If your compressor doesn’t have a dehumidifier you risk blasting a bit of water, too, and with the pressure/velocity it can reach places that won’t dry out quickly.
I wouldn’t worry too much about shorting as there should be diodes all over the mobo to prevent current from feeding where it shouldn’t but you could overdrive the fan and wear it out faster. A can of duster can do this too so just hold one of the blades and blow around it as you move your hand to cover the whole thing.
As every electric motor is also a generator, yes.
Just put something between the blades before you blow it out.
Those cans suck ass, at least for my experience. As the content cools of through expansion, you have about 20secs of charge before you have to wait for the can to get warm again :-/ but results may vary
I got a plugin one instead of battery-powered. If I’m dusting a computer I’m going to be near a power outlet anyway so it seemed pointless to make it wireless. It’s was both cheap and quite powerful, I use it for blasting dust out from under furniture and other such handy tasks as well.
The cans work fine but you’re only supposed to use it in short bursts not holding down the nozzle and going to town. I typically but a multipack and alternate between two if I need to use them for an extended period. Also keep in mind that the straw really limits the blowing force so use it only when you need to.
Compressed air is good but there are a few things to consider.
Be aware that if you are using a tool shop compressor it may be too powerful and can tear components from the pcb.
Do it outside and wear a dust mask or stand down wind and try not to breath the dust.
Don’t allow the fans to spin on the compressed air, you may reverse the charge and short components.

I never thought about the fan spinning issue, is it still a problem if I’m just using a can of compressed air?
The fan spinning and causing a short out is a myth. It’s been tested and doesn’t generate enough electricity.
Any chance you’ve got a source for that test?
Yes, but all you need to do is stop the fan from spinning by holding it in place. This will be better for cleaning anyway.
I allows thought it isn’t allowed to spin into the “wrong” direction, so I always put a pencil in it to stop it from moving. No idea if it’s a myth.

I’m a big… proponent… of handheld rechargeable air blowers after getting one from Wolfbox.
I always felt like I was risking frostbite with the cans.
I tried one once, it was weak and useless.

I have a similar plug in blower that works great. Can’t believe I never thought of using it to clean under furniture, thanks!

Thats something i didnt try, thanks for the input. But since i got myself a proper air compressor, i dont use these cans anymore
But the dust and hair feels so good deep down in my lungs.
