    Good point. It is better to let your warranty expire before getting it serviced. The $600 you spend for a new logic board will contribute to a robust economic recovery in the new year.

     

    Warranty do not expire for another 30 months...

    I have now stess tested the setup (with QuickTime player removed and the scmFanControl running).

     

    Strangely enough the CPU usage are now overall reduced by a huge factor.

     

    I started one Virtual Lion session, one Virtual Mountain Lion session, one Virtual Linux ubuntu session and one Virtual Windows XP session..

    With all of them idling (including the Mountain Lion base system) the total CPU load are 5% and CPU temperature 50 degree Celsius. Running an autoruter (a huge PCB layout) in the Windows XP session increases the total CPU load to 15% and CPU temperature to 65 degrees Celsius..

     

    Previously this would have caused problems after a short time due to high CPU usage and high temperature.

    And everything now loads faster including Windows apps.. It feels like the MacBook Pro have become 3 - 4 times faster and uses 1/4 of the CPU resources to do it...

     

    So I am in no hurry for any hardware service.

     

    Also WiFi speed have increased with 50% (practical datarate)...

    Was even able to create a CPU overtemperature kernel panic with a virtual 10.8.2 session (parallels).

    This has QuickTime installed and I started QuickTime (error message due to emulated graphics) and 20 seconds later the CPU temperature was above 90..

    A new kernel panic on first reboot also because of CPU overtemperature.

    On the second reboot the CPU temperature was down to 80 and was soon cooled down to 40 again..

     

    The log file indicates that Parallels was the cause of the kernel panic in the first reboot, but what I now have seen several times are that when the temperature creates a kernel panic the last properly accessed app or kext get the "blame".
