Hmm, no. I am saying that I would like the reading to be correct. I have 
measured the outside temperature of the case with an infrared 
thermometer [1] and found it to be higher than the readings returned by 
the coretemp module. In all other CPUs I have, the coretemp readings are 
higher than the case temperature.
