Mother of all Cascades, -100ºc Dual Evap that Cools the Motherboard also!!

I put passed dry nitrogen thought the block, it helps keep the from oxidizing the black all over the outside of the block.







Pressure tested up to 300 psi

Once the blocks are pressure checked for leaks, I was able to start polishing the bottom of the evaporator blocks. The purpose of polishing the block is to make sure I have a flat surface and to maximize the surface contact with the CPU. I started out with 300 grit moving up to 400, 600, 800, 1000, 1200, 1500, and finally 2000 grit.



This is the picture after wet sanding with 2000 grit paper. You check to make sure you have sanding lines all the way across the bottom of the block.



After sanding with 2000 grit I moved up to 0.3-micron polishing wheel. The polishing wheel uses a cloth surface with a 0.3-micron aluminum polish suspended in water.



Once I used the 0.3-micron polishing wheel with 0.3-micron aluminum polish, I move down to 0.05-micron polishing wheel with 0.05-micron aluminum polish. You can see the difference polishing makes in the surface. 2000 grit vs. 0.05-micron aluminum polish.



Once both blocks are done, I moved down to 0.005-micron vibrating polish bath.




Once done you can see the difference from 0.05-micron vs. 0.005-micron but not too well with the camera.

I have to insulate the case that the motherboard and dielectric will be in.





I put 2" of closed cell foam

I will keep posting new pictures as the project goes on. I will also be posting the OCing part when I get the project done.
