Eliminating the Power Mac G5 beeping noise using CHUD

David-James Fernandes reports a solution, corroborated by other readers, for eliminating the beeping/buzzing noise that seems to be generated by the Power Macintosh G5 Dual 2 Ghz's processor slewing function.

The solution requires that you download Apple's CHUD tools, which are available from ftp://ftp.apple.com/developer/Tool_Chest/Testing_-_Debugging/Performance_tools/CHUD_3.0.0.dmg.bin.

After installing CHUD, go to System Preferences, open the "Hardware" pane and turn off "Nap".

Apparently this option turns off the G5's ability to use processor idling, eliminating the beeping noise.
