Mother of all Cascades, -100Âșc Dual Evap that Cools the Motherboard also!!
I'm a student at Iowa State University, I have two degrees, on in Mechanical Engineering and another in Industrial. I went to my professors with a idea of a dual evaporator cascade system that will cool both the CPU and GPU down to -100Âșc. I had no experience with phase cooling before I started this project. After looking into what all was needed and all the insulating I would need to do I quickly decided I needed to find a better way to protect the boards against condensation. I had come up with a idea of a sealed case filed with dry nitrogen. I didn't like the idea if my seal breaks everything would fry in minutes after the pressure dropped in the case. I looked at building a controller that would cut the power to every thing if the pressure dropped below a set point. During a meeting with some professors the idea got brought up about using a dielectric. So when I looked into it 3M had a few that would take the temps I wanted to reach. So I switched from dry nitrogen to 3M HFE-7500 dielectric. I worked with Reggie Wing at xtremesystems.org, he has been the number one person that has helped me come up with the design for the cascade system and evaporator blocks.
I have worked with all these people on this project, they have all been a huge help. I will go in to more details when I do the write up for the article.

Builders of the Controller are Mariano Porta AKA Ssilencer & Hernan Martinez Reina AKA Golden Eagle Mail: msporta@2vias.com.ar
The goal is to hit -100Âșc and cool the 3M HFE-7500 dielectric to -40 Âșc to -20 Âșc
