the silicone worked out quite nicely, it makes the whole thing look as transparent as one solid chunk of polycarb.
I've found it does tend to attack the galvanized bolts somewhat, probably only whilst its drying out though.

the needles protrude about 1.5mm into the holes - look pretty centered if ya ask me

maybe??
Shut down your pw and install that thing man
although maybe you should test it first on an old cpu or something

(and with high temp -->shutdown feature) just to be sure.

but if i look at your pics, your holes are pretty small compared with the capillars you put in...

hey, yeah, got a question? does anyone know if you can get hypodermic needles in the US like that, cause I don't think you can do that here. If not, any ideas for alternatives?

edit: and i do mean in a legal way

go to a doctor, veterinarian, hospital,...
(most chance with a vet or hospital because they do operations, doctors don't do operations so i guess they dont have such advanced stuff... 100% sure you'll find some in a hospital )

Dieter: Short answer, yes (for me it works, have a look at the graph)

Long answer: I have no idea how it would compare to any other waterblocks. What I can say is that it walks all over my modified taisol heatsink (80mm papst fan). But then "c'est normal" as we say here!

FYI, cpu is an Athlon 1800XP and mobo is k7s5a - running @ 133/133


grvydude: (wild guess) you sure you can't order online?

edit: (oops) forgot to mention that the temps are for full load running burnK7, as reported by MBM5 for the cpu in-socket sensor

So the highest temp of that graph is after a long while of 100% stress?

(I don't see the point of a cpu temp/water temp curve)

well i understand where to get it, I know many doctors, many in my family, thing is they say it is illegal to sell hypodermic needles without a perscription here in the states... Anyone to back it up or tell me another source? (once again a legal source in the US)

The graph gives you the cpu temperature in relation to the water temperature. Ideally you would want the cpu temp to be as close as possible to the water temp. Here you can see that this is not the case (and never will be, no matter what waterblock you use).
The graph shows that the difference between these two temperatures is not constant

At the moment, my radiator is just a large bucket of water. From the graph, you see that if the water never rises above 30°C, then the CPU will never rise above 42°C (this is pretty much the case now)

If I used a really efficient (large) radiator instead of a bucket, then the water wouldn't go much above the air temperature (17-18°C), so the CPU would remain below 35°C.

That is illegal?? Some anti-drug thing or something
Just explain them its for a waterblock



Lolito_fr what is the max temp your water/ cpu gets on 100% stress for a while, and with which roomtemp?

30° water and 42° cpu?

[Political rant warning]
For those living in Europe, who aren't aware of this sort of thing... Our government here in the land of the not-so-free United States decided many years ago that we were to stupid to be allowed to make our own health care decisions and initiated a "War on (SOME) Drugs". As part of this war against readily produced, non-patentable, low profit margin substances, the decision was made that except for a few limited effectiveness drugs, it would be necessary for the average citizen to get the governments permission to care for any serious illness. This permission is given out (for a healthy fee) by government licensed people who are allowed to put "M.D." after their names. Part of this restriction includes a strict prohibition on sale or possession of hypodermic needles by anyone not having a gov't license or a permission slip from a gov't licensee. (Have to do something to encourage addicts to kill themselves of by making them re-use dirty needles)
This helps to ensure large profits for pharmeciutical companies, and helps to keep the crime rates high enough to ensure that police forces get plenty of funding and protect insurance company profits.

What this means for those wanting to duplicate lolito_fr's design in the US will need to either get the needles from an illegal source, or convince a friendly M.D. to give them permission to build computer hardware....

Its a crazy world... I cant get needles to make a waterblock because a small number heroine addicts use them to kill themselves with

I'm sure there are alternatives... I have seen coffee straws used before... what about turkey basting needles? Or are they too big...

You could always ask a heroine addict if you can have their old needles

EDIT: ebay is always a good source for illegal sales of banned goods

http://cgi.ebay.com/ws/eBayISAPI.dll...&category=3179

Located right in my home town too... how convienent and cheap, but you will have to find someone with diabetes to order them for ya.

EDIT2:http://cgi.ebay.com/ws/eBayISAPI.dll...&category=1210 doesnt require a medical problem to bid

The rant is based on fact... however... the applicator I got for my liquid arcrylic glue has a hypodermic needle tip that is flat (read not usable for injecting into people)... I'm sure these could be procured in other sizes as well... just look around a bit.

Like this and this and even this.

So don't say you can't get them legally... just say you have to look.

Looks like I may just have found a market for exporting the things lol

7$ a piece, compared to 0.06€ = nice markup

My first set of needles came with an inkjet recharge kit; for what its worth

Yes, recharge kits are another source, I was only showing other sizes... I don't think the diameter is the same as the one's you had. I didn't find the size reference as I was just making the point that they COULD be found legally.

check out lmno engineering's website ( http://www.lmnoeng.com/ ), for the formulaes to calculate the flow restriction of an annular outlet, or more specifically, to convert an annular (ring) "pipe" to a round one.

You'll find that the gap has an equivalent hydraulic diameter, hence my comment. You need to keep the exit velocity under the inlet velocity, otherwise the inpingement jet won't form.

I know it seems counter intuitive, when you look at the corresponding surface areas, but you can't beat the physics of it.

That's because if the exit velocity was higher then the inlet velocity, you wouldn't have enough pressure to smash the boundary layer, right?
(if the water gets away too fast you cannot create pressure)
