If you can get an original plate that would be best. Did the original use a heat pipe to the fan sink, like the Pismo? If so, you must get an original.
Little point second guessing cooling that already works. If no heat pipe, and you can't find an original, you could fabricate one based on the original design.
For materials you could use aluminium, copper or brass.
Instead of machining one from stock, it might be easiest to find a heat sink that nearly matches and cut it to shape, if it is finned.
Good luck, & let us know how it goes.

I need suggestions on what material and thickness the cooling metalplate
that is supposed to be on top of the 500 mhz G3 Powerlogiz Blue chip for
the Powerbook Wallstreet model ( I have a rev. 2), should be. I just
bought one second hand and it seems to be missing from the package and I
have to make my own. I have access to a toolshop, so it shouldn't be a
problem, but I could use some info if you have one or have knowledge of
how the real thing is supposed to look .
Steel comes to mind as being the most "cool" metal I know of. Is that a
good material or should I use something like brass or some other material
instead? I'm contemplating 2-4 mm thickness, but if you guys have any
real info, I'd be glad to hear about it.
