I had to post this on other web-blogs because so many people are bashing apple about laptop heat issues: Note - Dell has the same issues; so it is not an apple issue
my blog -
Hey guys, before you bash apple for the heat issues with the macbook and macbook pro, one should really look at Intel for the problem - if the CPU is really the problem. First all laptops run hot, but I have been reading other blogs. There are postings about the Dell laptops running hot with the Intel Duo Core processors. why do you think there is a huge market for laptop coolers, oh and buy the way - those coolers really only help the bottom of the notebooks and the comfort level on your lap. Does nothing for the temp inside the machine - except maybe 1 degree (I have been looing at reviews for laptop coolers). Also, here at my job we may the stupid mistake a few years ago of buying Ezgo (similar to a mac mini, but totally tweaked out for the PC world - completely made from laptop parts) - I think they are now called Latte's. Anyway we bought them for business purposes to leave on 24 hrs a day. We destroyed about 100 of these due to overheating. Some were so hot, the thermal paste melted. You could fry an egg on it.
So bottom line: The more confined the space, the hotter. Laptops are really only made to be used for a couple hours at a time and not for hardcore gaming or maxing the CPU and harddrive use. Yes my company even made the mistake of buying an IBM server with a 2.5 laptop drive as the main hard drive - blew the drive in about 30 days.
also, as far as heat goes - look at your hard drive as a contributor. when my 5 yr old toshiba laptop is heavily using the hard drive (like when transporting large amounts of data from my desktop to my laptop) - the thing really heats up and my fans kick to high. does not heat up when using heavy applications. It then cools down when the hard drive stops being used heavily. Also, on my desktop machine, I have an IDE drive in an external drive enclosure. After an hour of just being turned on, the external enclosure is scorching. So as a rule, anything in a super tight enclosed area will heat up. It is the airflow internally that cooles things down. For years some people have also been complaining about desktop heat - that is why there is a huge market for custom cases and cooling products. Some people have even put bags of ice inside their desktops (yes that is even posted on some blogs).
So in closing - tight spaces, poor airflow, and heavy usage constitutes heat build up. Also, given the fach that Dell users are also complaining makes me think that Intel may have a flaw and the problem is INTEL, not APPLE. Or could it be we are just craming too much into a laptop as we are wanting them to be just as powerful as our desktops and looking to be as powerful as servers.....
Here’s a quote from a Dell Blog:

I have a question...my comp is running at 82 degrees right now (which is boiling), how do I turn my fans on manually? I checked the "fans always on" option, but they arent turning on...
Ive turned off all overclocking settings, and this is in its IDLE state.
I wouldnt' worry about it too much. Mine does the same thing. It goes to about 82 degrees and then the fan kicks in and it drops back down to 64. It just waits till it gets hot enough before the fan kicks in.
