To ensure proper fan and temperature control in the Power Mac G5, you must run Apple Service Diagnostic whenever you replace a processor or logic board with a new processor or logic board. You must also run the diagnostic if you re-install the same processor but in a different connector from the one in which it was originally installed. Apple Service Diagnostic for Power Mac G5 is available as a download from http://www.info.apple.com/discimages/.
Note: The calibration process of Apple Service Diagnostic requires a controlled environment to ensure accurate ambient temperature readings. Computers under test must have the transparent air deflector installed and the door sensor switch must be operable. Units under test should also be located away from heating and air conditioning ventilation systems and the fan exhaust of other machines. Ambient temperature should not go above 77 degrees Fahrenheit or 25 degrees Centigrade.
