No offense taken if none intended 8o)

I have thus far avoided cracking the case (it's a euphemism) because of the 
law of unintended consequences (Murphy's Law tends to bite you when you can 
least afford to deal with it),  but I haven't even yet inspected the fans very 
closely. I say closely because I did perform a rudimentary check and there was 
very little dust accumulated on the blades. I'll get a baseline temp and then 
clean them.

I didn't chase that idea already because the system just recently started 
being temp sensitive and I thought it might be related to recent changes in 
the ACPI code from Intel.

I appreciate your suggestion.

I like the suggestion. I'll try it.
