my GPU waterblock design.

crxy_sasquatch · 07-16-2003, 01:58 AM

Since I'm a novice to constructing waterblocks, I decided to construct one for the gpu first, since it is less important.

I came up with this simple zig zag flow.

The holes and the slots are the same dimension (11/32 inches)

I'm not sure about the gpu mounting holes,

I have a Chaintech geforce 4 ti4200.

Can someone supply me with the correct dimensions for their mounting holes?

thanks!

oh yeha, the whole thing is 75x60 mm.

which is about 3 inches x ~2.4 inches

We also have a milling machine at my school, so cutting this out shouldn't be too difficult. I've herad that the copper will start to sort of melt and loose its shape while drilling, so freezing it would be the best bet?

I know the dimensions of all the mounting systems are around here somewhere. Look under the piles of clo...I mean do a search and you'll find them. I can tell you now the block you made is to big. Most GPU blocks are less than 2x2. Any metal will deform slightly when heated. Use a lubricant, WD40 will do but its a pain to get off. This will keep it cool and help the material to get away.

Freezing it would just buy you a few seconds because it would still warm up. If you want to keep it frozen get a can of air(duster), turn it upside down and deepfreeze the sucker.

Copper only starts melting at over 1000º C. This won't be a problem.

However most materials machine better when they are kept coolish. The best way to do this is to have a constant coolant stream.

You'd do just as well to have an 'open plan' block, get rid of the channels, they'll only cause restriction/head~loss. No cooling improvment(worth mentioning, if any) :shrug: ...

Copper does get 'tacky' when hot. It will grab at the milling bit. Liquid coolant or liberal amounts of WD40

I just want to know where I can get the "Square" endmill he's going to use on those 90° turns!
