Having just purchased and received the new upgrade package including the silent board for my Ender 5 in very good time (with no custom charge) I would like to reiterate what a difference it makes to the noise level when printing, when people say that it's silent (apart from the fans) they are not kidding! Also I would like to thank the creality support service for their very quick and efficient support when I encountered a problem with my extruder motor after fitting the new board. They promptly replied with a fix (including photos to help) which fixed the problem first time, I am a very happy camper. Can't fault the products or the excellent service, I would definitely purchase directly in future.
