You mention, as some others have, that there is an overtemp condition under constant speed. What is running overtemp
Overtemp is typically caused by leaking oil from a bearing compartment directly in front of or aft of a disk. Evidence would be obvious to the investigator up close.
Since a recovered disk piece is now in the hands of the ATSB they would already know the difference between an overtemp or overspeed condition.
So watch carefully for a news release or find some pictures of the cavity where the disk ran
