Are these safe to use in inner PC components? Someone got me one, but it seems to be slightly humid/watery-like at the center of the sprayed area.

Thanks in advance

I use cans of compressed air all the time.

What looks like moisture is actually the result of the release of compression on the nitrogen coming from the can.

The process is called adiabatic cooling.

A gas under pressure will drop in temperature as a result of pressure being released.

This makes the can frosty, and makes the nitrogen coming out appear to be like water vapor.

But it's perfectly safe for electronics.

Unrelated - What could be causing my GPU to not increase clock speeds when running a game?

Only thing I have done is run DayZ, which due to its poor optimization has the following launch options

-nosplash -noPause -cpuCount=4 -maxMem =3981 -exThreads=4 -maxVram=3072 -winxp

Probably just DayZ itself, it isn't a finished product.

But I will note that it isn't harmful for electronics, but it can be harmful for humans. The nitrogen displaces oxygen in your lungs and you can very easily suffocate if you try to huff it.

Edit- I say this because it recently came up in preclass conversation before one of the courses I lecture.

One of my old acquaintances from high school got hooked on "huffing duster"... she was attractive and rather intelligent... now as I understand it, she is essentially a walking vegetable.
