Heat has always been the bane of mobile
computers. From chassis design to hardware engineering, much effort has
been made to drop operating temperatures by a matter of degrees. The
latest Intel-based MacBooks, however, seem to be taking a step back
with reports of unusually high heat signatures.
After
some investigation, it seemed the high temperature was due to the
plastic film which covers the rear exit vent. Used during
manufacture and delivery to prevent dust from entering the system,
Apple, in an article
on its support site, recommended that users discard this
layer to allow hot air to circulate out of the system. Moreover, the
Cupertino company explained that "with processor and bus speeds in
portable computers often matching, if
not exceeding, those of desktop systems, increased operating
temperatures in portable computing products are common throughout the
industry". In other words, please don't use laptops on your laps
anymore, unless receiving third-degree burns on your quadriceps happens
to be a hobby of yours.
