    I followed the steps and initially it resolved the fan running.  After a couple of hours it started again.  Sometimes it is louder than others.  Like others, it is really taking a hit on the battery cycle.

     

    How is this going to be addressed with battery cycle counts?  Any other apple resolve?

    My Issue seems to stem from Safari and the Flash plug-in…I checked my activity monitor and Flash was using 136+% of the CPU. I quit ot of Safari and the fans are running at a whisper…I also istalled the Flash Blocking extensions in both Safari and Firefox that where listed earlier…

    I had the same problem Mac late 2010, 2.13 Intel core duo 4GB RAM 2

    Lion was installed as update.

    as result:

    CPU on 80 °C and to keep it between 70 and 80 °C fan had to work on 6500 RPM.
    I used Istat.

    repaired permissions, no result, reset the SMC and so on... no results.

    lately reading also other posts, I started to disable 1 by 1 the start up items.

    the antivirus Sophos +  the time machine auto back up -on off was quite successful

    now I have a 4000 RPM = quite decent as noise level and CPU at 40-47 °C.

    had nothing to do with the flash or browsing, mai land so on.
    Spotlight, yess is pushing the temp up, but is not running 24/7

    Check your startup items, the answer can be there

    Maybe helps

    Good luck!

    I have to agree, I wish I'd jave waited. Actually good I'm reading this though because I was kind of thinking it might be because my macbook is a few years old and can't hack it. If I'd have bought a new one and still got the fan crankin I would have been annoyed. Will wait for further releases I'd say. I gues no one who hasn't yet upgraded would be reading this, if you are ( which you aren't ) don't upgrade yet I'd suggest.

    Here is some additional information after I reset my SMC.  I am running on a Macbook Pro 2.1.  Resetting the SMC seemed to have helped a bit since it used to be especially bad after just leaving the machine for a while and it going to sleep.

     

    Now I notice it even when just using the machine with email.  I was not running safari at the time I noticed the problem again.  The AddressBookSourceSync and System Preferences apps are running at between 60 and 70 % each which is my my CPU temp is very high.  I have seen it in the 170s and it has never been that high before.  I am afraid of what running it this hot for a long time will do.

     

    I quit the System Preferences app that I had running and that helped, but the AddressBookSourceSync is just out of control, exceeding more than 70% and I think it should have finished its major work when I moved to iCloud yesterday.
