossible to add a large piece of copper plating, but there are thin, maybe 0.13?mm thin pieces that can be added onto the CPU and Chipset using Thermal paste as a center gap for better contact. Anyone think of being the guinea pig to try this?
