    I have been concerned about my macbooks temperature for some time now, but after extensive reading, I have found that a temperature of 70°celsius should be no problem.

    I have just started compressing some movies with apple's compressor(Final cut studio). I saw the temperature rise until an average of 82°celsius. So after the job, I decided not to try this again. I don't want to fry my laptop. I am aware that it can go up to 100°C. But hours of working at 80+ can't be good for the components.

    I have installed FanControl and I was looking at coolbook. Though, I was hoping for another solution. If there is any application or setting that will let me limit the CPU usage for Compressor, It would result in a longer, but cooler comperssing process so i don't have to wory about the computer and i can even do some other stuff like browsing the internet.

    I don't care if the compressing time doubles. I just want to have control over the CPU usage of my computer.

    Another note: Everyone knows Flash player for mac still doesn't work properly and can force the CPU to 70°C. With such a limitation option we can make it again safe to browse the web :)

    Let me know your thoughts!

    I can only say 100 days (2400 hrs..) played World of Warcraft, @ 80°C ++
    I have also used my machine for a lot of movie ripping, film editing compressing DVDs.

    Don't worry!!

    Get rid of the temp monitoring app and SMCFanControl. You'll have much less to worry about... ;)

    Seriously, though - it's made to operate in the temp ranges you're experiencing (80c+). If for some reason it gets too hot (something set by the design engineers at Intel and Apple), it will throttle back or shutdown. It will only get too hot if the fan quits; air flow is restricted; or machine is operated above the ambient temperature recommended in the MB/MBP's user manual.
