The overheat warning on the hub 3 is a known issue with some batches of hubs.
However, as this may mask a real problem which could be a fire risk the policy is to replace them.
If you have done a reboot & it has not resolved the issue the Forum Staff here can arrange a replacement.
I have escalated the thread to the team, who should respond shortly.
