The NerdQaxe++ uses 4× BM1370 ASICs from the same chip generation as the Antminer S21 Pro and reaches roughly 4.9 TH/s (4896 GH/s) at approx. 75 W power draw. That is about 15 to 16 J/TH.
Every unit is built in Germany under CE guidelines and ships with a 540 g solid-copper heatsink and a performance PWM fan. This keeps temperatures lower
