Of course, you may have already done this. 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.
