I am in need of some advise/help. I have a Powermac G4 1.25ghz MDD with 9.22 and 10.4 installed on an SSD. When booting into OS 9 the case fans run; however, when I boot into OS X, the case fans start at full speed and then shut off once the system is booted. If I boot into safe mode, the case fans stay on and seem fine. I have reset PRAM, done the SMC reset several times, removed and reinstalled hardware components, etc, etc... It wouldn't seem to be a hardware issue, since the fans are running in safe mode, as well as OS9, but at this point, I am just baffled by the issue. I suppose it could be the PSU, but why does it work in safe mode and OS9? Just applied new thermal paste, with the same results. It seems like as soon as OS X is loaded, the fans gradually lose power, then cut off entirely. If anyone has some advise or suggestions on what I might try going forward, it would be greatly appreciated.
