Hi! I'm in the process of moving the contents of a 2008 chassis to a 2006 one. This involves some modification, but it seems doable. I'm now ready to remove the Logic board from the 2008 machine, but the heatsinks for the two CPUs needs to be removed first. I unscrewed them, and got surprised by the silver liquid-ish goo underneath (liquid metal?), and a square gasket of some sort (with grease to avoid shorts?). I read through some manuals, and found that this is special for the 3.2Ghz, and that the heatsinks shouldn't be apart from the CPU in more than 30 minutes, so I just mounted them straight back on, without removing the board yet. No manuals stated anything about removing it, reapplying etc. What do I do from here? Is it reusable? Not supposed to be replaced with my normal "Noctua NT-H1" thermal paste? What about the gasket etc? I didn't expect any problems with this, but I guess this Mac is a bit more complex than typical machines.
