Without repeating this as an experiment it would be conjecture or a guess.
But it is well known we want to keep it dust free and do the canned air every 6 months or less.

Yesterday my laptop shut down 3 or 4 times b/c of overheating. I looked in this forum and found a lot of advice to take it apart and shoot compressed air around, which I did. Its been working fine ever since.
There was a lot of dust on the grate over the internal fan. Just as I was putting it back on my cooling pad, I noticed that there was a lot of dust on the grate over the two fans in the cooling pad. I shot compressed air into them, and I couldn't believe how much dust shot up into the air.
Now I'm wondering---if anyone can make a determination--which is it more likely to have been--the dust over the internal fan, or that covering up the cooling pad? The reason why I'm asking, is that it is much easier to grab a can and shoot air into the cooling pad, than taking apart this laptop and then hoping that Humpty Dumpty has been put back together again when you are done. I can quickly clean off teh cooling pads every month or so if that would do any good.
I did notice yesterday that the cooling pad itself seemed just as hot, if not more so, than the part of the laptop where the CPU/internal fan is.
I'm wondering if all that dust in teh cooling pad was what was causing the overheating in teh laptop itself, or not.
