Bongo Fury

I just pulled a typical cooling fan, there are also larger ones for enclosure cooling like this one at 130CFM it will be a similar power rating well less than 5 watts consumed, and being larger diameter will also be quieter (smaller nosier as RPM higher for a given CFM rating)

The largest size is normally 200mm square, but not a lot of specifications available.
