Very quiet with enough CFM to use with a v6
Rated with 5 out of 5 stars.
this worked great with the v6 in an open-printer, and later with my dragon in an enclosed chamber, works much better than the noctua 40x10 in both cases whilst only being slightly larger

Unfortunately, neither will work as the CR-10S Pro V2 is a 24v machine but the fans are 12v.
