| 1446982 | 2018-03-04 22:32:00 | So how do you clean your PC? either an ESD safe vacuum cleaner (we have one) . But with that you still have to get in there with a paint brush to loosen all the dust I hold the vac nozzle away from the board , lossen all the dust with a paintbrush . I guess if you put the vac nozzle right next to the board , that would be more of a risk or just compressed air, via a home air compressor if its really really dusty. Sometimes there is no other way to get all the dust out. |

| 1446983 | 2018-03-06 00:42:00 | Here you go, a low or no cost compressed air can, easy as peasy DIY: Procure or buy a tyre valve. I bought a rubber valve stem, hardest and longest part of the job is removing the rubber down to clean brass. Measure diameter of stem. Take one empty fly spray can. Make sure it is empty. Flush through with compressed air to make sure no hydrocarbons present. Drill hole in can to size of stem, slightly under size, and taper ream hole if needed to make stem a tight fit. **tape down the valve lever at the top of the can to open it to atmosphere, otherwise the air will expand when the can is heated and maybe blow out the hard solder** Silver solder with gas torch (Easi-Flow hard solder) stem to can. Pump up with compressed air ........done Notes: These cans according to manufacturers data have a burst pressure of > 2Mpa.....300psi. The higher the pressure the longer the air will last, my 12v tyre pump only goes to 120 psi. 150 or 200 psi would be better. For cleaning a computer you may have to re charge a few times. :clap |

| 1446984 | 2018-03-06 05:58:00 | a can of compressed air at 200psi is not going to last long. "can of air" is refrigeration gas. so its liquid in the can, so it holds a lot of "air" for its size. edit: if using compressed air, make sure its fairly dry. draining the water out of the filter/tank still means the air is 100% saturated with moisture. you need a drier in the system. |

| 1446985 | 2018-03-07 18:05:00 | I am thinking of a two pronged approach. I like the idea of using the compressed air cans, as they may be as Tweak says above - refrigeration gas, that is why the air is cold. But a can only seems to do one clean. So I may buy a small compressor and use that to do the case and grilles and non critical parts, and then finish off with a can to do the CPU fan and the motherboard. |

| 1446986 | 2018-03-07 19:07:00 | I am sure sucking the dust away with a vacuum cleaner is infinitely superior to blowing dust all over the place and it being forced into nooks and crannies, even into fan bearings, or back into the room to be drawn in again by the fans :clap When I was in bearing research and machine tools and precision bearings of all sorts, compressed air was an absolute no no. Ok when you are machining and blowing off suds and swarf, if done prudently taking care with your eyes, common workshop practice. But I'd never happily use it on a computer. Still if you can afford the rip off price then go ahead, your decision. |

I use a ryobi cordless compressor/ inflator myself - for all of it. If there's any contaminants in the air I can't tell - I spayed a piece of clean white paper and can detect no residue. The comment about refrigeration gas prompted me to google it and yep it's not air in those cans en.wikipedia.org One little picky point I can't let go, the "air" in the can is not cold - it's at the same ambient temperature as everything around it. When it expands it absorbs heat energy from everything it touches and that has a cooling effect, but the "air" itself is not cold. |
