.....and a cross-section and an assembly as well...don't know about the evenness of the flow with this design, though...

With this design, wouldn't 'hot' water get stuck in the corners underneath the angled barb (not underneath but in the corner), it seems if it comes in at an angle it points straight to the other barb.
Wouldn't that cause the rest of the waterflow to be essentially slower through the block since, water will take the least restrictive path to its destination. Maybe i'm just wrong =). I would try to get the barbs to come in from the top in the corners, you shouldn't have much problem implementing this on a NB block. Now for a GPU block, I'd have the barbs come in on the top side, and have a small divider through the middle of the block creating a small channel. Than again this are just opinions. Pic for reference of statements i posted before. |

The bad thing about the block that I posted is, it is not done proper, it is 3/8'' first of all (not bad, but the channel area does not calculate to 3/8'' ID hose area =\.). Looks wise it is a good block, performance wise, it kills the flow, and doesn't do the greatest job.
If done proper, I think it can be an excellent design. Thanks. -JokerF15 |

Tex 707,
Thank you for your efforts, your CAD work is really good. Most of all the transparant ones. What I have in mind is differant. I'm sure you've seen blocks that have the inlet & oulet on one side of the block and these don't take up any space to speak of which won't then block use of extra card slots. What I have in mind is that the side of the block where those barbs are mounted is cut at a sloped angle so the barbs would rise over the RAM higher allowing use of heat sinks. It might not be possible to cut the base at an angle as well as the top or at least not all the blocks side, so as to not affect the cooling pin area of the block & it's O-ring. Your last two pics/drawings gave me a differant view point regarding this idea. I don't think it will work as well with the thick base involved here. I do think if it were made from a air pin sink that perhaps then it would as the base would be much thinner with the pins rising out of the thinner base. Will take some thick plexi for the top to make it work even there, but it might. Thanks again for your fine CAD work. |

Sorry for my lack of response here guys. I been having to much fun in the New DD block thread. Not to often I find someone that can make an ass of themselfs better than I can! Had to play a little.
Anyway I will be pretty much gone untill Sunday afternoon. I will try and pop in a few replies though. I got to get back to work, then pick the kid up after work, help my brother move stuff tomorrow, work on my freshly rebuilt website (which I hope tex707 will sign up to, need someone with that awsome rendering capablility!), and spend some time with the kid. Keep up the good work guys, interesting stuff! |

It looks like I'm not following you quite well...are we talking about GPU or NB waterblocks here? NB waterblocks are, AFAIK, perfect with perpendicularly mounted barbs...GPU blocks, however need barbs to be mounted parallel or at an angle. There is a 3D model of the waterblock I am using on my video card presented on the previous page....the hoses clear the RAM heatsinks due to a pretty complicated barb mounting design. Please take a look and tell me if you are referring to that particular problem. Thank you for the kind words regarding my CAD work...I think that I have more to offer in that field. |

PostNuke, better than e107
Whatever floats your boat :shrug: Why don't you make the gfx one like the Swiftech MCX(?) 40, with the barbs comming out the side?

I don't need the barbs coming out the side on mine and it would add another 3/4" to the already 1/2" Might get a little heavy being they will be all copper. other than that sure. Danger Den has a nice side mounted one aswell.. |

Tex707,
Yes, I'm talking about a GPU design, I agree with you on the NB. JD, I know the DD block your refering to and it's 45 degree angled barbs are better than the 90's some designs use. I also relize this isn't needed for your currant project. I posted it as being of possible interest to others and perhaps you as well (for the future). I think that if the side of the block were cut at a 35-45 degree angle and then the barbs installed there it would be a improvement over many designs now out. Should offer a bit lower resistence while at the same time improveing the cooling by a small amount. Not try'n to hijack the thread, so I'll not post any more on it, but this has offered me some things to consider. I may not have a mill to make blocks with. But I'm thinking I've enough tools to have a go at something. Tex707 Thanks again. |

What about something similar to xjinn's CPU block for a video card instead?
http://www.procooling.com/articles/a...t-team-wc3.jpg Nothing as elaborate for sure (fewer larger channels would be my suggestion), but it would be fairly low in restriction with all the parallel channels and it would be easy to put 45 degree barbs on the ends to raise the barbs off the ramsinks. |

Here is a simple stress analysis of the Plexi top…in case some of you have wondered how much load it can take, i.e. how much are we are allowed to tighten the nuts that press the springs against the lower washer and the protruding mounting parts of the Plexi top itself.
Yield strength for Plexiglass is 5.5e+7 N_m2, while the maximum stress barely exceeds 3e+6 N_m2 with the force of 50N (11.24 lbf) applied with each spring. This force is, of course, far higher in intensity than necessary to make an excellent contact between the NB and the waterblock. The maximal displacement (at the tip of the protruding Plexi part) is a mere 0.03 mm. All this data is provided for a 8mm thick Plexi top and is not to be taken as an exact calculation because it depends on a meshing size, which should be smaller than I have used. However, it takes too much time to make an analysis that way. Attached are screenshots of a deformed Plexi top - extremely exaggerated, of course, for demonstration purposes only.

I don't think it will bend like that. You have to remember the bolt going through the mobo will keep it from bending. If anything happens it will just break.
Also here is a pic of the block modified to fit my ASUS A7V8X-X. |

About the modification for the ASUS board...there is really a big difference between "standard" ABIT and that ASUS of yours... |

I am not sure why ASUS strayed from the standard, but all their newer boards seem to be like this. I got a dead ASUS A7V333 and it is the same as the ASUS A7V8X-X. |

A7V8X was a crappy board. The Asus boards that are good are best in class (A7V-133 and A7N8X leap to mind) but they also have released some stinkers.
The Asus A7V-133 is the best motherboard I have EVER owned period. |

What I thinking at this point Tex707 is to cut the Lexan 1/2" top (one side) at an angle. Combined with a thin based block with pins raised up out of it I think this can work.
Pins would be approx. .2" (5mm) and the top would be .5" Lexan, with a thinner 1/8-3/16" base. I'll rout a square area for the pins into the Lexan top. Although I may also use a copper 1/2"=>3/8" bell reducer as the inlet to get a bit more water velocity to impact the base with, & a bit of 1/2" copper tube for the open low restriction outlet. A question I still have. Is the .2" pin hieght a good length? I'm open to advice on this as I picked this .2 height as it would be handy to work with along with a 1/2" top of Lexan.
