I think you could check with Apple and see if the excess heat is
from a design defect. 

A few month's ago, I bought a Sony 19" Trinitron.

First I noted a burning semi-conductor smell. 

Next, the RGB colors started diverging by about two inches. 

When I found that my Trinitron was assembled in Mexico,
I took it back. Unlike the Japanese manufactured Sonys a lot of
my buddies have, the Mexican set appeared to have an electronic assembly
problems.

Then, back at work, about three months ago, 
we got two new Apple 13" RGB (Manfactured by Sony.)
Although these units are marked "Made in Japan", they began to
exhibit the same burning semi-conductor smell. (May be the internals
are assembled in Mexico?) After about an hour of use, the colors 
begin to diverge by about a milimeter, not enough to warrant interrupting
development by several days on order to take the monitors to the shop.

When we compare the new monitors to an identical monitor we have in
the lab that is over a year old, we noticed that the new screens
have a bluish-white tint instead of the greenish-white tint of the
older model. The new screens are noticeably hotter. However, the
line that separates the two pieces of the mask at the lower third
of the screen is less visible on the new models that on the older model.

If we compare our MacII that is over a year old to the new one's:

The old one has a Sony made power supply; the new ones have 
ASTEC (Taiwan?) power supplies that make more noise. 
However, the old MacII has a 5.25" Quantun
HD40. The new ones have 3.25" HD40's that are less noisy and 
noticeably quicker...
