Meanwell Fan Silencer

thingiverse

This fan silencer fits a Meanwell 320W power supply. It reduces the perceived sound level by about 3db as measured by my iPad or about 19%. Not much but it helps to quiet it down a bit. Also, at the intake end it is possible to put a small piece of porous foam or similar material as an air filter, if needed. You will notice there is only one screw holding the silencer in place but it is enough, friction does the rest.
