Default High pressure air cans safe?

I've seen these cans of pressurized air they sell at Frys. Sounds like a good idea, get the dust out of those deep fins. But are they safe? I figure high pressure air could also do some damage to delicate parts of the motherboard.

You mean one of these?

Yeah, they're fine. They're actually a necessity for cleaning your rig.

Just don't spray it upside down, or tilted too much.

You won't hurt any components of the motherboard with it. They aren't powerful enough. But as said, don't tilt them more than 45 degrees or spray upside down, or shake it, because it will shoot out really really cold liquid that might crack components. It also causes instant frost bite, so don't spray it on yourself.

But yeah, otherwise, it's fine.

They don't have high enough pressure to do damage. I use air compressors on PC's to clean them out before which has more pressure than canned air.

Definitely don't tilt it upside or at too much of an angle otherwise they're perfectly fine.

Can you use them to blow the dust off the foam filters on the case? Those are the biggest pain, I take them off and rinse them in water, then leave them in the sun a couple of hours to dry. Then in a month they are all full of dust again.

I could see rippings holes in those pieces of foam with compressed air, though.
