Some CPUs (the PB1400 CPU comes to mind) are fitted with a thermal pad that is supposed to conform to the heat sink. I have seen some CPUs (e.g. - G3 processor upgrades) delivered with a tape-like material that is supposed to soften/melt to fill in gaps between the processor and the heat sink. I'm not convinced that the product that was used in the upgrades I got really did the job. For reference, I did some searching and came up with this: <http://www.amazon.com/StarTech-HSFPHASECM-Thermal-Heatsink-Alternative/ dp/B0009B0K2I> I would clean it off as much as possible (alcohol) and use a proper heatsink compound to do the job. Use a very sparing amount of a good quality heatsink compound. Internet searches tend to come up with a brand called 'Arctic Silver', which I have not used myself. Hopefully someone more expert in this field will chime in. - Don --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Books, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
