Most definitely. Although the form factor of the processor card is the same between single and duals, and the bottom side is the same, the placement of the PPC chip or PPC chips are different, so the top side is quite different. A single processor heat sink has the provision for one centrally located processor. A dual processor heat sink has the provision for two offset processors. The heat sink mount is the same. A single processor heat sink will not cover the two processors on a dual processor, and this is a known fact. A dual processor heat sink possibly could be modified to cover a single processor, but this is conjecture. The "raw" (i.e., unpopulated) dual processor boards are identical between the QS 2001 dual 800 MHz and the QS 2002 dual 1000 MHz, however the boards are stuffed completely differently because of clock generator and processor voltage regulator differences. I would, therefore, expect that the heat sinks would be the same between the QS 2001 and QS 2002, within single and dual models. As always, the PPCs are run so very hot that it is important when dismounting a processor to keep its heat sink with the processor. -- 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.
