Me and white heatsink goo have a very bad working relationship. I only have
to walk into the workshop when there's something on the bench using it, and
all of a sudden, I'm covered in the rotten stuff, without even going near
the bench. At least it seems that way ... :-\

I once got in a lot of trouble with my boss when I was young and worked for
a U.S. based company. At that time, I didn't understand that there was a big
difference between British 'tongue-in-cheek' humour, and the much more
direct U.S. type. I was talking on the phone to one of the designers of a
piece of equipment that we sold here in the UK, and asked the guy if he
could arrange to send me some screws for the cabinet, as they were a thread
that we didn't readily get over here. He asked if I knew exactly what size
they were so I replied, quick as a flash, thinking that I was being funny,
"I guess that they are round about 3/16ths APF." "What's APF ?" the guy
asked. "American **** Fit", said I ...

Stony silence on the phone. Half an hour later, I was summoned to the boss's
office. Apparently, the guy had been really offended by this, thinking that
it was a slur on what he considered to be good American engineering, and had
called my boss to complain about me. Just goes to show how easily offence
can be caused between nations, even when they speak what's basically the
same language ... :-)

This is something I'm currently wondering about. I have a fridge-like
thermo-electric cooler than has two sections, top and bottom, with
different temperatures. The top suddenly stopped getting cool at all, so
I took it apart to figure out why. The fans and voltages were all there
so I broke down the heat sinks on the bad one to get to the Peltier
device. With it isolated, I powered it up briefly and much to my
surprise the Peltier device got hot real quickly with the opposite side
getting cooler. So the device works, it has to be something with the
heat sinks?
They did use white goop on both sides, but very little and it was
already dried. The heat sinks are milled flat where they make contact
with the Peltier device, so my thinking is they need new goop.
Looking around I found that Star heat sink compound is about the best
you can get, so I ordered some. It just arrived the other day so I'm
planning to clean up the old goop, put on some new goop and hope for the
best. I don't think too much would be an issue in this case, I want it
as cold as possible.

As long as there is no liability involved. If someone else opens it

We have that kind of humor in the US too.. But only amongst friends or

Too much of the stuff will be a problem whether you are trying to heat or
cool. I have some major doubts that a thin coating of that stuff would be
enough to make any major difference in the performance of peteler junction.
Now on the other hand, if the heatsink is loose... That could give you some
real issues.

Michael is quite correct.

The thing about heatsink compound, is that you should only use a
*very* thin layer, and use it between surfaces which are already flat
and well-fitting. Adding a thicker layer of heatsink compound than is
necessary, will actually reduce thermal conductivity.

You want as much direct metal-to-metal or metal-to-ceramic contact as
you can get - enthusiasts who "overclock" their PCs will often flatten
and polish the top of the CPU and the bottom of the heatsink to
increase direct contact. A *thin* smear of heatsink compound is
appropriate... just enough to fill the remaining gaps between the
heatsink and the heat-sunk :-). You almost want to smear it on, and
then wipe most of it off gently with a single-edged razor blade, so
that there is no excess buildup between the two surfaces.

And, yes, if the heatsink actually comes loose from the Peltier
junction (e.g. if it was originally spring-clipped in place, and the
clips are loose or have fatigued and lost pressure) then you've got
problems... you'll get a layer of air between the two surfaces, and
thermal conductivity will become quite poor. Adding a thicker layer
of goop to try to fill the gap isn't the right thing to do - instead,
fix whatever caused the devices to become loose, clean the surfaces,
reapply a *thin* layer of compound, and secure the devices back
together with the proper amount of pressure.

If there was (apparently) nothing holding the two surfaces together -
no clips or retainers - then you're probably dealing with a "thermally
conductive adhesive". Some of these are good, some are poor... and
you'll have to strip off all of the remains, and then reapply (again)
a very thin layer of a suitable thermal adhesive, and fasten the parts
back together with appropriate pressure until the adhesive cures.

Yes. Knowing the U.S. and its people much better now, as I tend to visit
twice a year and have now for many years, I would say that was pretty much
spot on. Although I've found that American people are much more friendly in
general to strangers, than people over here are, I also find that they are
much more 'reserved' in actually getting to know them as a friend. Here in
the UK, if you are just in the same business as one another, you tend to
automatically think in terms of communicating with a 'kindred spirit'. So
even on a first contact with someone, if you appear within a few sentences
to be speaking the same language, it becomes quite acceptable to introduce a
degree of 'chuminess' into the conversation such as calling the person
'mate' and such-like. Barbed humour between you is then immediately
accepted, and is likely to get thrown back at you by the other person, and
often gets deflected onto the company that you, or the other person works
for. Having made the 'APF' comment to the guy, in my naivety, I was
expecting him to just throw back a similar comment like " so what, then ?
Your British threads are better than ours, are they ? :-) "

Like I say, easy to cause unintentional offence, if you are not familiar
with the country, and it's people and their cultural differences, even if
they appear to speak the same basic language. Many countries in Europe speak
English as a second language. If you speak it to a German for instance, in
general, he will not understand British humour. Not likely to be offended by
it. Just won't understand it. A Frenchman, will understand it, and be
offended - or at least pretend to be ... OTOH, a Dutchman will both
understand the humour, and give back as good as he gets. They seem to have a
very 'English' understanding of the English language. I don't know why that
should be, but I was once told by a Dutch guy that I had dealings with, that
it was because they easily received UK television over there, so tended to
watch a lot of British made drama and comedy programmes. I wonder if this
will change now analogue TV is almost now all gone. I bet that they don't
receive the digital multiplexes across the water, anything like as well as
they did the high power analongue transmissions. Any Dutch people reading
this care to comment ?

There's a good one. Especially when the humidity is very low, and the

Low humidity is rarely a problem in Florida.

It's hard /not/ to interpret such a description as an intentional
insult. I can't imagine what it actually means -- in any innocuous
sense, anyway.

There ya go then!

Please don't semi-quote Ronald Reagan. It's not becoming.

If I'd been in a debate with Ronnie, and he'd pulled that "There you go,
again" crap with me, I would have ripped him a new one, even if it cost me
the election.

(This is way OT, but remember last year when Barney Frank ripped into a
stupid woman who was griping about Obama being Moslem? I was proud to be
queer. If all politicians -- conservative or liberal -- were that
intelligent and quick witted, the level of political discourse in this
country would be at a much higher level.)


Anyone from the UK would see it as a quick-fire throw-away
line, and would laugh at it. It's sort of intended to be 'barbed',
but not in a malicious way. It's a very hard to describe form
of humour that is quite prevalent over here.

I admire someone who can come up with quick throw-aways -- but unless they
make them all the time, it's hard to tell they're supposed to be humorous.

I offended people with "innocuous" wisecracks so many times that I gradually
became careful about what I said. A word to the wise...?

If you cut yourself on barbed wire -- you're cut, regardless of how you came
in contact with the wire.

And, yes, if the heatsink actually comes loose from the Peltier
junction (e.g. if it was originally spring-clipped in place, and the
clips are loose or have fatigued and lost pressure) then you've got
problems... you'll get a layer of air between the two surfaces, and
thermal conductivity will become quite poor. Adding a thicker layer
of goop to try to fill the gap isn't the right thing to do - instead,
fix whatever caused the devices to become loose, clean the surfaces,
reapply a *thin* layer of compound, and secure the devices back
together with the proper amount of pressure.

I agree. The assembly goes like this:
Small heat sink (cold side) - square plastic gasket with embedded rubber
seal that doesn't physically touch anything - square block of Styrofoam
with a square cutout in the middle - Peltier device - foam tape around
the styrofoam - large heat sink. To screws go through everything on
either side of the Peltier to sandwich it all together.
And oddly they hot-glued the ends of the screws and nuts.

This is obviously made in China, everything is pretty crudely
manufactured and assembled, heat sink fins were mashed together in
spots. I didn't think to check the tightness of those two screws when I
took it apart, but I bet you are right and they weren't nearly tight
enough. I'm going to rebuild the 2nd one while I'm at it and will check
the tightness after I pry off all the hot glue...

I once got in a lot of trouble with my boss when I was young and worked for
a U.S. based company. At that time, I didn't understand that there was a big
difference between British 'tongue-in-cheek' humour, and the much more
direct U.S. type. I was talking on the phone to one of the designers of a
piece of equipment that we sold here in the UK, and asked the guy if he
could arrange to send me some screws for the cabinet, as they were a thread
that we didn't readily get over here. He asked if I knew exactly what size
they were so I replied, quick as a flash, thinking that I was being funny,
"I guess that they are round about 3/16ths APF." "What's APF ?" the guy
asked. "American **** Fit", said I ...

Stony silence on the phone. Half an hour later, I was summoned to the boss's
office. Apparently, the guy had been really offended by this, thinking that
it was a slur on what he considered to be good American engineering, and had
called my boss to complain about me. Just goes to show how easily offence
can be caused between nations, even when they speak what's basically the
same language ... :-)

I think it matters in what part of the U.S. this person resided. I'm
originally from the North East and humor that would be considered mild
there is considered a great affront to some people in the South.
However, racist remarks, that I find offensive, don't seem to bother
their delicate constitutions. Chuck

We have that kind of humor in the US too.. But only amongst friends or
people you know fairly well. If a stranger uses sharp humor with me (some
do) and It gives the feeling of you dont know me well enough to be poking
humor at me, and we also usually take the fact there is ususaly truth in
humor.. And honestly you probaly think the US standards are idioic and
stupid to still be using when the rest of the world is using the metric
system. Thats the feeling I get here in Japan at least. People cant
understand why the US uses the old system still.

Anyhow.. Just my $0.02


Yes. Knowing the U.S. and its people much better now, as I tend to visit
twice a year and have now for many years, I would say that was pretty much
spot on. Although I've found that American people are much more friendly
in general to strangers, than people over here are, I also find that they
are much more 'reserved' in actually getting to know them as a friend.
Here in the UK, if you are just in the same business as one another, you
tend to automatically think in terms of communicating with a 'kindred
spirit'. So even on a first contact with someone, if you appear within a
few sentences to be speaking the same language, it becomes quite
acceptable to introduce a degree of 'chuminess' into the conversation such
as calling the person 'mate' and such-like. Barbed humour between you is
then immediately accepted, and is likely to get thrown back at you by the
other person, and often gets deflected onto the company that you, or the
other person works for. Having made the 'APF' comment to the guy, in my
naivety, I was expecting him to just throw back a similar comment like "
so what, then ? Your British threads are better than ours, are they ? :-)
"

Like I say, easy to cause unintentional offence, if you are not familiar
with the country, and it's people and their cultural differences, even if
they appear to speak the same basic language. Many countries in Europe
speak English as a second language. If you speak it to a German for
instance, in general, he will not understand British humour. Not likely to
be offended by it. Just won't understand it. A Frenchman, will understand
it, and be offended - or at least pretend to be ... OTOH, a Dutchman will
both understand the humour, and give back as good as he gets. They seem to
have a very 'English' understanding of the English language. I don't know
why that should be, but I was once told by a Dutch guy that I had dealings
with, that it was because they easily received UK television over there,
so tended to watch a lot of British made drama and comedy programmes. I
wonder if this will change now analogue TV is almost now all gone. I bet
that they don't receive the digital multiplexes across the water, anything
like as well as they did the high power analongue transmissions. Any Dutch
people reading this care to comment ?

Its actually funny the fact that we speak almost the same language. Although
I am an American, I currently live in Japan. The fact our languages are so
different, provides some kind of cushion for misinterpretations, well
usually.. I try to take things people say without getting offended, even if
they seem to be offensive in English. I understand that there is a language
barrier and also a culture barrier. Many people mutually understand that
when I am talking to them in Japanese as well.

So my point is we are so alike, Brittish and Americans, that we assume that
nothing is different..

In the UK, modern cars use metric threads. Ones from about after WW2 to
the '80s mainly UNF and UNC. Pre WW2 BSW and BSF. BA was common for
electrical stuff.

A classic car is really just any which isn't recent and not defined under
the strict headings of vintage etc. It isn't restricted to any make - just
over 20 years old. Although that age isn't agreed by everyone.

In the UK it probably means BSF and BSW threads perhaps brass or cyclo as
well

Some large color TV consoles built in the '60s had 20 to 30 screws.
