I would like to share some thoughts with you regarding the loudness and the temperature. What did you want?) According to the video evaluation of the curling iron, it had a radiator with pipes and a cooler inside of it. The prefix, on the other hand, housed such strong machinery in such a small space that there was neither a powerful fan nor a large number of heat pipes. In addition, the noise it produces is noticeably less audible than the noise produced by the power supply fan of a standard, lower-end personal computer.
