I dont have a CAD program, so I need help finding a free program or a free-trial that can make CADs.
I made the 3d block shown on my previous posts with Hammer (Half-Life 2's map editor :p:)
Go to www.emachineshop.com...It'll let you render your product in full 3D.
Go to File, Export into something you want...It's a DXF format, Then send us the depths of the pockets, fins, etc. It only exports into 2D, not 3D.
Alright, I will model it, but for now it will be a ESTIMATE while I dont have the 7950GX2, so no one waste any materials. :p:Quote:

So in theory those two blocks in parlalel will run same flows.
THen its as simple as bolting it on the card.
THe problem is that I dont have a card and or the cash to buy a cupple of mcw60's to experiment with. In any case it should not be more than an afternoon worth of working to get a block that slips in and bolts on liberaly on to the gpu's.
i think that an awful lot of this thread looks like a reinvention of the wheel. all thats truly needed is a block with a metal top (ie maze4 with metal top rather than delrin) to make it notably thinner and some clever fitting working (ie soldered in flatter-than-usual pipes which return to normal size outside of the card) to make a block.

club3d is coming out with one too.
looks the same as the aquagrafx one.
Yep, aluminum, small tubes = sucks
Sorry but i meant 3dmodel them, I dont have access to cnc right now, but I'll model a reference model of the card (I'm trying to find some pics of a 7950GX2 without cooler) and a couple of watterblocks with 3dsmax.Quote:

Thanks for the pics:), I've already started moddeling the card itsself with 3dsmax so I think I'll model some watterblock's for it.Quote:

ok guys, I ordered a XFX 7950GX2 (520/1300) for $540 from Buy.com :woot:
Im getting it in about a week or a week and a half, since I selected budget shipping to get free shipping.
I wont make the 2D modeler from emachineshop for now. Was a bit complicated estimateing each measurement.
All I did is calculate the possible chanel dimensions.

I would work with #2 in between the cards, because it doesnt change as much from the 1/2" fitting, but its thin enough to put it in between the two cards. I would probably make the top a verry thin brass top to make the base a bit more beefy with copper.
@ Mad Max
When I get the 7950GX2, Ill give you the exact measurements so you can model it in 3D Max.
Could you model the block I designed, or do you have any other ideas?
So I guess Ill give the dimensions, Mad Max (or anyone else) models it, and Burn or Got Chow (or anyone else) can build the beta and final design.
Sound ok to you guys? :)
http://www.theinquirer.net/default.aspx?article=32816
waoh, now evga is selling them with the water blocks :D. It makes it sooooo much easier. Just plug it in :D It looks sexy too.
I hope no one posted this. I dont wanna feel retarded again -_-
There are some problems with buying that 7950GX2:Quote:

Its going to be a problem for us 1/2" loop users.
3) Performance will suck since it cools the GPU, the memory, and the SLI controler, which will make the block pretty restrictive. The GPU will produce a lot more heat and will benefit more from the cooling than the other stuff. The other stuff can run well with copper heatsinks without artifacting.
I already bought a XFX 7950GX2 520/1300 last Sunday, so I wont be buying that card anyway.
The shipment is going to take a bit of time. About a week or a week and a half (probably business days)
When I get the card, I will post again with detailed measurements of the area where the GPU is, and Ill sketch a picture of my concept block with all the measurements so a CAD modeler can make the 3D CAD file.
Then the 3D CAD modeler gives the files to someone who has access to a CNC machine so he can build a test block. If it works well, then he can make the final design.
If everything works right, someone could make these blocks for people interrested in 1/2" blocks for their 7950GX2.
Whoever wants a blocks would just have to pay the CNC Block builder for the materials. It should be a lot cheaper, and it should perform better than those retail versions.
While we wait until I get my card so I can post the measurements, could we discuss about a better design?
Is my block the optimal design, or is there a better method of building this block?
Those who are experienced with block building, please give some recommendations in block building
Review of my final block design (no measurements atm, of course):

damn, its 1/4? Can you tell what material that is? Is is alu?
Googled it to see if there were more pics to see if its made of Alu.Quote:

This is the 7900GTX version, tho, but it looks about the same, only more separated.
As you can see its 1/4" tubing like I said :p:
The 3 plains connecting looks like a pretty restrictive solution.
If you look closely on the edges of the block, the chanels could be made of Alu.
Look at the edges I circled in this pic:
http://img344.imageshack.us/img344/3...gablock3kn.jpg
I wouldnt look for the easy way out of this problem.
Watercooling the GPU and passively cooling the rest seems to be the best solution for the 7950GX2, and for extreme watercooling 1/4" wont do the trick ;)
BTW, I just got an email from Buy.com saying that the package was just sent. FedEx estimates that the package will get at my house this Fryday.
This weekend I may get the measurements for the 3D CAD modelers, so lets not let this thread die yet :p:
jopapa1267, you could propose new designs while you wait for the custom blocks to get done.
Aren't EVGA's 'Black Pearl' coolers made by Innovatek? If so, I think almost all of their GPU coolers are aluminum.Quote:

*edit* - If you look closely I think that's even the Innovatek logo on the cooler itself
http://www.innovatek.de/contentServ/...mages/logo.gif
I posted this in another thread... figured it could belong here to. Would avoid having to make the blocks, and should be a good solution when combined with some good BGA ramsinks and a fan.
More commercial alu solutions for 7950GX2 cooling, blech.
Now, I'm not one to support ThermalTake, because I think 99% of their products suck... but: This one product has possibilities.
http://www.thermaltakeusa.com/produc...8/cl-w0088.asp
It's just a plain jane GPU block, make out of copper. Downside is that it "only" has 3/8" connectors. Upside is that it fits on the lower core of a 7950GX2, so it'll work.
Here is what I was thinking to make it work. Get two of these copper TT blocks, mount them on a 7950GX2 with 3/8" connectors. Connect both inlet ports to a Y with 3/8" barbs after the Y, and a 1/2" or 7/16" barb before the Y. Do the same for the outlet ports.
Flow is split, yes, but it should be ample for this block, and avoids excess tubing which means avoiding extra head loss.
It's not optimal, but it's better than the commercial solutions like the black pearl and whatnot.
Here is a pic illustrating what I mean. :)

You're 100% right, it is an Innovatek block ... ALU body with a copper GPU-core blockQuote:

I think the Black Pearl before had also an Innovatek block
Yeah, Ive already thought through every possible cooling solution for the 7950GX2 that will be cheap and efficient, and customizing 1/2" blocks seems like the best solution.Quote:

The solution you posted above will be a bit restrictive and expensive.
Each TT CL-W0088 block is verry overproced, considering that little materials are needed to build that block and it uses 3/8" fittings.
Here's an example I found:
http://www.nintek.com.au/x/scripts/p...idproduct=6108
Ive been asking for block design alternatives, but people keep posting easier, yet more expensive and less efficient cooling alternatives :stick:
Today Im getting my XFX 7950GX2 so I will post the measurements within the weekend, so people can make GPU block models with it.
I will also post measurements of my GPU concept block for 3D CAD modelers so we can start building blocks.
Calling all 3D CAD modellers
7950GX2 measurements are available:
These measurements are very accurate (no estimating here)
Measurements were done in centimeter and milimeter scale and I converted each measurement into it's inches equivalent.
If you were to print it to scale, it would match an actual 7950GX2 within a milimeter of precision.
There is only 1 error, tho. The SLI controller is only 1mm - 2mm lower than the actual 7950GX2, but it doesnt affect block building by much anyway :rolleyes:
NOTE: These are verry large high res JPEG pictures of about 1.3mb each, so expect them to load slow.
Also make sure to click the image to see it in full size so you can read the measurements.

At the moment Im trying to find a way to design my waterblock using the measurements I maid above, but its very hard since the tubes have to be very wide to compensate the height in the chanel.
The width of the chanels either overlap the screw location, or the inlet and outlet tubes are too close together that it makes the block too restrictive.
I will have to change my U block design to my original L shaped design and Ill have to overlap a pair of memory chips on the top and on the right side since the chanels are a bit wide.
Since a L shape is less restrictive for heat disipation, Ill have to sketch the fins to be a bit more restrictive.
Sketching my block design with all the measurements will probably take me until tomorrow or the day afther that, since I dont have as much time to work on it during work-days :(
Please take advantage of my measurements to come up with better designs.
If you think you have a better design, I could sketch it with the measurements during weekeds since I have more time.
If you have any questions about the measurements, feel free to post.
Let the modding begin! :woot:
ok guys, this is what I have so far:
I scratched out the L design and found a way to make it the U shape again. Memory cooling on top just wont be symetric like I wanted :p:
The good thing about this design is that it uses less material, its easier to build, it looks better, and it seems to be the best balance between flow and resistance.
With this design you also only need one pack of 8 ramsinks, since 8 memory chips are already being cooled by this block :)
PLEASE NOTE THE FOLLOWING:
1) This is a unfinished sketch. I just put it up as a quick preview, since I may have to delay my final design until the weekend :(
2) I havent added the fins, because I dont have a compas and by hand its going to be a bit of work since each fin will be about a milimeter thick.
3) The path in between the memory block, and the waterblock is a 1/2" copper pipe morphed into a oval shape and welded in between the two blocks, and the path on top is the same thing but it changes from the oval shape to a regular 1/2" fitting. I didnt add a cilindrical effect by shadding it, since its not my final design.
4) The portions of the memory block that are not being cooled by water will have a heatsink design to disipate heat on air in that area.
