CPU cooling idea, Ferrofluid?

Ferrofluid on the inside of a machined out slot in the base of
a heat sink? With some kind of cap to keep it in?

Ferrofluid is inside of speakers where the voice coil is, it is
a cooling fluid known as magnetic fluid, but it is not magnetic,
it attracts to magnets as it is micro-fine ground iron dust within
an oil (I think) fluid medium. pictures can be seen on eBay.

Any thoughts?

It's a good question but I wasn't able to find a good fun answer for you.

You'll have to settle for that which is all sorts of technical in places and
isn't a whole lot of fun. It does look as though it might be possible (some
seem to wonder of the benefits over water though I've found anti-freeze
works best in the only two water cooled systems I've ever built) but the
cost for the amount used would be an additional expense people might not be
able to justify.

One additional note is that in today's realm OCing a PC to the point where
additional cooling is required is, while certainly less expensive, no longer
an issue with the advantages of product lifespan at normal temperatures and
voltages and PCs being, generally, fast enough. It wasn't that many years
ago that I saw a buddy of mine build one into a freezer for a few extra CPU
cycles and a longevity of a few short months. Granted they went by faster as
far as the CPU was concerned but the resulting burn out cost him a PC that
would still happily be running an older OS today just as well as it did
before he OCed. (Don't get me wrong, I've done my share of voltage increases
and lost my share of hardware and while I do understand the urge to go
faster it's reached the point where I just don't bother any more because
it's no longer justifiable to me. The increased number of cycles isn't going
to make that much of a difference the next time you're at a LAN party with
Halo going on and while it is cool, a lot of fun, and great to show your
buddies it's really not as productive as it once was. In fact, if you want
you can just wait 6 more months and anything you'll be able to achieve for
speed will be commonly available on the market.)

If you ever get your hands on an old AMD K-6 you can have a lot of fun with
that. <g> But it does look like it's possible and should be entertaining. If
it works as well as you hope maybe you could publish the details. You'd want
to take accurate internal temps and benchmarks prior to and after the
installation. Documentation, including images, would be nice too.

Iron is a crappy conductor of heat.

The "cooling effect" of ferrofluid is NOT the
primary reason it's used on speakers, the primary
reason is the damping and centering of the voice
coil in the magnet gap.

This has nothing to do with XP. Ask elsewhere.

In other words, you don't know.

Good ol' Nobody Man, I suspect he's
nothing but a autoresponding app that randomly

No, I don't know. That does not change the fact that this question
does NOT belong here, in an XP group.

What exactly is your purpose with this group? I have not seen one
useful post from you but you do seem to waste a lot of bandwidth
complaining of other people's posts. Maybe you should see if your own
posts meet the criteria for the group.

I give advice here from time to time. I won't speak out of my ass
about things, as so many do, and they lead folks down wrong paths.

What bothers me is the "**** you I'll do what I want" attitude where
folks just post whatever they want, wherever they want, and EXPECT an
answer. If it's not checked, then who is to stop Mary Jane
Rottencrotch from using this group to sell her apple pies?

If it's in the wrong place, it's in the wrong place. You have not
disputed that FACT.

No, I did not dispute that FACT. What I disputed was your wasting
everyone's time saying that the post was inappropriate. At that point,
so is yours. Obviously your post had nothing to do with Windows XP either.
If I see an inappropriate post I ignore it, not waste everyone's time
complaining about it in the newsgroup. If you want to drop a personal
e-mail to the poster that is your business.
Most people in this group and most others have an interest in more
things than just the stated title of the group. While there may be
posts in the group that are not "appropriate", a lot of other people are
interested enough to reply, either with an answer or where to find the
answer. From your attitude it would seem that posts regarding Vista
would be inappropriate in this group, but are they really?

Their header information reveals that they're using XP and the question was
about hardware. While I'm not a netcop I do think that is enough information
to warrant acceptance of the post as being in the correct category.

Humm, that mean any questions posed while in ones office, should be

Nah, but this wasn't quite that generic. There's no specific XP Hardware
that I'm aware of. There's Microsoft hardware such as keyboards and mice for
instance. But this was a hardware related question in what, from initial
appearance, would be a hardware related group. So, in answer to your
question, if someone were to post a very off topic question in the office
group (even if they did so from home) I'd answer it regardless if I knew the
answer. If I didn't know the answer I'd move along. If it was way off topic
and I knew the answer then I'd post the response and a notation that they're
asking in the wrong spot though if I didn't know the answer I'd move along
and after a day or two of no one answering I'd likely point them to a more
appropriate group if there was such a critter.

I think that a lot of people don't know where to post a question, and
considering the number of different groups I can see why. They can only
post to a group they know of and hope for an answer or a pointer to the
correct place to get the information. Replies of Google or don't post
that type of question here makes the group look elitist and only drives
away those who need help.

I agree. If one knows the answer one shares it? No matter when/where it's
asked??? Elite? I'm a four time (now) college student. LOL My prime skills
are catalogueing the problems and retaining the information and in
searching. My primary abilities are breaking my own computers and fixing
them. My background is in UNIX and it wasn't until 98se that I started to
even find a mouse. I'm not here to show anything but to answer questions or
ask them when I have them - and believe me I have had loads... (Spent ages
finding a decent GREP and gave up for instance.) There's so many choices
(and choice is good) that you haven't much choice but to poke and hope a lot
of times from and end-user view. Web interfaces for usenet are often
misleading. So, I answer where and when I can.
