Earlier I reported messages in my kernel log that indicated a possible
failing SATA HDD. The messages described a repeated slowing of the SATA
HDD transfer speed from 6 Gb/sec to 3 Gb/sec and then to 1.5 GB/sec.

Some assholes suggested using smartctl (smartmontools) to diagnose the
problem but any idiot can see that the issue is NOT the HDD but rather the
SATA controller.

Thus, at first I thought that my motherboard was failing.

However, upon close inspection, I noticed huge amounts of fine dust
particles that were clogging the cooling vanes of the CPU heat sink.
Using a brush I scrubbed away all the fine dust and ever since I have
not had a recurrence of the problem.

Apparently, the issue was caused by excessive heating of the CPU.

Smartctl! Ha, ha, ha, ha, ha! What a bunch of stupefied assholes!

It's no wonder that they are all distro lackeys.

Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha!

That's number one in ruining my drives and generally sensitive
electronic stuff. Here in this area they're almost always pollen.

Very special air filters can remove them from your rooms, but those
filters are expensive and should be replaced every month or so.

Pollen are strange things. They're alive, you know. So they change
chemically into corrosive stuff that get deposited on vulnerable
surfaces and gradually eats them away.

This is definitely a physics problem.

I have a very powerful fan blowing air through those cooling vanes
and they will eventually become totally clogged. Considering the
strong airflow, Why is this happening?

I posted this question to sci.physics.

My theory, which I believe to correct, is that the stationary
boundary layer that always develops when flowing air contacts
a surface is responsible. The dust particles can easily settle
in the stagnant layer and then more will eventually settle on
the layer created above, etc.

Other posters claimed that static electrical charge is responsible,
which I find to be nonsense as the cooling vanes are grounded.

I don't remember that post. In sci.physics you must be under an alias

You have no idea how long that kill file list is. God forbid I lose it

The two views you mentioned seem to me could be one and the same thing.

How so?

If a metallic structure is grounded, it cannot develop a static
charge.

But, in flowing air, the stagnant boundary layer is always present.

That's also the reason that dust cannot be removed by a blast of
compressed air. The only way to remove it is through mechanical
action via a brush.

We need to get some aerodynamicists involved in this issue.

In what you described, friction with air is continuous, so it maintains
some degree of non-zero charge formed on the surface even if the device
is grounded. Charge is constantly moving of course, because of the
grounding, but the net charge at a spot on the surface won't be zero
where friction is taking place. This attracts particles of net opposite
charge and eventually you have a lot of dust on your mesh.

Even in the absence of a fan blowing air at it, you see dust forming
eventually because even the temperature difference between the metal
mesh and air causes tiny air flow around it (convection) which in turn
begins a tiny friction that's continuous, and as cooler air replaces the
warmed one around the mesh (or vice versa depending on which has higher
temperature) more and more particles come in contact with the mesh.

The charge on a mesh formed by continuous friction with air is more
likely positive if the mesh is metal or glass, and likely negative if
the mesh is plastic or rubber. So depending on what the mesh is made
from, you can use air filter devices that can give negative or positive
charge to the particles in your room, and choose one to create same sign
charges on the particles that you have on your mesh, thus preventing the
dust from getting attached to the mesh.

No.

Trucks can develop static charges when moving down the highway
at high speed but they used to install chains that dragged on the
ground to dissipate the charge. Chains are no longer used because
truck tires are made to be conductive and will dissipate any
charge.

A grounded heat sink cannot develop a static charge.

Here is a post on reddit which describes the boundary layer
effects:

https://www.reddit.com/r/askscience/comments/3hcd6s/how_does_a_constantlyrunning_fan_collect_dust/

This is an excellent description and one of the best that I
have seen.

The boundary layer can be very significant. It's why they
add "dimples" to golf balls.

It's hard to believe. The dust didn't came during the night. And when
the heat is too important, the HDD doesn't slow down, the CPU shuts
down. Not the same symptom, not the same story, I don't believe that.

Listen, you imbecilic idiot.

I build my own computers and I do not follow conventional designs.

My motherboard is not housed in a box, but rather it is completely
open on a small table. To ensure adequate cooling, I place a large
fan next to the table to pass high volumes of air across both the
CPU cooler and the HDDs.

At some time in the past (I don't recall exactly) the fan attached
to the CPU cooler stopped working. But that did not matter because
the high air flow from my external fan could easily provide the
cooling.

Now, high volumes of air passed over a surface will, eventually,
produce lots of accumulated dust. I had just neglected to clean
the system.

In the future, do not EVER attempt to overturn my statements
with your idiotic, but only to YOU perceptive, rebuttals.

Fuck you, cretin.

Look up my brilliant posts on sci.physics which PRECEDE that Reddit
post.

I was conversing with a sci.physics regular known as "jimp" (a.k.a Jim
Penino). He was arguing the static electricity idea while I was advocating
the boundary layer theory.

I am fucking sick and tired of your inane attempts to overturn my brilliant
assessments.

It is quite obvious that you attack me solely because you are jealous.
You know of your own deep incompetence and you cannot accept anyone,
like me, who is superior.

Well, fuck you!

Fuck you!

You are an incompetent idiot and I am the towering superior.

Do not ever forget that.

Oh, you don't have pets then.

You must be living in one of those places that are sterile like in a
trendy jewelry store.

A few years back, kind of by accident, I found a girl whom I knew from
Tehran University years when I had a crush on her. Now she was single
and available, with her only daughter married and away. A chemistry
developed between us fast, both highly educated, both Iranian (thank
God! I was sick of cro-magnons blabbering stuff in English), both
physicists, and with that sweet background from early 1970s behind us;
and this was going to get serious too until I saw where she lived. It
was one of those "jewelry store" types settings in a high rise apt
building, complete with a wide view of Lake Ontario. I dumped her soon
after that!

I remember so well what I asked her just out of curiosity when I saw her
place. "When is the last time your hands have come in touch with dead
leaves? She asked me why? I said because just two days back I gathered
and tightly packed eight 40-Gallon sacks of trash bags with dead leaves."

She understood me, and said she was like that up until 10 years prior to
that but had since changed some "priorities" in life.

I couldn't even breathe in a place like that.

And 25 years prior to that little but special affair, I had dumped
another perfect match for some other reason that had the same sterility
theme about it.

Me: "Why do you keep all the windows so tightly closed all the time?"

Her: "I'm allergic to outside air."

Dumped her!

I wait for the strong winds of November to blow all the

The great part about two Iranians getting together is that even their
vast amount of body hair and the fleas living within get to copulate.

Yeah, I can't imagine living in an apartment or condo, where your
choices of where to be are basically bedroom, living room, or kitchen.
I want a A/V room, a computer room, a basement, a garage, a deck, and
a yard to putz-around in.

People have less and less choice in the matter. Soon, you'll have to
choose between a decent career and a decent home since the former is
exclusive to metropolitan areas where affordable homes are nowhere to be
found. Being a teacher allowed me to live in more remote areas where
homes don't cost your soul for a while, but my wife's career is
inevitably tied to having proper access to the downtown core.

OTOH, "working from home" has become much more of a thing, in recent
years. My daughter works from home 100%.

I even dumped acquaintances whose place of living I discovered didn't
have a single spider, or a dead insect behind the windows. You looked
around and could not find _one_ project underway. Not even one, in the
entire place.

Places like that felt like prison to me. The "jewelry store" ones, like
County Prison. All white and sterile with depressingly dead and sterile
decorations here and there. Perfectly polished shiny metal surfaces,
just like county prison bars are. Everything automatic.

Those acquaintances would never hear from me again regardless of how
they tried.

I fucking burn WOOD for heat in wood burning stoves because I cannot
stand a/c heaters. Too hidden, too automatic. Too much like inside
prisons and in those jewelry stores. That's how I am! That's how my cats
are too. They love to choose their places around the stove as it warms
the place. So do I :)

I have been a different person. Very differently raised and almost
always very differently educated. Different parents. Simply different
from people who can live in sterile places.

In my place, all you ever saw, from the days I was 5 years old and
after, were little or big projects. Both _homogeneously_ and
_isotropically_! Right now I took a look around myself. I see nothing
but projects, isotropically as well as homogeneously. I don't have one
second to lose. Right now I'm gaining back my freshness after working
two hours straight on one of the projects. That's how you got to see
these words.

My alcoholic cro-magnon neighbor, everytime she steps inside for some
silly excuse (read that "So you can fuck me if you want") she tells me,
"People WALK in their places of living, I have to CLIMB over things in
your place."

Anyway, .. Hehe :) Motherboard on a small table.. Hahhahhah :-) Let me
begin with the small table. It would get knocked down by my powerful,
heavy, and unbelievably fast cats once every 10 minutes in my place,
using it as the final platform to catapult themselves toward high areas
right below the ceiling that have enough niche made for them (by
myself). All my desks and tables must be large and sturdy enough to
withstand such constant assults. Hehe :) I've forgotten what a "Small
table" is for... Haven't had one in decades.

And the motherboard? It would only take me one quick trip to kitchen to
get the hot tea from microwave and come back. That's all. It would be
ruined :) You'd see like three different tomcats' urines on it. First
one just to tell me "I'd like to cooperates with you in whatever it is
that you spend your time on." Then the other two quickly joining in to
say, "Me too, don't forget that."

You must have a monitor, no? Where is that? On that same small table?
.... Even on my large sturdy tables I change monitors just about every
three weeks. The second hand store has them for about $20 each. It is
one of my constant expenditures. As regurarly as other bills. Tomcats
urinate on it from six directions, plus the other 12 directions in
between the six! I'm not kidding. Yes, they even urinate to its
underneath area cause they can shoot their urine with a 45 degree angle
upward if they want. I leave it to you to figure out why there are 12
different directions in between the 6.

Result is that the poor thing's bezels and how they're engineered will
give in within about two weeks. The damages work their way slowly from
corners and edges of the screen, and within one more week it covers
enough of the screen to force me to get another monitor.

And this is while I cover the monitors when I'm not using the computer
for an extended amount of time, like in sleep or when I'm out walking or
shopping or working on the lawn or painting and repairing something, or
cooking etc. The tomcats ruin it during those rare moments that I walk
away from it to come back right away seconds later.

Needless to say, a permanent item among my laundry load are the large
sheets I use for covering the computer and monitor. They're always there
together with all the towels I place for them to sleep on, and all the
towels I place on their favorite spots throughout the house to sit on
and enjoy the sceneries. I launder every day. My laundry machines work
about 7 times harder than ordinary mortals. The cro-magnon neighbors,
four of them stuffed in that house, do their laundries only once a week.
I know that because I can smell the stench of the laundry powder they
use and don't rinse enough. When they run their dryer, the whole area
around their house gets full of that stench. Being cro-magnons, they
must be considering it "nice clean smell" and love it too.

"Motherboard by itself on a small table"... Your life is a fiction
compared to mine. I think I'm living, and you're just existing inside
Linux :-)

When I was married we had a house with all of that. We gravitated to the
living room and kitchen. There were two screen porches but we only used
one. The cats enjoyed the other one as they could come and go.

I did use the basement for preparing circuit board silk screens but that
was about it.
