[ydl-gen] Noisy fan on Power G5 and YDL 6.2

[Chris Urban]

What you're describing is the fan running at full speed - which you can
Replicate by booting the Mac into the command line and running fsck. 
There's likely a software patch that addresses this directly.

You need the fan to run as set at the factory to control the temperature, so if the fan is too loud, look for replacement fans that are quieter.  I'm very puzzled as to why Apple chose to put noisy fans in the powerbooks.
