-100degC cascading CPU cooler


From a thermodynamics standpoint this project is damn near pornographic. The goal is to cool both the CPU and GPU down to -100 degrees Celsius using a dual evaporator cascade system. The project is fully documented starting with making the CPU/GPU blocks and polishing them to 0.005 microns. Next step is the case build up followed by a ton of brazing. He got everything assembled and pressure tested with only a few bugs. Right now they’re troubleshooting the system. They can get one of the heat exchangers down to -48.9degC, but not both. I’m sure they’ll get through this. Head over and check out the beautiful work they’ve done so far.

    Everything’s easier when you have an ENTIRE SHOP with mad tools available for use.

    I wish I had access to sweet stuff like that.

    All I can say is wow I wish I knew how to do all that stuff. Maybe I should go to school for it just as a hobby. I think it would be worth it. It would also be awesome to have access to all those tools at a school. I wonder if you could still use their shop once your done going to the school. It probably just depends on where I go I guess.

    Wow… It must be nice to have the time and resources for this?!

    This type of cooling for overclocking is very popular. Xtremesystems.com has many people that can help you get started.

    you mean train as an HVAC tech? I am hard-pressed to imagine how dull that would be.

    Will the Semiconductors work at -100 C? It seems like there wouldn’t be enough thermal energy to kick them into their conduction bands. This might be too much of a good thing.

    Looks like another project brought to you by methamphetamines.
