Even Pi 4 B doesn't seem to require active cooling. It will do fine-ish (sitting at barely under the temperature cutoff limit of the thermal throttling, under load, by using a bigger type of passive heatsink), which is still quite a feat. To have a cheap totally silent computer with the specs that 4 B provides is still a great achievement.
