    Mine's always pretty hot TBH. It freaked me out a bit at first, I even took it to the Apple store but I've never had a problem.

    when im running adobe photoshop & dreamweaver, itunes, safari, ical, adium etc on my 2ghz 1gig macbook its reached 90+ degrees C. the backs gets so hot i cant hold my hand there for more then a second.. I think its because my rams so low and its basically running off my disk..

    65 although really warm, isn't anything to worry about

    You're fine as long as you don't combine heavy CPU usage and nudity... lol.

    I'm at 62 right now just on FireFox.

    What a relieve I thought maybe the fan was broken, because compared to a windows notebook the macbook is really silent
    Oh and it is not to hot on my lap, just warm which is not bad at some cold times

    OK... I was worried there.

    I am just getting a new MacBook 2GB RAM (in transit from Shanghai right now) and was worried it was going to burn through my pants (not really).

    What you would feel on the lap is less hot

    A few hours ago, I ripped a DVD and my CPU A reached 68 degrees in an air conditioned room and I'm using one of those stands that elevates the back of my Macbook. I felt the back and it was just warm but not uncomfortably hot. Maybe this temp (65-70 degrees C) is nothing to worry about?

    Anything within the range of 65-80 degrees celcius is within acceptable levels if you're under a full load. Obviously, room/ambient temperature is going to weigh in quite heavily on that estimate. Just look for performance anomalies -- if your display starts producing artifacts or your system is starting to exhibit unusual behavior, then I'd be a bit concerned; if not, then I wouldn't worry about it.

    The following is taken from Intel's thermal and mechanical design guidelines and support manual. The numbers are Intel's recommended maximums. Don't worry too much about it, just get Apple Care and you are covered for 3 years if the proc fails.

    Edit: Sorry the previous table was for desktop procs, I didn't pay attention to which doc I was opening and I didn't proof read before posting. The following is from Intel® Core™2 Duo Processor for Intel® Centrino® Duo Processor Technology Based on Mobile Intel® 945 Express Chipset Family Datasheet. Section 5.1
    normal operating temperature range of 50-100 °C
    It goes on to say this.
    The processor supports the THERMTRIP# signal for catastrophic thermal protection. An
    external thermal sensor should also be used to protect the processor and the system
    against excessive temperatures. Even with the activation of THERMTRIP#, which halts
    all processor internal clocks and activity, leakage current can be high enough such that
    the processor cannot be protected in all conditions without the removal of power to the
    processor. If the external thermal sensor detects a catastrophic processor temperature
    of 125°C (maximum), or if the THERMTRIP# signal is asserted, the VCC supply to the
    processor must be turned off within 500 ms to prevent permanent silicon damage due
    to thermal runaway of the processor. THERMTRIP# functionality is not guaranteed if the
    PWRGOOD signal is not asserted
    Hope this helps to clear up any confusion!
