Your mileage may vary, but this is the same behavior my MDD (same specs as
yours) exhibited a couple of weeks before my processor card went up in
smoke. Hindsight tells me that I should have pulled the heat sink off,
cleaned the old thermal paste off, and apply new paste. After the
unfortunate event, I did a postmortem and found old, dried out thermal paste
that couldn't have possibly been effective anymore.

This is not to say for sure that this is what's happening to your machine. I
just wanted to share my experience for you and perhaps give you something to
try that may be effective.
