you are welcome. I know what you mean, something must have aged to cause the increase in operation temp. In the case of MB tho the CPU is soldered onto the motherboard. I know, it's one of the most useless inventions. I mean it does make the notebook super thin, which fits Apple's marketing agenda, but i wouldn't mind having the ability to install a new cpu, or in your case reapply newer cooling cream.

also, I am not too sure if the fan loses efficiency over time? I know it's at 6200RPM but numbers could be deceiving. what you think?
