I have upgraded tw Ender 5’s with Silent boards. What an improvement!
I can't believe the difference in the noise level of my printer after installing this board, It really is silent other than the cooling fans. This should have been included in the printer by Creality. The install was pretty easy, just take pictures before removing plugs from the old board and put them back in the exact same spots on the new board. Be especially vigilent when moving the wires for the BLTouch as it's easy to get them wrong.
