Thank you.

I can probably learn how to do an internal cleaning here on Ifixit.

I also notice that my L3 Cache does not show up in the system profiler.

Here's how to get to the heat sink, fans and rear vent to clean them out, you may want to reapply thermal paste at this time: PowerBook G4 Aluminum 17" 1-1.67 GHz Heat Sink & Fan Assembly Replacement

Here's the paste I use: Arctic Silver Thermal Paste Here's a generic guide on doing it: How to Apply Thermal Paste
