The mac web has taken note of an observant MacBook owner who found at least part of the reason why his MacBook was running so hot. Apparently, some MacBooks are shipping with the rear vent (between the base and the screen hinge) blocked by a piece of plastic. Removing the plastic allowed air to circulate correctly and lowered operating temperatures dramatically.
While some users report having found the plastic, others report not finding the plastic, so mileage may vary.
Meanwhile, due to the controversy surrounding the excess Thermal Paste, MacDevCenter disassembled their MacBook Pro to see if reducing the Thermal Paste would indeed cause a significant change in the running temperature. Contrary to other anecdotal reports, they found there was only a 2 degree difference in temperatures before and after the extensive disassembly.

So in conclusion, MacBooks just run hot....sorta like how my car's temp guage gets into the red when it's idiling on the freeway while I'm stuck in a traffic jam, the only difference being that MacBooks aren't supposed to come off as 14 year old pieces of crapSeriously Apple, I sure hope you get all these heat/moo/whine/display issues figured out before I start looking to get a MacBook (pro) once Leapord is out.
