Thus I think the problem lies in the soldering; the lead-free BGA solder has become flaky. Heating it with the hair dryer seems making it stable again (for a while, at least). Of course, the high temperature of the chip - and consequent stress - only makes the problem worse. > Check the heat sink and make sure it's not slipped off.

Good advice but, as I said before, I consider disassembling the G5 my last possible chance. Since right now it's working (thanks to the "hair dryer trick"), I don't want the burden and the risk to disassemble it and - maybe - break something else. :-/ I was looking for an advice to improve the U3 temp, *without* disassembling the whole shebang. :-) -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
