Paranoid question for a rookie builder (Air Can)

[BunnyKraken]

Hi,

 

This might sound neurotic/paranoid and overall stupid question but I have to ask because I don't know. So I built my PC with some issues, got it powered on and into bios. 

When I turned it off I realized, I powered it up on a old wool carpet, and with the bottom fan on. I hope this isn't an issue, just some dust/microfibers might have gotten inside ?

 

So I used a can of air, and sprayed it underneath at the PSU fan, BUT the canister was upside down and it sprayed some white air (aerosol probably) into the PSU. So my questions are

 

1.Was it harmful to use the air canister upside down(it said behind the can not to use upside down) and spray it into the PSU. And should I leave it turned off now for some time, can the aerosol be harmful for the components inside the PSU, and could it harm it ?

2.I guess powering the PC on the wool carpet just gathered dust, and nothing more inside the case ?

Yes, don't do that again. Also, don't shake the can

Basically you can compare it to spraying liquid nitrogen on your components so let it rets for a day or 2 and don't do it again. If it wasn't on and unplugged no harm should have been done.

These cans are filled with refrigerant. Refrigerants tend to have an extremely low boiling point, so once the liquid gets out, it should evaporate almost instantly. That said, I would exercise caution and leave it unplugged for a day or two.

 

In the future, spray it upright and in bursts.

There is a liquid inside which is a gas at usual air pressure but it is compressed in the can.
If a liquid becomes a gas, energy is used, so it becomes cold. So if you put the liquid on PC parts and it becomes gas there, the PC parts become really cold and that might harm something.

It's fine it won't hurt your computer. It evaporates almost immediately. You don't have to leave it for a day or two. It's usually just C02.

Thanks, to all for the answers. Didn't know it could be this harmful.

Im not sure how much actually went in to the PSU. I realized immediately after one burst that it's not suppose to be used upside down, because of the white spray.

 

The computer was turned off about 5minutes prior to this, and now I haven't turned it on in 6hours, so I will not ruin anything  

So would it be okey now to turn it back on and install windows, or wait the recommended 1-2 days.

 

Out of curiosity what could happen, and can something still happen later on when the PSU gets warm in the next weeks?
