Restore normal fan operation on an iMac G5
Authored by: Raven on Mar 09, '06 06:22:04AM

I actually did check with Apple while I was traning there a few weeks back. I had to enter Single User Mode on a G5 dual processor tower to fix and issue and obviouslt every one in the class "kind of" noticed the full blast fan noise in the quiet room.
Since it was the first time I had to boot a G5 in Single User mode I was surprised myself, so I asked the trainer. He said that by default G5 towers and G5 iMacs will runf ull blast in Single User mode as power management/temp monitoring don't load if booted this way, so, to prevent issues, they added info on the ahrdware to run at full capacity to make sure that the machine would not overheat even though its not being monitored. So it IS a feature... Just that it look slike there is a way to get around it... but wouldn't run processor intensive tasks in SUM with this diosabled as even if the processor starts heating up, the fans probably won't pick up speed.
