Thanks for explaining the version. That makes sense.

The thermal grease has not been in place for a 12 month yet, but it is
always a possibility.

The heatsink and fan have been blown out; along with four of the
exhaust fans.  Temperature sensor is reporting below 30 degrees and the
system is idling with no load.

I've disconnected the drives and will try to get a version of FreeNAS
running from memory stick to see if it remains stable ... in lieu of
replacing the paste.

Many thanks,

Michelle.
