Re: more on: Overheating problems with long continuous use?

"The high temperature of the case when you have it on a solid surface (other
than, say a lap or styrofoam) is indicative of a preferred 'heat path'.  I
used to do this stuff for a living at Compaq several years ago, so I won't
bore you with the physics, suffice to say that if the surface is even
moderately conductive (wood or formica) you will get better thermal
performance than just relying on free convection with the legs out."

Note however, that the bottom can get VERY hot indeed, hot enough to damage a
wood surface (I actually opened a small crack between sections of a maple
table). So use something protective if necessary between the TP and the
surface.
