Update:
For the many people who asked, I finally made a new version of this cooler that is compatible with CRTouch and BLTouch. https://www.thingiverse.com/thing:5236927
The stepper motors on the Creality Ender 3 v2 3D printer are very quiet, which makes the cooling fans the loudest parts of the machine. If the user replaces the included fans with quieter alternatives, the printer will be almost silent during operation.
This mount replaces the original filament blower with two diametrically opposed fans. The mount can be printed on the Ender 3 v2 as a single piece with standard quality and speed settings and support touching-buildplate. Fans can be mounted with M3 screws or super glue.
For significant noise reduction, the user will need to replace all three of the included 40mm 24V fans (extruder, filament, stepper drivers) with four new ones. I recommend the Orion OD4010-24LB. ($12 on DigiKey, https://www.digikey.com/en/products/detail/orion-fans/OD4010-24LB/2621116)
If you really want to go the extra mile, you can also replace the power supply fan (60mm 12v) with the CUI CFM-6015V-122-145. ($7 on DigiKey, https://www.digikey.com/en/products/detail/cui-devices/CFM-6015V-122-145/7605483)
