Anyone have any idea how loud the marine blowers are? My general assumption would be that they are loud as F### but then again I could be wrong.
Pretty Loud. If you could tweak it to give it less power like a governer or something that would work but, i don't know if you want to tinker with that.
I use a 4 inch running at 5v and I would say that it is quieter than alot of vortex fans. Mine at 12v sounds like a jet is taking off though
