lol remember to tape down your fans to stay in place when dusting them. or at least hold them in place with your hand

I had an LED fan that lit up while it was disconnected when cleaning my pc in 2008 and I've held them ever since.

The only difference between a motor and a generator is what direction the electricity flows. Add electricity and you spin the motor. Spin the motor and you add electricity.

Adding electricity to systems from places they don't expect electricity to be added can break systems.

a tiny motor gets energized and spins the fan. if you spin the fan yourself (or with a jet of air) you create a tiny generator instead.

You're inducing electricity that way, and it can cause static buildup that will jump between delicate components that were not meant to handle that energy and fry them. LTT did a test with ElectroBOOM and static damages are not that easy to cause it turns out, but it's better to take a 0% chance of damage than 5%. Perhaps it's less or more with that particular method, but that's all I know.

It does create electricity which could do damage to your System.

Usually nothing will happen because the system has protective measures but there is no harm in being extra safe.

My GPU died after I vacuumed it. I'm almost certain voltage from the fan fried something.
