Internal heat sink for all models of PISMO PowerBook G3. The PISMO PowerBooks can be identified by the FireWire ports which none of the other PowerBook G3's have.
This part screws onto the top of the processor and cools it by transfering heat through to a secondary plate which is cooled by the main fan.
To function correctly, the heat sink must have a good thermal seal with the processor which can be achieved using thermal paste available from the tools section.
This is a used and tested spare from a recycled PowerBook.
