Dusting inside P.C. , freezing temps

Hi guys,

I can't check back until tomorrow so thanks in advance for any answers.
I live in Chicago and need to dust out the inside of my P.C. It's in the low 30's out and I usually take it outside and blast it out with a shop-vac blowing in reverse (holding the fans so then don't spin too fast). I would let it warm up with power off before using again but will bringing it to the driveway in freezing temp going from typical indoor (P.C. off temps.) be harmful?

 

I don't see how spending a few minutes outside would affect anything, now if it was -30 that could be a different story. Only thing to worry about is condensation and leaving the machine off for a few hours is the best thing you can do.

 

From my experience, it is much easier to overheat your pc than to overcool it.

 

Thanks guys, I'm gonna give it a go.
