Hovering is fine but it doesn't really clean the heat sinks or the cpu heatsink behind the cpu fan or the power supplies with massive heatsink inside and the two fans that are coated with compacted enbedded dust. How about those dust bunnies that live in the floppy or optical drives or the ones trapped between the cracks of the plastic case. If you think a hover no matter how strong works fine then try my method when you are done with the Flintstone elephant or was it the woolley mammoth and blast away with air. 15 years ago I was concerned that I might blow away a jumper or something else attached to anything that could be carried away on a jet stream... This has never happened (yet!) but I am always watching just in case. I have a single dive tank that is light enough to travel with. Your point about the asthmatic is excellent which is why you never do this in the workspace but outside where the people with the cancer sticks go or the goods inward bay. I am done in less than 5 minutes. People who watch what I do for the first time always seems to be impressed. Again when working for One self and not a company impressions are important when on site and a big yellow tank makes an excellent conversation piece! And those of you mad things out there that do case mods there is no equal way of getting rid of those little conductive metal pieces.... Dive bottles also have clean air which is very important in our line of work.

Hi. The above answers are partly correct, but the air next to the blade has a non-moving boundary where the air does not move. Any dust that settles there will stay until the blade is dusted.

Fans have to attract air in order to blow air. Static electricity, or dirt already on the blades, will cause dust buildup.

First they collect oil vapor droplets from cooking etc.
Then they come into contact with a lot of air which has suspended dust particles, it sticks to the oil.
Voila!

Cirric hit the nail on the head.
All forms of fluid mechanics are subject to the "no-slip boundary" condition.

ceiling fans usually get dusty on their tops because they suck air downwards onto themselves
