The consensus in the Mac underground is that all the heat problems are related to massive quantities of heat grease, and that the noise problems are caused by the fan being on too much because of the heat problems.
I've read that all it takes to fix both issues is to scrape off the heat grease and re-apply the recommended 1/20th amount. If I had the money right now to be buying a new laptop, I'd probably get a MacBook and take the machine to a PC shop to have the heat grease re-applied properly. The machines seem to be completely awesome apart from this little issue.
