Ender 3 PSU 92mm Fan Cover
thingiverse
Something I made to replace the stock fan on the Ender 3's power supply. The 92mm fan is the largest I was able to fit on the power supply. The fan I use is this one: https://www.amazon.com/ARCTIC-Silent-Ultra-Quiet-inaudible-Configuration/dp/B0119SG8X4 because it's cheap, inaudible, and good enough for cooling. Way better than the loud 60mm Noctua fan... Just make sure whatever fan you put in the power supply is 12V. PC fans are generally 12V, like the fan linked. Just replace the metal fan plate with this one. You can use all of the same screws to mount it. Just make sure you have some way to jump the fan to the pin header on the board. I used breadboard jumper wires for this lol.
