I made this to attach a Noctua fan to reduce the noise. I used this fan:
Noctua NF-A9 FLX, Premium Quiet Fan, 3-Pin (92mm, Brown) https://www.amazon.com/dp/B00NEMG9B0/ref=cm\_sw\_r\_cp\_apip\_dNnyyiXYDanOZ
The fan is imperceptible.
It's very basic, but it works.
The Ender 3 Pro power supply has 12v fan ports, so no buck converter is necessary.
nb. I think that the original Ender 3 (non Pro) power supply cover has different dimensions and screw hole positions, and this thing is not compatible with that model.
2020-09-27: Added 80mm fan design.
