probably your knowledge in dust layering is taken directly from your ass

Never never never clean computers/computer hardware with compressed air.
Compressed air is good for cleaning out an empty case.
Compressed air is also good for blasting dust so far into the crevices in the hardware, you short the whole thing out.
Don't clean hardware with compressed air unless you don't mind chancing your pretty computer parts suddenly becoming a chunk of useless metal and plastic.
Inb4 random "I dun it fur yerz an no problum u wrong" you can also stick your dick in an electrical socket for years and not die, doesn't mean you won't.

You can not blow the cap into the bottle. Same principle applies with dust and cracks/ crevasses in your PC. The only thing you have to worry about is moisture, so use canned air instead of an air hose.

Hey look l found the dude who talks out of his ass

Sadly, no, it's incredibly hard to find any article on it since everyone and their grandmother uses compressed air to clean their PC. That being said, it's next to impossible to find ANY method of cleaning hardware without a billion conflicting arguments.
Aside from the potential moisture cans of compressed air can generate, you're blasting the dust into/towards the hardware, which is where the potential problem lies.
However, basically anyone you ask will say "Oh no it's perfectly safe" yet here I am sitting, knowing in my personal experience I've seen many a PC bricked due to dust/moisture being blasted somewhere it wasn't supposed to go, because compressed air was "perfectly safe".
If you're very careful with it, chances are, you'll never end up ruining anything, but a lot of that will be pure luck. Don't blow air into any slots/sockets, or into any crevice like areas in the parts themselves (hard drive casings, gpu enclosures ect). People doing this is the main reason I say compressed air is bad.
The biggest thing about cleaning a computer, is not to be a tard, as long as you're careful and know what you're doing, you could even take your computer into the shower with you, and wash your down hardware down with the shower head, with 0 repercussions. Compressed air just happens to be one of the least tard friendly options for general computer cleaning, and even if you're safe, can still fuck you over.

I respectfully disagree with some of your statements, and I'll explain why.
Firstly, dust by itself is not very conductive. You can have a system entirely caked in dust, in every nook and cranny, and the system will still function assuming it doesn't reach junction temperature in any of its components. There are special circumstances where dust may have a significant enough amount of conductive or corrosive particles to damage something, but not only is this a very rare circumstance (where you likely shouldn't be breathing the air around you in the first place), in the case where dust is a cause of a short in the system, it is often times able to be resolved by simply cleaning it (i.e. with compressed air).
Keep in mind that fans, by design, blow air around and will carry a large amount of dust with it, assuming you do not have any fan filters (which many systems do not), and even with filters they will carry some dust into your system that will enter nooks and crannies whether you like it or not. Intake fans are more often than not positioned directly perpendicular to your HDDs, and if dust was capable of damaging your HDDs (which are dust/static resistant) then there would be significantly more scenarios of damaged HDDs as HDDs are very sensitive to foreign particles. A GPU can also host several fans, blowing dust directly onto some of its circuitry (there have been a handful of cases where I've had to completely remove a GPU's cooling system just to be able to clean the dust from the PCB).
Now, some cans of compressed air can carry moisture, yes, but a lot of the time these cans are specifically marked as such and a consumer should be careful in any case when investing in a can of compressed air. A wise cleaner, too, would spare some time for any moisture to escape the system before booting it just in-case, such as cleaning your case before you go to sleep.
Finally, cleaning your system and keeping it largely free of dust greatly outweighs the supposed risks of cleaning it as a system reaching junction temperature, decreasing in performance, throttling, or failing prematurely as a result of high temperatures (due to dust's insulation properties) is much more likely.
Personally, I've been using a datavac since '03, which eliminates the static and moisture problems that may be present with compressed air or a vacuum, and it's been used to clean several dozen different systems hundreds of times without issues, including my own several-thousand-dollar custom system every few months or so. Within my household of computer enthusiasts we've had plenty of issues, especially given that our systems have all been custom built by ourselves for as long as I can remember, and we've seen many more issues in the small computer store we hosted in the 90s, but none that were a result of dust shorting anything. My father spent quite some time as a system engineer at Whiteman AFB where compressed air was used to clean the servers, again without dilemma. In my brief time in the /technology/ board here on our beloved FJ, I haven't seen anybody destroy their systems via compressed air, either. A few that spilled water on their computers somehow, perhaps.
#126 - abyssinion (01/30/2015) [-]
Well, since you choose now to be respectful, I'll be brief.
-Computer fans do not blow air into/around your computer at 200mph, as compressed air usually does.
-HDDs usually have the plates and head sealed off except for a micro-filter allowing for pressure equilibrium, however the controller board of many HDDs is exposed, therefor not dust/static proof.
-Aside from potentially damaging sockets and gold plated connectors, dust usually contains a large amount of hair and various fibers, which can conduct static quite easily.
-You seem to think I said something about not cleaning your computer, ever, for fear of dust getting in things. What?
-If you ever go to socket/unsocket a working part, and suddenly it won't work, or starts having problems, with no explanation, it was probably a static cross connection.
-99.99999% who have damaged something by blasting compressed air all over the place, have no idea what caused it, as compressed air is so perfectly safe to just point and shoot in there, so of course you don't hear about it.
-The servers would be a completely different situation than home PC maintenance.
Since computer parts are quite sensitive, blasting them with a high psi gale force explosion of air can obviously have negative effects. It's like pressure washing your junk and hoping for the best.
You're sure nothing can ever go wrong though, so here's hoping you never had and never will have any mysteriously uncooperative computer hardware.
#154 - kober (01/30/2015) [-]
A modern datavac is rated at 70 CFM or less, and a compressed air can likely produces less. You can obtain fans that produce as much as 240 CFM www.newegg.com/Product/Product.aspx?Item=N82E16835213001 that I know of off the top of my head, and I've owned them before. In the very same system I had some old Maxtor HDDs with the exposed controller and all, constantly barraged by dust from the deltas, which were also flinging dust particles all over the remainder of my case like small projectiles. I'd imagine if such air pressure were bad for the parts, they'd have a reputation as such... Of-course, HDDs aren't static/dust-proof, they are static/dust-resistant, like I stated. At one point I couldn't see the PCB of my motherboard in the system they were in, as everything had a nice layer of dust over it. Poor maintenance on my part, admittedly, but I was young and didn't really care, and the system ran just fine. Dust's conductivity is largely dependent on what's in it... carbon and metallic particles are conductive, for example, whereas glass fiber and polymers are not. Hair, cotton, etc. that make up dust the majority of the time are not conductive unless exposed to a spark, where they may then carbonize. If they were as conductive as you seem to believe (which, all the more power to you for what you wish to believe), then systems would fail far more commonly as just about every common system is subject to dust. I for one don't have many sparks that occur in my system and I doubt many do, so carbonized dust is unlikely. If a part stops working after I replace it, it's probably because I was working on my computer on the floor, wearing socks, didn't bother to ground myself, and damaged it by my own collected static electricity, which is another far more likely dilemma. It's also not very difficult to turn off your computer, clean it, and then when it doesn't turn on use your deductive reasoning skills to realize that the process of cleaning it was what damaged it; the world isn't really full of completely brain-dead people, and there are a lot of computer enthusiasts that take time every month or so to clean their system that would be able to easily troubleshoot what caused their issue. Servers aren't that much different from any normal system outside of the specifications of the system, although they typically have fairly robust dust filters and all so they're largely irrelevant in the case of dust.
I'm not entirely sure what kind of compressed air you've used, but for the most part compressed air tends to leave a thin layer of dust because they're not, as you'd say, pressure washers, they're designed to remove enough dust to maintain optimal temperatures. They're just enough to clean up the majority of the dust, not detail your system until it shines. Most of the time I still go through with a microfiber cloth and wipe off any leftover anywhere significant. Is compressed air a perfect technology? No, and I never said it was. I'm stating that to entirely disregard the most effective and common practice of PC maintenance because of something that happens in a lightning strike's chance is just silly. If it's what you wish to do, by all means do it, but you shouldn't (in my opinion) spread it like you're one of those parents who didn't vaccinate their child.
#159 - abyssinion (01/30/2015) [-]
"You're sure nothing can ever go wrong though, so here's hoping you never had and never will have any mysteriously uncooperative computer hardware."
That was my attempt at ending it since you're just going to keep quoting what is most likely google searches.
You're rants are also are containing more and more information that doesn't pertain to anything I've said. "unless exposed to a spark, where they may then carbonize" That's called an electrical fire, pretty sure I didn't mention anything about minute electrical fires. So before you start quoting more irrelevant wiki information and arguing points I never made "Is compressed air a perfect technology? No, and I never said it was." (I never said you didn't) how about we go back to me saying do whatever you want and good luck.
Please dear god forgive me, for being foolish enough for saying something that can damage your system, can damage your system. Unfortunately a lot of the things I learned about computers was from my father, who's been building, programming and working with computers since they operated off punch cards, unfortunately he doesn't have the experience of blowing out servers for a few years. And in the hundreds of thousands of computers we rebuilt and refurbished to be donated to schools in Africa and other 3rd world countries, while he ran a Computers for Schools shop, we saw a lot of things go wrong, but I guess not as many things as a few geekoids in an apartment. I bow to your overwhelming experience, I was obviously wrong.
#176 - kober (01/30/2015) [-]
That statement is an incorrect attempt at simplifying what I've said; I never made the implication that nothing can go wrong. You can call it an attempt at ending it if you wish, but if that were the case, everything I've stated thus far has gone over your head. If you wish to disregard actual research and procure your own statistics and facts with little to no basis be my guest; after all, that's what Andrew Wakefield did and people believed him, too.
Allow me to repeat, perhaps more simply for your sake: dust is largely non-conductive and will remain so (therefore there will not be any threat of shorting due to dust in the mass majority of systems) unless subject to a spark, whereas the process of carbonization (the conversion of an organic substance, such as the hair/skin/etc. in dust, into carbon or a carbon-containing residue) will make the dust conductive and therefore capable of shorting/damaging a system. Does this happen often? Fortunately not. This is the very simplified science of why your belief, while in good heart, is not quite true, which you valiantly ignored, like most of my points. I guess dust being conductive or not has nothing to do with your statement about dust conductivity...?
I didn't realize this was a "my dad could beat up your dad"-esque debate. Paired with all of the other attempts at insults and sarcasm written in poor taste, I'm actually rather amused. I applaud the humor.
#196 - abyssinion (01/30/2015) [-]
Well, I'm sure my dad could beat up your dad.
The problem here has been, you're trying waaaay to hard to sound smart, and most of your points have been rather off base because of that. You haven't actually argued the points I've made really, you've just tried to cram as much general information into the subject as you can.
You can repeat things you've heard or looked up, great job, A+.
We've been arguing different things this whole time because you're too busy showing off how many loosely related facts you can cram into one large painful to read wall of text.
For instance I said compressed air, and in you come with your datavac, which as the name might suggest, is a electric vacuum, not compressed air.
You see my concern yet?
#212 - abyssinion (01/30/2015) [-]
Since I have to be off for a while, I'll try to finish up here.
As I said, I was talking about compressed air, not something like a datavac, I in fact said in a reply before you started your wiki splicing that I'd head of some hand held vacuums made for cleaning electronics, and they'd be the best bet.
What I was always referring to was compressed air, generally the kind sold in cans (as an actual air compressor is usually just a bad idea). The air from those cans you're supposed to use to clean electronics comes out at around 70psi at standard room temperature, which is a fair bit (when I mentioned the psi of compressed air you went off about the cubic feet/m that general fans push as if it had anything to do with the PSI of a compressed air canister). Now if you're blasting your mobo with 70psi of compressed air, you don't think it could possibly be a clusterfuck of stuff getting thrown everywhere? Potentially just jammed DEEPER into the components?
Now as far as the conductivity of dust (which I never mentioned conductivity) you seemed to think I meant some dust here and there was as good as throwing a handful of copper wire into your psu. Things like hair and certain fabrics are great and collecting a static charge (which is different than current electricity[conductivity] btw, but thanks for the grade 7 lecture on the chemical reaction of ignition), especially when surrounded by different electrical components, that static is looking for a place to discharge, where's a great place to discharge? Why into those gold plated connectors on your gpu for instance, now USUALLY those discharges aren't a problem in the slightest, but it can easily get to the point where the discharge (which can happen even while computer is off) can damage the hardware.
Your points never went over my head, your points were just never relevant.
#211 - kober (01/30/2015) [-]
You're misinterpreting the purpose of the discussion; sounding smart isn't, nor ever was intended, I've merely articulated my points so that you can better gather a grasp on them as you appear to have had difficulty doing. The purpose of my input is to share knowledge I've gathered so as to make you a more knowledgeable person, not to attack the misinformation you, oddly enough, hold so dearly.
You seem to confuse specific reasons why your points are invalid as "general information." As a matter of a fact, I even spent extra care to follow the same order as your counter arguments, but perhaps that, like much of my input, was unable to be processed by yourself.
A datavac is an electric duster (not a vacuum, mind you), the same way a can of compressed air is a gas duster. They both achieve the same thing: blowing air with enough pressure to blow off a sufficient amount of dust. A datavac is more easily referenced because you can gather its specifications more readily than you can a can of compressed air, i.e. the CFM air travels from it.
You seem both confused and overwhelmed. I would be concerned with that fact, too.
#226 - kober (01/30/2015) [-]
It's late and I've grown bored of this cycle that has and will ultimately lead nowhere, and inevitably hasn't lead to you being any better informed of maintaining your system as I had hoped. A shame, really, since as a computer enthusiast I only wish the best for people's understanding of their computers. You're painfully ignorant and have ignored everything I've stated; the only good to have come from this is perhaps others hopefully not falling for the same. I wish you the best of luck: if computers ever start dropping like flies when people use compressed air or any statistics would ever suggest so whatsoever, perhaps then people will concede in your argument.
