comeon people nobody has posted in a wile!! this project does have a due date u know

edit: not trying to demand but if u have a thought dont hesitate to post it

[spartansith]

my block design is around 2.51968 inches by 2.51968 inches, this is just the design, ill put in the mounting holes later, i left room for them!!

If you look att WW you will see that the fins are located right over the core. This is where you want the most cooling. Consider your design so that the fins is not cituated to long way from the core because they will not do any good out there. They will only add flow restriction to the block.

If you are going for some kind of cascade design in the middle of the block, then I guess you could remove the fins totally.

hey, if you guys know nething about air cooling, i goto the same school as laney and i am doing an airduct project. heres the link for my thread: http://forums.procooling.com/vbb/sho...9615#post99615

This is your project: where are YOU at, and where are you going with it?

The advice above is good: if you're not going to cool the area outside the core, ditch the extra fins, and concentrate on the center area.

By now you should know how you're going to make it, with the tools you have available. (or more specifically, what your dad is able to do, and how he's going to go about doing it).

To join the 4 outlets, use "Y" hose connectors. One to join the left side outlets, one to join the right side outlets, and one to join both "Y"s. It's not going to be pretty, but it'll work.

Otherwise, you might be able to find a 5 way tee at your local plumbing shop (kinda rare though).

Machinists (even Dads) are accustomed to detailed scale drawings. And we could give more specific advice if we had a better idea what you were planning.

[spartansith]

well i would put my design that is detailed up but im afraid that someone will take it , its really detailed and to scale thats y i put up one that isnt to scale or detailed.

my dad is a machineist

o and y should i do away with the fins, i have been told my design(detailed one) is good.

thanks,
Laney

[spartansith]

o and im using the new prescott core for the P4 when it comes out, so the fins in my plan are in contact with the core i believe, the center is a circle and its radius is 56mm so if i can find out the dimentions of a P4s core, which is not actually the core but a protective metal that lies on top of the core.

thanks,

Laney

Welcome to our forums! I must, however, warn you a bit first.

Please take this in the light of constructive criticism. If you want to fit in with this crowd, you might want to be a bit less demanding, and spend some time asking questions about theory so that you can understand, rather than asking for a finished design to be handed to you.

Also,

I wouldn't worry about that. Really. Do you really think your design is so much better than the designs of the people here? The odds of that are low, I have to say. Possible, but low. How long have you studied water cooling? Any classes in thermodynamics yet? Have you done any FEM studies on your design yet? Do you know what a Reynold's number is? Have you optimized for boundary layer thickness? This is not to say that you haven't. But a lot of the people designing waterblocks in these forums HAVE some or all of these. Plus, practice makes perfect. They have made many different waterblocks.

Now, on the other hand... if you share your design, you might actually benefit from the kind people who are willing to critique your design to help you improve it. We are not engineers to be commanded to perform, but there are many generous people who share their time and experience.

The best waterblock that I know of (the Cascade by Cathar) was made in an openly critiqued fashion. He shared all the details, knowing that the final product would be better and that people would benefit from what he learned while designing it.

Your choice.

P.S. I have seen very little newbie flaming in this thread, and I'm proud of y'all. Hopefully, this will be seen as constructive criticism by spartansith rather than an emotional rant, so that he can fit in well with our community.

[spartansith]

i have spent around a month reasearching and tweeking my design, i am in the process of re-designing the center where the water is 'jeted' in, im not a nOOb.

[BladeRunner]

Maybe you should re-read Brians256's thread to you again, or over & over until you take it in, because your reply to it, and the attitude that you present generally, (whether intentional or not), shows either arrogance, or lack of respect and is basically why you are not getting any help or input. People here including myself will help you if you ask in the right way and don't come across a demanding or arrogant, otherwise they will probably just ignore you and move on to the next person that shows some understanding or appreciation.

Hey ppl. Not been chattion for a while, though i have been keeping up with the threads. Just out of intrest, dose the thread for the cascade design still exsist. If so, can some 1 point me to it plz. I've done a search to no avail. I am intreasted in lookin at all the best designs to try n get an idae to wot exactly is amkin a good block, n seeing if there is somethin that has been missed bout water block design, nthen mayb i can help our lad out here with some ideas! And create my own, I have a few, but need to c more designs to see there potential effectiveness. Thanx as always in advance.

Edit: I reall should get round to changing my sig, lol!

[BladeRunner]

There have been quite a few on the Cascade and the design behind it, Here's a good one, A search for "Cascade" username "Cathar" should find you more here, and try also at Overclockers.com forums

[spartansith]

im srry for how u take my reply, im new to forums, and i wasnt trying to be rude.

o and bladerunner where did u get those copper barbs, i think thats what u call 'em, with the blue ring on them?

[spartansith]

and the MS Paint pic of my wb is very vauge, it has the principle though

[WAJ_UK]

o and im using the new prescott core for the P4 when it comes out, so the fins in my plan are in contact with the core i believe, the center is a circle and its radius is 56mm so if i can find out the dimentions of a P4s core, which is not actually the core but a protective metal that lies on top of the core.

You will find the dimensions for all CPU's from the technical sheets on the manufacturers website.
By the circle do you mean the blue elipse in your drawing? If so a 56mm radius is going to be huge.

well i would put my design that is detailed up but im afraid that someone will take it , its really detailed and to scale thats y i put up one that isnt to scale or detailed.

I would only worry if your planning to take it into production

so could someone get me the WW blueprints,

I asked something similar to this last October about a few blocks (to no avail) because I wanted to create CAD models of existing blocks to compare with my design in CFD but I quickly realised I didn't have time to teach myself how to use the software. You can get a really good idea of the dimensions from photos though just print them out to scale and measure them

[BladeRunner]

The P4 IHS just gets in the way really, for the sake of expliation you can liken it to putting a 1mm copper shim between the core and your waterblock if you were using an exposed core CPU, (like AXP). As you can imagine in doing this you just create an extra thermal interface. People usually find good temp gains when they remove the IHS. Unfortunately some of the newer P4's are bonded to the core and will be destroyed if the IHS is removed.

Accepting the above, on the design you sketch the fins probably wont help the cooling, because they are to far from the heat source. with a waterblock, (assuming decent flow rate & pressure from the pump), the majority of the cooling effect wants to happen as near to the core as possible, and this is how the performance gains are achieved. It's a very complex subject and one I only have a passing understanding of so it's probably better to let others with greater understanding explain it in more detail. in layman's terms for an overview only, If you think about it in a logical way the further the heat from the CPU core has to spread out in the block before it is transferred to the coolant the hotter it will get at source. If you can transfer the heat to the coolant as close to the core as possible with efficiency, it will heat up less. To remove the heat efficiently as possible in a small area is not easy, and that's why is takes intricate, complex designs like Cascade to achieve it. Although it sounds as if Brians256 has swallowed a flow dynamics book for breakfast those are the types of things that would be considered when designing a high performing CPU block now.

As said before you are very unlikely to get Cascade or even white-water performance, but you may get near, post the detail design you have and then the experienced can point you in the right direction.

The blue toped fittings I use on the 4 outlets of the "Splitter-X" (and 6 other system blocks), are 8mm Push fits. They are designed for pneumatics (10bar rated) made by Festo. The festo type I use are plated brass, with a thin stainless sheath.

www.festo.com

There are many other makers, I also use some made by www.Norgren.com

They work well I've had no leaks or tubes come out in use. They must however be used with the correct type of tubing, (no vinyl or silicon). I use a polyurethane transparent and it works well.

[spartansith]

thnx for the info on the outlets, and i am thinking of selling these if they turn out good, i might draw out another general idea of the design for yall!

thnx,

Laney

[spartansith]

is it possible to keep the humidity down in ur PC by putting some silica in it or something like that that companys put in the shoe boxs?

[superart]

yea, but you will need A LOT of that stuff, and if you dont cool to sub-ambient tempertures, which your not, it is pointless

[pelle76]

You will find blueprints of the WW here I don't know if they are originals and if the dimensions is exact.

Its in swedish so just click on the link "vattenblock" in the upper left corner and the scroll down a bit. There you'll find the WW.

Humidity? Are you going to use a peltier? Otherwise plain simple watercooling will never go below ambient, thus you will not have any problems with condensation. (other than Bong-cooling, that is)

[spartansith]

i dont need any dimentions now, i have made my own

o and that was just a thought, for those who were talking about it somewhere, i forgot where...

thnx, Laney

[sn_85]

so when exactly is this due date that you keep pushing us to?

i understand that you are getting this watercooler for the CPU, GPU, Northbridge. You also goto a private school and are purchasing a Prescott (which is worse then the Northwood, but i wont get into that), and 9800XT. why are you going to then skip on pump? $40 seems really low considering those 3 components will cost a thousands bucks. are you going to risk using an unrealiable cheap pump on this system? can that pump handle the heat output of your system? the only pump thats around $40 could be the Hydor Seltz L30. or the Via Aqua 1300 but those seem to have impeller issues and quality issues. i suggest you get a cheaper videocard or cheaper cpu and shell out the bucks for an Eheim or a Iwaki pump. it's worth the investment and it will out last your computer. u state your radiator is metal, what kind of metal? make sure you get a copper one

[spartansith]

i got the heater core for free, i think its alumminum, and the Prescott core isnt even out so how do u know its worse than the Northwood, and it has a 1mb cache, it will even reach 5Ghz later with the socket 775, and also its not going to cost $1000, more like $780 for the asus 9800xt and new 3.2 Prescott.

im thinking of just cooling my processor b/c i dont want to fool around with the GPU and its shim/heatsink b/c one of the reasons i chose the Asus' 9800xt is cause of the cooling fan bonus. also my chipset can do without.

i do plan on OCing this my CPU and GPU, the new XTs have a built in sensor for OCing, and my current m/b has a program also to use in Windows, or i could OC in bios, which one do yall think, my mobo is Gigabytes GA-8KNXP!(cost me $240 retail brand new)

thnx, Laney
