I recently experienced this in a way. My laptop was overheating a few months ago and finally a BIOS screen said that the fan was not working. I had also as usual used up all my meagre "runway" working on my "startup" and had to immediately pick up a new contract. So I panicked a bit and just got cheap Chromebook. Because of having both projects and needing to put a lot of energy into the contract, I assumed that fixing the laptop was going to be too involved. So I kept deciding "I don't have energy for it this weekend". Turns out, all I had to do was remove the back cover and then the heat sink. And then pull/blow out the piles of furry dust out that were totally blocking the air flow. I didn't need to buy or replace a fan and I already had the correct screwdriver (which I had assumed I needed to buy a new one along with a fan). I guess the point of the story is that after a certain amount of time, people might want to clean their laptop intake vents or open it up and clean inside in that area.
