Oh yes. Sdumpers unloaded towards -150C. Coldbugged motherboards and RAM too
The CPEV on all stages will allow a certian amount of dialing in of the temperature. Unloaded might be below -150C with the valve closed, but real useful tuning around -125C at i7 loads is a good goal. It will have a hot gas bypass as well for expressedly warm situations, and a controller on that to actually have it control a temperature automatically.
