When my G5 was repaired by Apple they forgot to do the thermal calibration, and I had to take it back. It cost me another week without it. Needless to say, I decided this was something that I didn't want to happen again, so I searched out ASD discs. I can't say I ever really necessarily found the correct version of ASD for my Early 2005 G5 because I wasn't ever certain which version was correct? I did boot at least one or two ASD versions, but I never saw any "thermal calibration" software? Also I was somewhat confused about these discs, I think they were dual boot discs, and you needed to hold some key(s) to get it to boot one way or the other? I can't remember if the Option key boot gave you all the choices, but I remember being somewhat unhappy that I couldn't locate said thermal calibration software. If anyone has experience doing a thermal calibration on a G5 could you enlighten us please?

On the ASD disc that I have there is an os9 style boot of sorts and an osx style boot of sorts. the x style boot is just for testing certain aspects of the hardware. The more conventional boot has all of the diagnostic utilities and under one of the menus up top, it has an option called thermal calibration. Run it and it will go through cycles for each processor and calibrate the fans.
