Fan Noise ENDER 3V3KE (#modmy3dprinter)

Does anyone have any ideas or mods to minimize the fan noise of printer (Ender 3V3KE) which won’t rob my wallet???

Something like this? Ender 3 v3 se cooling tuning to 40mm and dual 5015 fans by Serhio_K - Thingiverse not tried it yet but I am sure I spotted a 24V noctua fan the other day. Planning on doing this to my SE, something like this should work on a KE too.
