The "Whisper Quiet" Ender 3 PSU Mod.
The fan in the original Ender 3 PSU is a touch loud, mine comes in at around 53dB. the "normal" method of installing other fans and using a buck converter to regulate the voltage is fine... but just using the buck converter to lower voltage going to the existing fan is cheaper, doesn't require extra modifications, and yields amazing results.
My Ender 3 now only produces 37dB, no louder than a whisper.
