Title: Dust Bunnies!
Post by: GigaBuist on November 01, 2011, 10:49:15 PM
Thought some of you might get a kick out of this.  The last two days have been spent breaking down point of sale computers at our business, cleaning them out, and putting them up for storage.

This is what a PC looks like after spending 6 months in a greenhouse... and most of that time it was off and not sucking in any air:

Takes about 4-5 minutes with an air compressor to blow it all out.

That ain't bad.  You should see one that's been in an autobody shop.  Or a barn.

Or a Kindergarten classroom. Looked like it had been tied behind a pickup truck and dragged through the desert for a couple of hours.

Need to see the insides of some of the computers over here in Kuwait and Iraq.

At least it isn't full of snake skins and several skeletons/carcases!

Working computer repair I think the most interesting I'd seen is a computer that had been used as a bong.  Gave the entire store a rather distinct odor.

'Why isn't it working any more man?'

Damn.  Good to know people have seen 'em worse and still functioning.  Coming from a clean office environment you'd get some dust buildup in them over years, but nothing like that.  Stuff that had to be up and running all the time went into a proper data center with air filtration systems in place so you'd never see crap like that happen.

Guess I'm a little too paranoid about a few ounces of dust. :)

You don't have to worry about the dust too much, as long as they get blown out from time to time.

Being in a greenhouse you want to make sure all extra slot covers are in place. A mouse hiking a leg on a pc card make things stop real quick.

Bugs might be the one you have to watch for the most. I've seen ants and roaches just kill boards in HVAC and other electronics.

you can get cases with filters. for them to work right you need positive air pressure in the case though. can get loud, or expensive. if your exhaust fans speed up as the computer gets hotter. [tinfoil]

or if a new case is out of the question, you can add filters. but most of the time, there to hard to get to to clean. :facepalm:

if it's worth the time, look here for ideas. (http://www.frozencpu.com/products/2623/ffi-05/120mm_Washable_Fan_Filter.html?tl=g47c223s876#blank) [popcorn]

Why not completely seal the case and liquid-cool (http://computer.howstuffworks.com/liquid-cooled-pc.htm) it?

Because it's a PITA and it's expensive. Hard to do when you got a bunch of computers, such as in a retail environment.

Why have I never done a refrigerated system? Money is not an problem with some groups.

I have a new winter project.

I work maintenance at a knitting mill. We don't get dust bunnies. We get dust badgers and dust rhinoceros's. The machinery has to be cleaned every shift, we use an air compressor and the oily lint is usually a couple inches deep. Even with screens covering them, cooling fans load up pretty quick if they aren't cleared.

Funny you mention that.  About two years ago, our 1 year old AC stopped working. I traced the problem to a solenoid switch on the outdoor unit.  There were several dead silverfish around and in it.  I called the company that installed it and had them come out.  They guy said the cover for the switch was available, but they only put it on if there's a problem like this.  I couldn't help but wonder why they wouldn't put it on as a matter of process since it didn't cause any problems and seemed to fix a big one.

Last summer, the switched failed completely.  I could manually actuate it, but it wouldn't automatically switch.  The guy came out swore that switch almost never failed.  He did his "tests" and agreed with me the switch had failed.  ;/
