    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 :eek:

    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.
