In my continuing quest to soup up my G4 Digital Audio I'm considering changing out the 533 mhz single processor for dual 533s. Dual 533s are plentiful and inexpensive on Ebay, but I'm wondering about the heatsink and cooling for them. Pictures of dual processor digital audios(which have a different logic board layout from the "Sawtooth" boards and Quicksilver board) seem scant on the internet, so I'm not exactly sure what the correct dual processor heatsink should look like. I do know that the stock heatsink in mine overhangs the edge of the CPU card by a significant amount, so I'm wondering if, in fact, the dual processor heatsink on this particular model is the same as the single processor heatsink. If I can use the same heatsink, this seems like a good and cheap(~$15) way to boost the performance of the computer. Does anyone know any specifics on this particular upgrade?
