thank you both
i was aware of the change of the cpu ,also that it get hotter but 60°C for almost idle was not expectet . but now its clear that this is safe → beside the 60°C are mention in dietpi as “hot not good”
the zero W has small cpu passiv cooler and on DIN-Mounting plate without a real case https://www.reichelt.com/lt/de/raspberry-pi-hutschienenhalterung-fuer-zero-grau-rpiz-dinrail-p242770.html?&nbc=1
the Zero 2W has no CPU cooler ( i tested with cpu cooler but than i got 2-4°C more heat / i thing the glue pad was not ideal ) and in small acryle case
