Hello MOS users, I need your help about fan of my Mac Mini G4 (silent upgrade version). When I insert the AC power cord the fan start to run at max speed without power on the Mac. Once I press power button both OS loads (I have a dual boot MOS + Leopard) and runs without any issue.
The fan noise is very high and I wonder what caused this issue (maybe some HW fault?) and how can I fix the issue. I hope there's some trick I can do to fix it under MacOS/MOS or Open firmware.
