FADECs/EECs are not fail-safe, though. They may try to regulate too close to the limit, and dynamic conditions may result in transient exceedences.
Last week I had an engine overtemp (747, GE CF6-80) just after takeoff with an OAT of 35C. it was only 2 deg over limit for 2 seconds, but the EICAS dutifully recorded it and sent the message over ACARS. One of my colleagues had a similar (but slightly hotter/longer) one within a few days of that one.
