Right the block is actually finished now and here are some pictures of the final completed block.

The layers where soldered together and the pipe connectors where soldered into the top layer which has had copper removed from the corners to lighten it. The entire block weighs 730 grams which is almost exactly the same as the Swiftech MC 462A heatsink and fan.

Once the layers where soldered it was tested for leaks using compressed air @ 5psi with the block in a bucket of water. A leak was found so the entire block was re soldered and re tested. This time there was not a single leak of air and as the water will not be under any pressure I am now confident it is totally leak proof. The block then was milled to remove excess copper and solder then re-tested to make sure it was still leak proof.

It was then pickled in acid for 2 days to remove all the flux and copper oxide from inside the block in the channels and to leave it bare pink copper. It was again tested with compressed air @ 5psi to make sure it was still water tight and it was. It was then finished with a steel brush to give the nice shine it is now.

Now it is totally finished and as I got not that many reply’s to my last post I am again going to ask for you to say if you like it or if you dont. What you would change if you could and why and what you would leave and why. If you could ad anything what would be it and why ? What would you be prepared to pay for it, around £60 ? If not why not.

Thanks for your help as my A-Level course work has to be done my May the 1st so get replying!
