All right. So I've scoured the internet, and though places like XLR8Yourmac have been useful, I still don't know what size O-Rings to use, nor am I entirely sure what tools I'll need to disassemble the LCS. It's a single-pump Delphi, by the way. As far as I can tell, there are no leaks; the computer runs fine, except that if I run it at 2.5 GHz (vs. "Reduced" in Energy Saver, presumably 1.25 GHz judging by the benchmark scores....) it overheats to over 200F almost instantly and hard freezes. Thus, presumably, something has gone awry with the LCS, be it a clogged tube, or dried-up coolant. (I can actually hear the liquid slosh around in there sometimes, which shouldn't be the case.) Obviously that's a bit of an issue for me, and while a quad 1.25 GHz G5 actually isn't half bad, I'd really like to be running comfortably at full speed. Anyway. Does anyone know *exactly* which tools I'll need? I unfortunately don't have any hex screwdrivers, or even torx. I'd love if someone could link me, if not, simple descriptions would be great too. I know what to do when I have the tools required, and I know what coolant/etc to use, I'm just stuck on how to take it apart.. and the O-Ring size to buy as well. Thanks in advance.
