Duct fan… LOUD!

 
 

Hey all, long time lurker and rare poster asking for my fellow blade’s advice,

I installed a 4" duct fan in my cabinet today, with a 4" flange. Works great, constant temp of about 82f and humidity in the 30% range. HOWEVER the fan is a bit loud, not in itself, but the vibration it creates from the fan, into the flange, and through the fiberboard is quite annoying. More of a low hum than loud, but definitely annoying.

Does anyone have any suggestions on how I can reduce this? I’m thinking I could reinstall the flange with a thing layer of silicone on the mating surface, and around the hole I made in the cabinet with hopes of negating that vibration travel. Also, does anyone have any recommendations on how to hang/mount the 4" fan? Right now it is supporting itself by the flange, which works, but is definitely contributing to that nuisance vibration.

Any helpful ideas are much appreciated,

Regards,
Rasta
