I need to post some pictures of my thoughts, what my new prototype waterblok for R9800 is going to look like. Welll with a little modification it can also become the x800 waterblock.
As you can see from the pictures there are basically two blocks - one on the fron and one on the back of the card. I decided to realize the water connectors on the back of the card so they are turned upwards when the card is inserted. The crossection of the channel milled in copper is 128 sq mm. That is exactly 1/2" sq. Above the VPU are planned some fine finns to maximize the contact area with water. This design on this model is planned to be made out of copper and policarbonate. But I can also solder a copper top to the base in almost no time. There were some major difficulties with designing, because of unsutable position of mounting holes. So I decided to hard solder the screws in the base of the GPU side block. That way I won't have too much flow restriction. Although the design is almost final I would like to hear some comments and maybe if there are any suggestions from any of you. Here are the pictures: - GPU side of the block ![]() ![]() - back side block ![]() ![]() - Assembled preview on a card model ![]() ![]() ![]() ![]() |

what size endmill are you planning on using? Those little fins will be difficult!

Fins are only 0.5mm thick with 1mm space between them. And that part is not going to be milled, but I'm going to use a small HSS saw to cut the fins.
I already made my whitewater clone CPU block that way. |

You might consider making an allowance for an o-ring: it'll give you a better seal, and it's easily taken apart, over and over.

Well... if you take a realy close look, you can see the O-ring on pictures of the model. Unfortunatelly the texture of the rubber isn't too good so it is hard to differentiate it from copper.

Wow, that looks really nice. What is the material that joins the two halves and what is used to seal those junctions?

looks good, the only thing that doesnt feel ok, is the sealing around the lower mounting rod in the last pic.
maybe you should try a rotor style over the core instead of a micro channel, easier and might even work better in this situation. |

Looks great, very nice models Jackal!
I'd suggest placing inlet over VPU finned area and split coolant into two streams for mem modules. Look at jaydee116s block and imagine central inlet and two side outlets. In your case no outlets but channels over mem modules and to the other side. The most beneficial way of cooling a vid card is to cool its VPU, passive copper heat sinks are more than nuff for all but extreme volt modded specimens (some peeps totally denounce mem chips cooling as counterproductive) |

could he have issues with cracking the poly? seems like there would be alot of pressure especially in the middle of the front side, with the O ring pushing up with no clamping force in the center

If i were you id add a bolt to hold the blocks together on the edge where the they over hang the card, just for piece of mind. Other then that looks very nice

Why do you need the o ring in the middle of the card? I suggest you spare your block the strain of the middle o ring and simply make the o ring go on the outside edge.

Just drop the middle O-ring, it serves no purpose.

kinda reminds me of this http://www.ocforums.com/showthread.php?t=274756
maybe you could use the way he cools the core, it looks abit more effiecint |

That is the sexiest block I have ever seen.

How do you go about getting an o-ring shaped that way?
Its not hard JD ![]() ![]() |

If you look at previous works posted by jackal, it's clear that he desserves the title of "the most accurate humanized CNC machine" ![]() |

![]() But I think the days when I was making my waterblocks on a drill press are finally over. I managed to get an agreement to use the mill at my father's workplace. Of course only when it's free. Unfortunately that's mostly over the night. But that isn't a problem for me. And it's a huge mill (Prvomajska) over 4 meters high with 40HP engine and hydraulic XYZ table with manual or automatic feed. Unfortunately this last weekend the mill was fully ocupied by others so I couldn't get any work on the block done. The other problem is that the block probably won't be finished before than in two to three weeks, because it's the end of semester at our faculty and I have to study hard for some exams and I live approximately 150 km away from home (I study at the faculty of electrical engineering - electronics & microprocessor systems - 4th year finished now). The good thing is that I choose to make a microprocessor controlled CNC controller for one of the subjects to pass ![]() |
