While the exact working principle of the SmartMelter is still secret – we have discussed thermal conductivity before as a potential problem – but on the other hand, some parts need cooling, too – one of many parts involved in that will be a watercooling cycle consisting some 3D-printed parts as well as yes, a 360mm radiator the kind you would find in a watercooled PC – except the fans on top are of the very powerful but also very loud variation – and sharp edged. Also there are some 3D-printed placeholders making for a tiny bit of space between the radiator and the fans to improve airflow distribution.
It has gone through some rough testing since it will be exposed to higher flow rates and thus backpressure then it would in a PC but it’s within it’s official certified range and it also passed a practical test.
