Ensure the device is properly ventilated and there is no dust in the fans

Verify the traffic going through the firewall at that time, was the load unexpectedly high?

Was the datacenter room temperature unusually high during that time?

Also make sure it is not sitting on top of a server that was running very hot and "cooking" the firewall
