The Best Fanless Thin Mini-ITX Case Showdown

What is the best fanless Thin Mini-ITX case? I did a direct comparison of four Thin Mini-ITX heatsink-cases that I could get my hands on. Included were the Streacom FC2, Akasa Euler S, Akasa Galileo T, and Turemetal UP2. There are other versions of the Akasa Euler and Galileo, but these two are my favorites. I tested the four heatsink-cases with the same components at various power levels to see how each case does under the same conditions. I ran Prime95’s torture test with small FFTs for half an hour during each run. This was done a total of 12 times, increasing power limits at 10 watt intervals from 15 up to 35 watts. I changed CPU power limits quickly between each test so that the coolers lost as little heat as possible. This way I could get to heat saturation more quickly during each run. CPU core temperatures were tracked with HWINFO64. Over 17,000 core temperature readings were recorded and processed to compile these results. After a lot of averaging, I was
