Installation of your custom made container is pretty much like any other heatsink or water block, first you apply some thermal paste on your CPU, then put the container on it, and secure it with your hold down.
I've swapped the plexi ring with a wooden ring! which does not crack under extreme temperatures
Now that we’re ready with the CPU container, let’s make one for the graphics card, the material that you need is the same as for the CPU container. This one is a bit tougher to make though because precision is needed to make this:
The base plate size you can use is 6cm on 6cm and 1cm thick, the holes for ATI and nVidia hold downs can be found here
For brazing this container some improvising is needed. But I found a way to braze it with ease. You just need something or someone to hold it, maybe this picture will give you an idea:
Before you start brazing check the holes with the tube, you need to figure out the position of the tube so you can access all the holes.
I started by brazing the two pieces of tube as this is the weakest point of the construction, heating the bottom works quickest as heat rises, when the copper is sherry red apply the silfoss (or silver) and do the same for the base plate. Double check for leaks before stowing away your gear.
Here’s the finished product:
Sanding down the base plate of the GPU container is not that easy, but well worth it to keep your video card that bit cooler!
Insulation is very much needed on the video card also, make sure you don't skip this step:
The chance is high you’ll be setting up your system outside of a case for these dry ice benchmark runs. To prevent your video card from bending due to the heavy container I made a small wooden “bridge” piece. It’s sort of a rectangle with the middle part removed so you can install the monitor cable.
I hope these guidelines will help you beat that overclocking record by using Dry Ice, if you have any questions about using Dry Ice or building containers feel free to drop a message in our forums
