Silent Fans Upgrade Creality Ender 3 S1 Pro Duct System

FIRST OF ALL: You are not forced to print both part. You can keep one of the two "stock". The cooling duct is based on the "Stock Creality Sprite Fan Double Duct" from Sorkin and adapt it to fit a blower fan 5020 24VDC on it. It is super quiet and really effective. The Hotend duct is a creation of me, I wanted to keep the BLTouch exactly a the same spot. You'll need for this assembly; - 4x M3x10mm - 2x M3x25mm - 3x M3x6mm (optional, can re-use the stock one) - 1x M3x6mm button head (optional, can skip this screw and the assembly is stiff enough) This screw is necessary behind the BLTouch, but as I've said before, it is optional. - 1x 5020 Blower Fan 24VDC, here is what I've used: https://www.digikey.ca/en/products/detail/mechatronics-fan-group/B5020L24B-BSR/5209733 - 1x 4010 Fan 24VDC, here is what I've used: https://www.digikey.ca/en/products/detail/cui-devices/CFM-4010C-265-251/15765267 Yes you can use any other fan that fit the same dimensions as the one I've used. 24VDC is a little more loud but you don't need to install a buck converter on your harness. The rest, you can reuse the stock screws from the stock duct.
