Late-2008 MacBooks: Fan noise
Users are beginning to report excessive fan noise emanating from Apple's Late-2008 MacBooks and MacBook Pros. One MacFixIt reader writes:
"The first day with my 2.53 GHz unibody macbook pro all was silent, after a day the top left fan is now making a lot more noise all the time and can clearly be heard. I have read on macrumors forum and apple forums of a few people with similar issues."
Excessive fan noise can be caused by spiking processor usage and various other factors. See this tutorial for more information on killing hung processes cthat can inordinately spike processor usage. In some cases, simply killing a process and allowing it to restart will alleviate the issue.
Apple issued SMC updates for the previous generation of MacBooks that dramatically reduced excessive fan noise.
Though not a viable long-term solution, some users have found that turning off one of the MacBook Pro's processor cores eliminates that noise.
In order to turn off one processor, you need to install Apple's Developer Tools (from the install discs included with your MacBook). You will then have access to a System Preference pane labeled "Processor" that can toggle between single and dual-core operation.

If your notebook is typically used in a fixed location for much of the workday, consider using an aluminum stand & bluetooth mouse/keyboard; I prefer the models which allow air to circulate around the bottom, rather than those with embedded fans - which actually contribute to the very problems they're intended to alleviate...

Or it could be a defective fan. I had to have a fan replaced in my daughter's MPB about a year after we bought it. Don't know if the new Macbooks use the same fans however I'd bring it in if under warranty if all else is not working.
Mr. Rhodes, the new MBP still exhausts out the back. I'm not sure how you have determined it's exhausting out the speaker grills. The right side speaker has the optical drive under it. There is certainly some air movement, but that's not a primary outlet, the holes are simply too small and easy to clog with dust. They do allow air in however since dust is more easy to remove from the outside than the inside.

The heat pipes lead to the back of the machine to the main radiating elements and the fans push out through them.
