The reason I started doing this is, as you pointed out, over time you
build up dust and the cooling becomes less effective.
This laptop is over 6 years old and I used to just leave it on 24/7. I
started shutting it down because I was concerned the cooling probably
wasn't as efficient as when it was new. But, so far, no problems.

How much dust ingestion are you going to get on a decently built laptop?


After 6 years, quite a bit as I found. I didn't take it completely apart,
but enough so to expose the CPU, heatsink, fans, etc.
This laptop has 4 miniature fans. I was surprised at how much dust had
accumulated.

Don't try to being facts into this discussion. Did I tell you about the
time I was at the Apple store. The tech was pulling apart a computer on
the retail floor, and it had next to no dust. Laptops are not used in
dusty environments, so they don't ingest as much dust as regular
computers. I think it has something to do with Newton's 3rd law.
