Condensed Air Can, questions with usage

[Azureworlds]

Hi everyone, I was cleaning my computer yesterday and I had a few questions about using condensed air to clean your computer. While I was spraying back fan from the outside, I guess my angle was more than 40 degrees and the white foam sprayed all over the outside of the fan, I didn't turn off my computer so I guess the fan caught most of the foam as it was spinning if any got into the computer. This was a brand new can of condensed air so i guess the angle at which i used it mattered a lot more since the foam was near the top of the canister. Anyways, my computer is fine but I was wondering what the possible outcome would be if the liquid had gotten onto any of the components. I didn't realize the solution used in the can was flammable as there were no warning labels on the can about it. The only thing that it said was to not use it in a compact area as the flames can ignite and catch fire. But it was in small print near the product description.

I also spray some of the air while the can was vertical on the graphics card and some at the heatsink while my computer was running. Looking back I realize I was being stupid for not turning off my computer first.

THat's not foam. That's liquefied gasses and it boils off fast. It will suck the heat out of anything it touches, too. If just a bit got out then you should be fine. If you throughly douse things with the liquid you could damage things with thermal shock. The gasses used are supposed to be non flammable.

Take this as a learning experience, it's best to shut off the system when cleaning it out.

PS, using a can of air upside down to quickly cool parts is a handy tool for diagnosing parts that only start erroring out when they get hot.
