RE: Probem involving irregular Fan speed-ups that now occur
after having upgrading from OS X 10.3.6 to OS X 10.3.8:
This is apparently a problem that has been experienced by other
users but I have not found a cure in my case. I had never had any
previous similar problems with my G5 hardware -and specifically had
never had any problems with the Fans since owning my G5 until I
upgraded from OS X 10.3.6 to OS X 10.3.8.
Problems Description:
After upgrading to 10.3.8, after startup, the Fans rev up to an
unnecessarily high speed on boot up -and remain noisy for apparently
no reason. The fan speed-up is unrelated to any CPU intensive tasks
-since only the OS and minimal tasks are active.
My Diagnosis:
Since the problem goes away temporarily when I log into
-and then out of- another administrative user account, I am
convinced that there is an Operating System bug related to
the interface of the OS X 10.3. 8 Upgrade components with
the G5 hardware.
My Attempts to Cure Problem:
I have tried RESETING the Hardware PMU Switch (Power management Unit)
several times (on at least 5 separate occasions). This only temporarily
cures the problem, which comes back right after the next boot up.
The G5 is no longer the silent computer that it was and the fans themselves
are adding unnecessary heat due to irregular operation.
Also I have tried an Open Firmware Reset, and do all of the usual
Parameter Ram Resets on a regular basis on boot up, as well as
Repair Disk Permissions (also before and after the last upgrade).
I have not yet tried to upgrade to OS X 10.3.9 -because I would
like first to understand this problem or to know that such an
upgrade would cure the problem (?).
I have tried asking AppleCare about the problem; however,
no Apple support rep seems to be able to comprehend the nature
or fundamental method for curing a problem that was created by
this "suggested Apple upgrade".
Your help sought and greatly appreciated.
Thank you.
