Comparing the noise of the PS5 in the first launch model to the new, more power efficient, PS5.
Overall: they’re both pretty quiet lol. Launch model has booster coil whine and the new Nidec fan is silent except for the the whistling whirl sound of air being blown out.
From a distance, the new PS5 is slightly quieter due to having less coil whine. The new Nidec fan also seems to blow out air much more efficiently.
