this sounds very normal to me. I clean my desktop every two months of operation.

A drop of 10K is normal just for blowing the heat sink.

The best design of a notebook I every have seen was my old Fujitsu. I used it from 2004 until the beginning of the year without any cleaning and any problems with dirt. After it was dead I disassembled it and did not find any dust blocking anything.

This switch might always help. I did some tests more than a year ago. I left the BSD Scheduler then on the single core Fujitsu notebook mentioned above but used the new one my desktop machine.

It will also depend on the software you are running.
