I just got the YLOD last night on my PS3. Maybe I should have been more proactive and cleaned the fan off. Every now and again (3-6 months) I would use canned air to spray out the vents, but that's about it. Now I'm staring at a brick.
Most people don't have the skills to crack open their PS3. I looked up some DIY info last night on how to do it and did. It wasn't that dusty actually. I've worked on PCs a lot and have seen a lot of dust caked to systems. My PS3 for not having been opened since bought 2 years ago was fairly clean in comparison. I think it has something to do with how the PS3's air flows through the case. It basically goes from front to back and the heat piping instead of finned heatsinks provides less nooks and crannies for dust to be caught in.
