Hair dryers are meant for drying hair. If you want to dust your case and you don't have access to a can of compressed air, either use a soft bristle paint brush(one's that painters use) or a blower or both. Make sure the case is disconnected from the wall and it's grounded to avoid any static build up. Do not make the fans move with the blower, they will generate power. Disconnecting them would be a good idea. Removing them would be better to get to those dirty/dusty areas.

I had never heard this, or experienced issues from doing so. I use a leaf blower on my PC roughly bi monthly according to use and it's never caused any issue (that I am aware of). I can understand the scientific reasoning, as they are a small generator. Interesting.

I would think a hair dryer on "cool" would be okay, though not sure how effective it would be. No worse than other things like vacuum cleaners. Not too often you see people using leaf blowers though.

I tend toward the manually dusting myself with brushes and/or cotton swabs with isopropyl alcohol for fan blades.

Any brushless DC motor will generate electricity with proper RPM, but in case of computer fans, there are diodes installed on the motherboard to prevent the current from flowing back so there is no worry.

This one is right, hair dryers are not built for such purposes and brushes that have soft bristles are ideal when compressed air is not an option.
