advice on my CPU block design

[naS]

hola ,

im plannig this CPU water block , and i want u experts make an opinion about it ..
do you think it will work good , great , sucky ?
what thingys do you think needs to be improved ?

i would also like some info from you guys if u dont mind , about the intel , A64 cpu sizes , i dont want the block to cover half the cpu u know ..

where are the holes for the new soket mobos , is it even possible to make a block that will fit all the and,intel mobos ?

*** Dont take the mesurement too harsh , its still the first alpha , its all changble ***

It looks ok. I would make it a little smaller, because the die you have to cool is really small and there is no need to make a block an the pins/fins bigger than the cpu socket, because making it bigger would decrease the efficience (i just translatet the word free from german, is it right?) of the surface. Smaller surface only in the midle with some jet impigments have a very high efficience and can perform better than big blocks with large channels an much surface, but very bad efficience of the surface.

Second i would use some small jets like the cascade exact there where the die will be under the block (about 10-20 1,2mm holes would be perfect). The size of 1,2mm prooved best in tests with an eheim 1250 an 1/4" tubing, so this would be a good choice. To have an ideal pressure on the jet holes, it is good to have whith all holes 30% of the sqare surface of the tubing. Many people drill too much holes to increase flowrate, but thats not exactly the way to good performance of the block (it needs pressure!).

This is for your other questions:

you might find that patern very close to impossible to manufacture, also very costly in dremmel disks, if you where to alter it so that you can cut the paths with one.

thanks for the link and the transletion , ill try to modifay the design when ill have time ..
btw , are the maze i built is too restrictive ? i think i should change the small channles from 1mm to 2mm ..

@rotor , i think the 1mm chan is the only dificulty over here , the machinary is not a problem at all , i have a nice "lil" CNC machines at pa workshop .. the thing that might be problematic is that the 1mm driller is so breakble :E

also , what hight would be the best for thouse pins ? i thought about smt in the area of 1cm , sounds ok ?

[rundymc]

1cm is too high

the design won't be effective cos the pin-free space is totally exposed to the pin area at all sides- so what's to stop water taking the path of least resistance and give drastically lower flow in the pin area
I'd suggest basing construction of the DIY LRWW's except with pinfin's

[naS]

mmmm yeah didnt thought about it that way ..
ill try to keep working on it and try to divaid the water curse to some stady routes , just i dont have a freaking moment of rest latly with all thouse damn tests :\

I go with hole depth = 0.9 through 1.2 of hole diameter, barring there is enough material for such dimensions, of coarse...

but it's really not set in stone...

[naS]

0.9 cm would be my guess ? and 12mm is pritty big no ? , im thinking of moding it to some kinda of canals like the WW , but with the same holes pattern as the above to cut into the channles , ill try working on it this weekend where i will have lilbit of time ... what size shall i strict the center too so it will be above the core ?
the site davidzo is great for the sokets holes , but it dont give the size of the cores itself , i can mesure from my barton , but if i will have the size of the P4 and a64 the barton should fit right on ..

[naS]

sorry for the dubble posting , but here is the new version ... i call it: tantantanta , Weee Beta v2.0 !!!

:P

is it just me or the block too big ? O_o

rofl forgot to add the pic ..

[AngryAlpaca]

It can be up to 66mm wide. Now, I'm not too sure about this block design stuff, but wouldn't it be better to have the channels matching each other, rather than bending the opposite way? So it's SSSSS rather than S2S2S2S2.
-- SSSSS 2S2S2S2S (imagine that those are continual patterns. It's hard to draw with text)

No no you miss understood.....

I ment hole diameter*0.9 it's a ratio....

so if the hole is 5mm in daimeter it's depth would be 4.5mm (for 0.9)
or 6mm (for 1.2)

yeah now its all clear , AngryAlpaca i think u missunderstood the design , it does go as an "infinite S " ..

as i saw in the pic , the soket itself is 5x5cm , if the block is vertical , there shouldnt be a problem passing the 66mm , unless its by faar too much and then u go and geting stuck in some ressistor..

tell me if im right here please , i dont wona finish building the block and then find out its too damn big



too bad my mobo is RMAed so i cant take any mesurments :\

[naS]

here we go



i dont think it will fit the intel , the new a64 cpus :\
thier core lookin too big , the width is like only 30mm , i think it wont be eanght to cover the core :E

Not that I have anything to add to the block design, I just like the pic you made in your cam software. I been wanting to get MasterCam for some time now, its just not in my current budget. Good job on the cad/cam drawing!

[naS]

thnx ..
my mom useing it for a few years now , so she teaching me here and there the basics .. its a pretty easy program, less free hand and more geometric based ... im sure im not even using 1/10 of its power

there it is:
i call it, The Ice Cube
