G5 fan on high, then freezes???

[Sofa King]

Hello all,
im posting about recent issues with my G5 DP 2GHZ.
My rig has been fine since day one, but since I changed my system drive, and added a second drive, the fan radomly goes into a crazy high speed mode, and then locks up, requiring a hard shut down.

heres the facts:
*my os is 10.4.9
*2.5 gb ram
*used carbon cloner to copy my original system disc to new Seagate 7200.11 1 TB drive
*installed second 1TB storage drive.
*both drives divided into 6 partitions.
*both drives formatted OS extended [Journaled]
*jumpers are in the correct position
*drive firmware is SD15, the correct, and most current
*drives are set to never go to sleep
*fan/freeze is not task specific, meaning it will lock up with no apps open
*this fan/freeze is sporadic, and has happened three times in the last 4 days.

ive attached the system log.
I know nothing about these logs, so my apologies if Ive included too much, or not enough data.

The most recent crash, was at july 14, at 4:10 pm.

thanks for the help.
all the best,
Sean

Sounds like on of your CPU's overheated.

I hope you have Apple Care.

Hi,
Thanks for responding.

what makes you think that the CPU is overheating?
Was it something in the log?

I ask because, this computer is, and has been, and a VERY cold control room from day one.
And the fan does not ramp up, then freezes, it seems as if the fan ramping up is a result or by-product of the freeze, not the cause, but I could be wrong.

thanks,
Sean

I am sofa king we todded 😱

Thats what happened to mine it started sounded like a jet.

Either that or one of your thermo sensors is broken, but that would not lead to a crash.

ALSO

Make sure the clear plastic air flow cover piece is in correct.

Set the power/performance to normal.

Reinstall the OS.

It happened on a dualcore G5 of mine, just tonight, in Tiger.

I upgraded to Leopard and no issues.

Or just reinstall Tiger. Google around; I think the freezing thing is a known issue.
