3D model description

This is a remix of:
Ender 3 Power Supply Fan Silencer
https://www.thingiverse.com/thing:4165310

I reduced a few millimeters to fit the Printers: Alfawise U30, Alfawise U30 Pro, Longer LK4, Longer LK4 Pro.
The holes in the internal fins are to attenuate the noise, using the shock of the air waves in the holes to reduce the noise. Like the holes the car exhaust muffler has inside! I noticed a decrease in noise, but I didn't take the measurement to see how many decibels were reduced!

Installation: A word of advice for the installation. Remove only one screw at a time, otherwise the fan will fall into the power supply. The two sections where the screws go in are quite thin, this is to make sure you have enough thread on the existing screws to install the cover (no need for new screws!).


Sumário em Português
Este é uma modificação da versão:
https://www.thingiverse.com/thing:4165310

Reduzi alguns milímetros para servir nas Impressoras: Alfawise U30, Alfawise U30 Pro, Longer LK4, Longer LK4 Pro.
Os furos nas nadadeiras internas são para atenuar o ruído, utilizando os choques das ondas de ar nos furos para diminuir os ruídos. Como os buracos que o silencioso do escapamento do carro possui internamente! Notei uma diminuição no ruído, mas não realizei a medição para verificar quantos decibéis foram reduzidos!

Instalação: Um conselho para a instalação. Remova apenas um parafuso de cada vez, caso contrário, o ventilador cairá na fonte de alimentação. As duas seções em que os parafusos são inseridos são bastante finas, para garantir que você tenha rosca suficiente nos parafusos existentes para instalar a tampa (não há necessidade de novos parafusos!).
