you can build a clean room 😛 ... no carpeting and the HVAC system uses hepa filtration system, the blower of the system runs 24/7 to suck what dust there is into the filters of the HVAC system.

Everytime you go into the room you must suit up, with no surface area of your body uncovered. [There is a small room built just before you go into the main clean room]

After you are suited up you must walk across a sticky floor that removes dirt from your shoes.

The systems must be continually maintained in order to keep the room clean and the room should be completely sealed with no windows and the door you enter from should be closed after entry.

Fresh air is brought in through the HVAC system that is also filtered with Hepa filters.

Basically live in a vacumm.
 
HEPA high effeciency particulate air filters?

We actually have a comp in one of these "clean rooms". It is pretty much dust free.


:-D

Pretty much dust free???

It should be completely dust free.

:-D

They have all different grades of clean rooms... some are a bit more dusty than the next grade up. Comes down to how much money you want to spend. :wink:




They do indeed :-D however a "clean" room should be free of particulate dust in most situations.

Higher grades of clean rooms usually deal with non-particulate contaminants, biological, nuclear and chemical hazards, etc

Semper Fi Carry^H^H^H^H^H Linux on :-D

There you go. If your CPU is spewing out Ebola, Radiation, or

Ammonia, then you should keep it in a "clean room".

BTW. You may want to make sure your life insurance is all paid up also. 😀

Good one! :-D
 
ooo, i got the perfect idea, get a ton of mesh and make a cube out of it, then stick ur PC in it.

One of the Lian Li's is alot like that. And to tell you the truth, I'm already underway building a case alot like you describe but it won't be a cube. I'm using extruded aluminum as the structural frame and mesh windows cover most of the surface. I'll be sure to post a pic or two when I get it done but summer will be busy and I'm not sure when I'll get around to finishing it off. My first drive bay plan didn't quite work out and that pissed me off so I'm rethinking it and may have it done up real nice by a buddy that does CAD and high quality custom metalwork. But the mesh I got is really rad! The outer layer is very strong and has large openings and it looks great. The whole thing will be so bomber, I should save it for a 4x4 rig.

Naah! Don't think so.
 
I shut the computer off once a month and take a Q-tip and dust off the fan blades, CPU heatsink, front of the hard drives, and anything else that gets dusty. You could try dust filters on the intake fans, but that would probably just make things hotter as it impeded airflow.
 
The gas is probably ethylene oxide if it is a biological clean room as EtO is a *very* toxic gas and commonly used for sterilizing objects that can't stand autoclaving, harsh oxidizing cleaners like bleach, and it is cheaper than irradiating.

But this is a computer, not a sterile research lab. I think if you tried to gas your computer with EtO you'd probably end up gassing yourself and die, and the dust would still be in there.
 
Ah, women. Sometimes they are the hardest part about getting anything done:

Me: Hmm. I think I need to dust out the computer as it's running a bit hot.
Her: Did you say dust? I think that you'd have less dust in the computer if you dusted everything around it. And it's a little-known fact that gutters full of leaves and a lawn that's a bit long also make a lot of dust.
Me: The last part's not true! Gutters aren't dusty...
Her: "The Look"- yes, *that* one!
Me: Okay, okay, I'll get to it...

I save, and use old toothbrushes for that.(don't say- ewww gross)
They are alot cheaper than compressed air, but not nearly as effective.
The toothbrush is great for fans though, small enough to get in between
the blades, but strong enough to actually clean off dust.


PS. Clean the toothbrush, and let it dry before you use it for this. You
don't want plaque spinning around on the blades. Queue the ewwww now.

LMAO 😛
 
Oh, I'm not in the least grossed-out. I use old toothbrushes to clean out all manner of things. (I have also had experiences with much more gross things than an old toothbrush that I used- a fridge that I hauled out of a cabin in 1998 that had food from 1990 in it probably tops the list :barf: ) The last thing I used them for was to clean out the crap from the light-switch cover panel as ten years' of use by the previous occupants of my house left that little opening that the switch pokes through encrusted in crud.

Compressed air has its uses, but I prefer a vacuum to compressed air as compressed air makes a mess when it blows the dust all over everywhere. Or I will hold the vac nozzle directly opposite the air nozzle so the crap that is dislodged gets immediately sucked up.

OK. Here's something i've wondered about. When i was a kid, they always said not to vacuum around the TV when it's on. I guess the
electrical fields, mess with the tubes(yes they were tube TV's back then).
Sort of like when you "degauss" a monitor. I wonder if there's any
chance of the vacuum causing static, or electrical fields that could damage
your PC's insides?


:?
 
There are chances of stuff happening when the PC is on, sure, but I never open up the case with the power switch on the PSU on, even if the computer is "off." Modern computers never actually turn completely off when they shut down- there is still juice to the motherboard and the little LEDs on the board indicate that. Blame ACPI for that one.

However, I do make sure to leave the computer plugged in as the power cable provides a nice path-to-ground in case there is some static build-up anywhere. Vacuums do tend to accumulate static around the nozzle due to the fast-moving air, but if the computer is grounded, touch the nozzle to the metal case and you'll be fine. And since the computer is off, the electrical field of the vacuum's motor won't do anything to the operation of the computer.

Probably the danger of vacuuming around an old, powered-up TV was electrical shock. The power supplies on old color TVs generated kilovolts. A plastic or rubber vacuum nozzle shouldn't be generating any electrical fields. A metal nozzle might short something, though.

Air flow from a vacuum could possibly cause static but I've never heard of this being a problem. I've used a vac near an open PC but I don't put it right onto the electronics. Keep it back a little and use it to scavenge. Some vacs can have their velocity slowed by opening a port for more control.
 
The more restrictive kind of air filtration still leaves 10 (class 10) particules larger than some microns per cubic feet. Over a looong period of time, dust could acummulate in the peecee.....
 
You know whats the best thiong about these fourm's? I love the humor you all got! :lol:
Realistically though, filters on the case are easy to make. One does have to maintain them. Its been my experance that the single best thing you can do is get your comp off the floor! Particaliarly if the the room has carpet. Terribile how much grunge a carpet holds on too..
As you sit there with it near your feet your constantly stirring it up and it gets sucked in the case, 8O gross man!
