It isn't accurate... It can sometimes "approximate" cpu temp well.
The type of sensor on hte kt7a and other socket-a mb's is typically the socket-thermistor, and while measures can be taken to improve "accuracy" problems still exist.
Warcon,
no, it is not "much more accurate"... it is slightly warmer readings, but should not be confused for accuracy, since it is still highly inaccurate.
