Don't expect extremely low temperatures, but with a bit of further tuning, it might just work. Wong's system drew 410W from the power wall and hit a temperature of 87°C while being stress-tested by FurMark. However, there are some caveats, as Tom's Hardware points out. The test was performed at a very low room temperature and the GPU temperature hadn't leveled yet when Wong stopped the test.
As you can see, the starting temperature of the GPU was just 18 degrees Celsius, and it topped out at about 87 degrees Celsius before Wong ended the test -- but the temperature hadn't levelled out yet. That's probably a wise call, as the GPU temperature reported is not identical to the peak temperature on the GPU die, but it does show the system's limitations.The site suggests that with a bit of clock tuning and perhaps undervolting, it will be more feasible to passively run the GeForce RTX 3080. The Turemetal UP10 case is priced at almost $800.
