Heat from heatpipes probably damaged a memory chip....

Hello,

Accoring to memtest86+ at least one of the memory chips in Skybuck's
Dream PC from 2006 is damaged and has a bit error.

It turns out the memory chip was *new* from corsair which means it was
not touched by the plastic sticker tape incident.

This probably means that the bit error could have been caused by heat
expelled from the heatpipes of the top down cpu cooler (Scythe Zipang
CPU Cooler).

I have taken some pictures to show you guys and to get some response
from what you think killed it... (I am pretty convinced it was heat
from heatpipe and will probably change the orientation from the cpu
cooler again ?! hopefully for the last time... Wink I am not sure if
it's possible though but I might give it a try.)

Long ago somebody recommended I place the heatpipes near the big fan
at the top... now I kinda wish I had done that from the start it might
have saved a lot of damage...or maybe not ?!?
But now I think it could have... maybe sucking away air around
heatpipes is a good thing...

Anyway here are the pictures:

I was also wondering if it's maybe possible to not use dim1 which is
closest to the cpu ?!?
I doubt it though...anyway I think it's best to get those hot
heatpipes away from the memory chips...

I guess this was also kinda a experiment to see what would happen and
yup after many months... a memory chip got damaged ! So that pretty
much confirms the experiment for me: "heatpipes near memory chips not
a good idea ?!"

Let me know what you think and peace out !

For me this is becoming a drag... I have fixed this pc so many times
it's starting to bum-me-out.

Feels like I am fixing a formula 1 car or dragracing car all the
time ! LOL I am kinda fed up with it ! ;)

Heat is a killer that's for sure ! My next PC must be a "cool" and
"low heat" and "low power pc" otherwise I will go nuts ! Wink Smile (And
hopefully have still somewhat decent performance Wink)

Bye,
Skybuck.

All those pictures show is that you live in a dusty environment and either
don't have air filters on your PC, or don't clean it enough.

Which gives me a new interesting theory:

The Scythe Zipang is a top down cooler... which could mean it blew
dust into the memory chips from above... and somehow that tiny little
bit of dust caused a short circuit in the memory chip ! ;)

Another theory/hypothesis which I am slighty worried about is the
following:

"Water vapor from the dust filters was blown towards the memory chips
and was blown into the memory chips which caused a short circuit".

Not so long ago I cleaned the pc-case dust filters while the pc was
running... I decided not to dry the dust filters thoroughly because a
kid on youtube also didn't try them thoroughly... I just made sure
most of the moisture was gone... just little bit of moisture was left.

So I wonder if it's possible for tiny little micro drupplets of water
to float through the air and kill a chip ?!?

To me this seems unlikely but reality is usually more strange than
fantasy ! ;)

One last theory/hypothesis which I already wrote about in the past is:
"pc is not grounded, and me touching pc causes static electricic
feedback into the pc, since motherboard(s) is/are known to have some
leakage, so reversed path seems plausible".

I will probably call an electrician to check out and change the power
sockets with "grounding power sockets"... I am curious if he will
discovery anything about the power sockets... like maybe no grounding
wire present :)

Skybuck.

Not unless the computer was next to a busy metal lathe or milling
machine.

Real, can't find the video of the kid...

But search for antec 1200 and you'll see plenty of people washing their dust
filters with water ! ;)

Makes ya wonder doesn't it ! Wink :)

Nothing wrong with that as long as you let them dry out.

But then one needs to wait... which is "down time"... and might be
unneccessary ?
(Also cleaning it dry takes more time and toiletpaper ! Wink)

The real question is:

What happens if it's slightly wet/moisturish ;)

Anybody know ? Wink Smile =D

Bye,
Skybuck Wink =D

What happens if you just run the system without the dust filter on
until it dries? Would it be so bad? Oh wait, why not get extra dust
filters so you can rotate them out for cleaning...

Go buy a REAL blower system, place it in the next room, or in the wall,
and filter THAT on the intake side, then ALL the air it forces into the
PC will be clean, and the only difference is the pipe (hose) leading into
the PC from the mystery location. 4" Pipe should work well.

Then, you could use an automotive filter on the front end of the thing.
The highest tech consumer level filter you can get, dollar for dollar.

Goddamned overtly retarded cross posting DUMBFUCKS!

Sorry,Zootal... I've been dealing with "real world" printed circuit
boards a long time. I might even venture that I was possibly repairing
them before you were born.

I've repaired marine electronics from sunken boats, portable two-way
radios found in sewers, pagers that went swimming in toilets, dispatch
consoles that have had the "Pepsi Treatment" (lattes and mochas are
worse..but "PT" is the generic term), and radio base stations doused in
rat pee for years.

I know what can happens from "exposure".

Yes, early PC mobos were "bare-assed traces", but any reasonable mobo
made in the last 10-15 years has some form of coating. Your "finger
touch" doesn't fly.

It is possible you were repairing them before I was born. If so, that would
make you upwards of 75 years old. I've met older people out here, so I
suppose that is entirely possible. But don't tell me what is and is not out
there. Yes, there is a lot of nicely made boards properly coated etc. etc.
But I stand by my statement - there is a lot of stuff with "bare ass"
traces and worse. Once you get out of the realm of your pretty consumer
grade electronics and move into the world of military and custom (and
not-so-custom) commercial equipment, you see a stunning range of quality and
reliability - good and bad.
