PC Dust buildup

R

Rob

We have serious dust problems in our area. There's never a time when I can
go beyond 2 or 3 weeks max. without cleaning all the computers in the house.
I built the computers we use and 1 has 5 cooling fans, 1 has 6 cooling fans
and mine has 8. So there is a huge amount of air movement in these
computers. Hence, dust buildup is very frequent. In my opinion dust is rated
as one of the top enemies of technology. It is a great friend to heat and
the heat is a great enemey to computers.

I've tried every method I can imagine to find the best solution to clean
them out. Canned air....try using around 6 cans for 3 computers every 2 or 3
weeks....way expensive. So I bought a 2 or 3 gallon air tank at WalMart for
around $17. It takes a quarter to fill it and with some serious brushing
with a good auto parts brush, the tank will do 2 computers. There has never
been an issue with moisture using this method.

But.....I've finally found the best solution I believe possible for cleaning
the dust and dirt out. I remove both side panels, take it outside on the
workbench or picnic table and blow it out with my leaf blower. Go ahead and
laugh, everyone that I've told gets a good laugh about it.....but believe me
it works beautifully.

Always check to make sure you don't have any loose components or such before
you start. I have my wife hold the cooling fan blades with the handle of my
cleaning brush to prevent them from spinning.....I'm afraid they may spin so
fast it could create possible damage. After cleaning the area around the fan
blade she is holding, she moves her brush handle on to the next cooling fan,
etc.

You have zero moisture to worry about. You have zero brushing to do and
every spec of dust and dirt is removed. Even from those areas like inside
the cd trays, etc. that you had a hard time getting to before.

YES.....let me be perfectly clear, YOU MUST USE CAUTION! Make no mistake
about it, if you're not careful you can do some very serious damage. It's
much like going to the car wash and using a very high pressure sprayer, any
knucklehead knows you don't put the tip of the wand right up to the car
surface....doh...you'll be removing paint, not the dirt and mud. Just
remember you have total control over the leaf blower and you don't have to
stick it right against the graphics card or power supply to remove the
debris. And you don't have to rev it up like you're getting ready to race,
just take your time and get the feel of it and you'll quickly realize how
and where to use that trigger finger. Oh, with this method it takes longer
to remove and replace the sides than the actual cleaning job.

Take care and good luck, Rob.

Unless you live in a desert area, you've got some serious problems. If the
dust is that bad, it's also a medical threat. Heck, you would have to
change the filters on the House AC unit every couple weeks too.

I call those POOF cans since they make your money go POOF in no time at
all. A cheap air compressor, from walmart or home-depot, will more that do
the job properly, and you can use it to blow up balloons for parties :)

Now that's the funniest thing I've seen today.

One bit of advice - never use a BRUSH to clean computer parts.

Ahhhhhh......wow, you are so right. I never even thought about all the
potential static electricity all the brushing creates.

Great point and thank you very much for that post. That's the great part
about these forums, you can learn something new no matter what level of
experience you have.

Take care, Rob.

Piece of air conditioner foam filter taped over the fan hole! Works great.

While I own two static bands, I've never seen anyone else that owns even
one, not in 40 years. The only people I know that own them are people that
have been through ESD training, and not many residential users have :)

We can still try - I sell PC components on ebay, and all ship with a
disposable strap and a note saying the DOA warranty is void if the buyer
fails to use it.

I take them outside and use the shop-vac on blow - same idea, works
great, but I wear an anti-static strap and hold the end of the nozzle
just in case.

I deliberately spin the fans as fast as possible as it gets the crud off
the underside of the blades without using a brush. I've been doing it
for years, never had a problem with fan damage.

Well, based on everything that was said, I can see there is much a
difference of opinions on this issue.

I do feel that I will try Mr. Michael Solomon's idea of blowing out the case
from the product at Cyberguys.

the only difference of opinion is really if static is a threat or not and
how it's introduced during cleaning. In all cases, using a plastic hose
will generate static unless the hose is part of a grounded system with a
conductive plastic designed to discharge static.

Newbie, be sure to make note of and pay heed to the issue of static
electricity as mentioned in this thread. Cyberguys also sells antistatic
wrist straps and they are relatively inexpensive. They sell both cord and
cordless. The corded type uses a ground wire that must be attached to
something metal, the cordless type must be put on about 15 minutes prior to
doing any work in order for it to properly discharge static electricity:

work in order for it to properly discharge static electricity:

I read the description of it on their site, the only place I would use
something like that is sitting at a bench, not leaving the bench, and in a
room that is designed to be static free - in other words, I would not
trust it to protect anyone in a home/soho setting.

Leythos

Good point. Unfortunately, there's not always something around to which
you can attach the ground wire but I agree, the corded type is better.

If you leave the computer plugged into the wall outlet, with a proper
grounded plug/outlet, the case/PSU should be grounded - touching it will
discharge the static.

There is no mention of the resistance used - if this unit doesn't have a
resister then you could be setting yourself up for electrocution. As I
recall, the resister should be on the order of 10meg/ohms or something
like that - low enough to discharge the static, high enough to keep you
from being killed if you contact 120VAC power.

Yes it would, I thought about that after I pressed send. I was thinking in
terms of most home offices having mostly composite materials which can make
finding a proper ground problematic. Personally, I tend to prefer not to
leave the computer plugged in when opening the system. That said, the case
being metal, could you not attach ground wire to the part of the case you
remove to open it?

You can leave the computer plugged into the wall, turn off the power
switch on the PSU itself (there is almost always a switch on the PSU on
quality units) or disconnect the power connections from the MB if you
want, but the safest method is to just allow the electrical ground
provided by the PSU to the case, to remain in place so that you don't have
to purchase/do anything, it's already grounded.

In almost 30 years of working with electronics I've never fried anything
with static, and with computers being left connected to the power (with
power off) I've never damaged one yet.

Thanks Leythos and thank you for your contributions to this thread, most
enlightening.

Thank you, I just like to give back as I've learned a lot from Usenet over
the last 20 years.

I got an email about using one of those little computer vac's and blower
units to clean systems, here is what I responded - in case anyone is
interested.

The question was about this device:
Can you recommend the best antistatic products and steps I should use when
I use this product below?

http://www.cyberguys.com/templates/searchdetail.asp?T1=114+0570&dept=&search=&child


Here is my reply:

There isn't enough information available for the product you selected for
me to know if the unit it going to generate static. What I can see is that
it uses a standard 2 prong electrical cord, which means that it does not
have the "earth ground" prong (the third one), so that also means that it
might not properly discharge any static if it were to create it.

When it comes to static and cleaning, I use a poof-can or a real air
compressor - the cans are metal and if I'm grounded I know that the can is
too (since it conducts through my body). With the compressor, it has a
metal fitting at the end of the hose, so the same applies, if I'm grounded
so is the air exiting the nozzle.

When it comes to cleaning a computer, via air (inside or out) or via rag
(only on the outside of the case), I just leave the electrical cord
connected, turn the power off at the PSU and on the front - remember, the
new P4 units almost always have power to the motherboard unless you can
turn off the power on the PSU (the switch I was talking about)

If you look at this power supply, just below the AV power connector there
is a small black flip-switch, this would turn off the power and stop the
supply to the motherboard:
http://images.tigerdirect.com/skuimages/large/P456-4000-main.jpg at the
same time, it leaves the computer properly grounded so you can use it as a
good static discharge point (the case).

When I hand ANYONE an electronic part, even if they have an ESD strap, I
always touch them with my finger first - this puts us at the same charge
level, so the part I'm handing them doesn't get zapped.

When I put a new motherboard in a computer, I take the box (unopened) to
the computer, touch the case frequently while opening the box and the ESD
bag containing the motherboard, then only handle the motherboard directly
once I've touched the case while also holding the ESD bag right before
removing the motherboard. I touch the case frequently while working with
the motherboard in order to maintain a static free install.
