Using duster to clean inside computer

post #1 of 7
Thread Starter 
I wasn't sure where post this, since there isn't a "homebuilding/maintenance thread" but I have an i7 intel rig so:

Is the general rule to use duster to clean the inside of the computer, to do so when the computer is powered "OFF" and unplugged?

Could using a can of compressed air of "duster" while the computer is on cause damage?

Please let me know, thanks.

If you're going to use canned air don't use the straw. Focuses to much air on a single spot and can blow the dust even deeper into a component.

Yes, only dust when the PC is powered off and unplugged. Using canned air duster while the PC is on is a no no, if you tilt the bottle past a certain degree it will spray liquid out- never good for powered on components.

If the computer if OFF is that enough?

Does the computer need to be unplugged ALSO, and if so, why?

Honestly I don't have a reason, just when dealing with a couple thousand in components, the small act of unplugging a cable is good reassurance that the PC will power back up when i am done tinkering with it.

Yep, I agree with turning it off and unplugging it. I'm not actually sure if the duster liquid is conductive or not, but I don't really want to find out either. Even when the computer is plugged in but powered off, some power goes to the motherboard, meaning there is still potential for trouble (if in fact it is conductive at all).

At the least, it's important to have the computer off. Otherwise, you'll be blowing compressed air while the fans are trying to run. You could end up with some interesting problems I imagine if you sprayed really fast air the wrong direction at a moving fan (burn up the motor? not really sure..)

I would agree always turn off your computer when cleaning it out. Also I as a rule never open the case of my computer without wearing a grounding strap but that is just me seen way to many electronic components destroyed buy static electricity.
