    How hot do MBP models get when used for graphic intensive situations? My HP reaches 88 deg C, and sometimes it powers off instantly. Any users seen situations similar to mine (more importantly, powering off)?

    Never seen it power off, nor heard of it happening, even with temps approaching 100C. Mine (i7 15") will get pretty hot running intensive applications on default fan settings (sometimes CPU temps can go over 90-95), but downloading a small free app called smcFancontrol allows you to turn the fans up earlier and avoids any significant heat issues. Generally when the fans are on nothing I have done (including games and chess programs that run the CPU at 100% for extended periods) causes the temps to stay above 80C or so.

    Even when it runs hot, it remains cool on top and on the trackpad, although the back bottom of the machine can get toasty. I find it manages heat better than any similarly slim wintel.

    Overall I do not find that it has any significant heat issues that can't be solved by manually turning the fans up. You will find reports on the internet of internal temps reaching extremely high numbers; in general this happens because OS-X does a poor job of turning the fans on in time.

    I think the MBP has always been one of the worst notebooks when it comes to heat dissipation. I have owned every gen except the iCore.

    Like most notebooks, the CPU and GPU temps under load get pretty close to the safe maximums in my experience. But the heat radiating off the body is a real drag.

    I went to apple store and check out the MBP 15" i5/i7. CPU temp are in the 50 range. It doesn't exceed the warning temperature by all means, but it is not what I prefer to have in my laptop anyway.
    If you are concern about temp, go for Sager, they have the best cooling system . However, you dont get the sleek and thin design of the MBP.

    I haven't heard of any heat issues with the newer gen MBPs. With the older gen you had to worry about the 8600 dying over time.

    Other then that, I wouldn't be worried about the temperatures. My MBP has seen a LOT of hot temps, and it still chugs along.
